R. Caroll (eds.) (1988). Atlas of Breeding Birds in New York State. Comell Univ., Ithaca, New York. Method: The Breeding Bird Atlas contains the results of a state-wide effort to determine the breeding birds species in New York State. The project was sponsored by the Federation of New York State Bird Clubs Inc., the New York State Department of Environmental Conservation, and the Cornell University Laboratory of Ornithology. This document provides compiled data from more than 200,000 field hours of work conducted by 4300 volunteers over six year period (1980- 1985). The reader is referred to. this document for additional details of sampling and data compilation methods. For the purpose of the National Estuary Program Nomination Document, the Breeding Bird Atlas was used to determine confirmed and probable breeding species within the study area. The boundaries of the Peconic System study area were superimposed on the graphic representations of breeding "survey blocks" provided in the Breeding Bird Atlas. Breeding sites are accurate to within a 5 x 5 km survey block. Breeding blocks were included for those areas. detemiined to be within and immediately adjacent to, the Peconic System study area. Owing to the reduced scale of the Breeding Bird Atlas maps, it is likely that some species may have been inadvertently overlooked or inaccurately recorded. It is notable that the majority of breeding blocks were located entirely within the boundaries of the Peconic System study area. Thus, it is believed that the summary results provided below are reasonably accurate and sufficient for the purpose of this study. Discussion: Information contained in the Breeding Bird Atlas indicates that approximately 125 of New York State's 245 confirmed breeding species have been documented as breeding with the Peconic System study area. An additional 15 species are considered to be probable breeders within the study area. - The combined number of confirmed and probable breeding species represents approximately 57% of New York State's breeding birds. The importance of this percentage is underscored by the fact that several of these species have been listed under New York State and MW Federal endangered species regulations primarily because of their state-wide and (in the case of the piping plover [Charadrius melodus ) national rarity. Listed species confirmed (C) or probably (P) breeding within the Peconic System study area include the following: Common barn owl to alba),(C) - NYS special concern Common tem Sterna hirundo),(C) - NYS threatened Eastern bluebird Sialia sialis),(C) - NYS special concern Grasshopper sparrow (Ammodramus savannarum), (C)- NYS special concern Least bittern (Ixobrychius exilic), (P) - NYS special concern Least tern(Stem a antillarum),(C) - NYS endangered Northern harrier Circus c anus ,(C) - NYS threatened Osprey Pandion haliaetus),(C)- NYS threatened Piping plover (Charadrius melodus ;(C) - NYS & US endangered Red -shouldered hawk Buteo lineatus ,(C) - NYS threatened Roseate tern(Stem a dougallii),(C) - NYS endangered Vesper sparrow, (C) (Pooecetes gramineus) In addition to those breeding species listed pursuant to state and federal endangered species laws, the Peconic System provides confirmed breeding habitat for many less -common species many of which are generally catagorized as "area -sensitive" or "forest -interior" species. Many of these species have been locally extirpated from areas of increasing human disturbance, habitat fragmentation and development. Support for this position can be found in the results of recent research involving the woodland characteristics affecting breeding bird diversity. Such studies have shown that woodland size and vegetative structural composition (shrub layers) are among the most significant factors affecting breeding bird diversity (Tilghman 1987; DeGraff and Wentworth 1981; Robbins 1980). On Long Island, rapid development and human disturbance have resulted in the isolation and local extirpation of area -sensitive species at many locations. Such species are now found commonly only in large undeveloped woodlands like those remaining in the Peconic System. Within the Peconic System, breeding has been confirmed for the following area -sensitive species: Ovenbird Scarlet tanager Red -shouldered hawk Broad -winged hawk Yellow -billed cuckoo Seiurus aurocapillus) Piran a olivacea) Buteo lineatus Buteo platypterus) Coca zus americanus) IM Great crested flycather Eastern wood -pewee Wood thrush Veery Yellow -throated vireo Red -eyed vireo Black -and -white warbler Pine warbler American redstart (Myiarchus crinitus (Contopus virens (Hvlocichla mustelina Catharus fuscescens) Vireo flavifrons) ireo olivaceus Mniotilta varia (Dendroica inns Seto ha a ruticilla) In addition to the above-mentioned species, the significant diversity of habitat types provides for the breeding of numerous other species listed below.

Sampling was continued for five hours beyond the last of the significant rainfall. Total nitrogen concentration rose from 0.2 mg/l to 0.5 mg/1, peaking within a few hours of the first major burst of rain. Virtually all of the nitrogen increase was seen in the organic portion of the TKN. Nitrogen loading increased from approximately 2 lb/hr total nitrogen to 5 lb/hr at peak loading. Nitrogen concentrations and loadings appeared to drop to pre -storm levels within about 12 hours of peaking. While sampling was carried on for several hours after the cessation of rainfall, longer-term effects of the storm could not be verified due to a lack of sampling. Nitrogen concentrations at the Grangebel Park section of the Peconic River were consistently at least 10% higher than concentrations at the gauge. Phosphorus concentrations stayed fairly level throughout the first 12 hours of the event at about 0.11 mg/l total phosphorus before dropping to about 0.08 mg/l total phosphorus by the end of the sampling event. Phosphorus loading increased from about 1.05 lb/hr total phosphorus to about 1.2 lb/hr total phosphorus. This increase in loading was mainly due to increased flow rather than increased phosphorus concentrations: Total phosphorus loading ultimately decreased to about 0.8 lb/hr by the end of the sampling event. Phosphorus levels at Grangebel Park were higher than the concentrations at the gauge. F-1 BTCAMP Stormwater Runoff Samppling Peconic River Gauge, May 1 -May 2, 1989 Page 2 Coliform levels ranged from 500 to 2400 mpn/100 ml, with no clearly discernible trends evident in the data. Metal concentrations were not appreciably elevated during the storm. Iron concentrations were about 1.15 mg/l in the Grangebel Park section of the river, about 35% higher than the 0.85 mg/l that were present at the gauge. Manganese concentrations were similarly higher at Grangebel Park than at the gauge,'where manganese was present at about 0.17 mg/1. To put,the data in perspective, nitrogen levels at peak concentrations were still slightly lower than the 1988-1989 average of about 0.6 mg/l while phosphorus concentrations were approximately the same as the 0.10 mg/l 1988-1989 average. Total nitrogen and phosphorus peak loading, however, were about twice the average 1988-1989 loading. The data collected in this May 1 - May 2, 1989 wet -weather sampling run of the Peconic Gauge should be used with caution due to a long lag (13 days) between sample collection and sample nutrient analysis. The next run will ideally occur after a longer period of antecedent dry weather, as the heavy' rains which occured within 72 hours of the May 1 - May 2 sampled storm event possibly lessened the impacts of the stormwater runoff generated by the storm: Depending on the hydrodynamics of the river, sampling and monitoring may also - occur on a daily basis for a few days after the next sampled storm to measure the possible effects of post -rainfall bank storage on the river.

Sampling parameters included total and dissolved nutrients (nitrogen and phosphorus components), coliform bacteria, and metals as well as other physical parameters. The sampling event was preceded by approximately ten days of dry weather, making this storm a good candidate for study. The subject storm ultimately deposited 2.22 inches of rain over a twelve and one-half hour period. This autumn stormwater runoff sampling event follows an initial stormwater runoff sampling effort which occurred in the spring (May 1 and May 2, 1989). DATA TABLES AND GRAPHS Attached are the following data tables and graphs which summarize the data compiled subsequent to the Peconic River wet - weather sampling event: i Data Tables • Data Summary • Nitrogen and Phosphorus Data • Coliform and Metals Data Rainfall Data • Peconic River Flow Data Graphs • Rainfall Data / Peconic River Flow Data • Nitrogen Concentrations, USGS Gauge / Grangebel Park • Phosphorus Concentrations, USGS Gauge / Grangebel Park • Total Nitrogen Concentrations / Total Phosphorus Concentrations • Total Nitrogen Loading / Total Phosphorus Loading F-11 BTCAW Stormwater Runoff Sampling Peconic River Gauge, Oct 31- Nov 1, 1989 Page 2 SUMMARY OF DATA Peconic River flow remained relatively unchanged for the first eight hours of sampling, by which time about a half inch of rain had fallen. The flow then increased sharply from 68 to 86 cubic feet per second (cfs) over a five hour period, when an intense period of rainfall raised the total.measured rainfall accumulation to its final level of 2.22 inches. The final sample was taken eight hours after peak flow, -at which time the flow,appeared to be stable at 83 cfs. Unlike the May 1, 1989 stormwater runoff sampling event, when organic nitrogen and, correspondingly, total nitrogen clearly increased and peaked, there was not a clearly discernible trend in any component of nitrogen concentration during this event. For both,the USGS Gauge location and the Grangebel Park station, nitrogen concentrations at the end of the rainstorm were -lower than initial sample concentrations. The ultimate increase in nitrogen loading was less than proportional to the increase in river flow. Loading at the Grangebel Park location could not be determined due to a lack of flow data. In the case of the USGS gauge station, TKN jumped from .37 mg/l to .58 mg/l during peak flow before suddenly dropping to a non- l detectable level and finally returning to a level near the_ initial sample concentration. Nitrate concentrations at both sampling points remained relatively unchanged, and ammonia -nitrogen was generally not detected. Thus, the organic component of TKN was responsible for most of the nitrogen concentration fluctuation. Nitrogen concentrations at Grangebel Park were more random than at the USGS station, and total nitrogen concentrations at Grangebel Park were generally in an average range of 10 to 20 per cent lower than at the USGS Gauge. Phosphorus concentrations as measured at the USGS gauge station were also lower after the rainfall than prior to the start.of rain. At Grangebel Park, however, phosphorus increased noticeably from 0.03 mg/l at the outset of sampling to a peak of 0.101 before dropping to a post -storm concentration of 0.04 mg/1. Phosphorus concentrations at the USGS gauge were noticeably higher than at Grangebel Park, with a concentration of 0.092 mg/l for the final sample. However, phosphorus loading at the USGS gauge was lower at the end of the storm than at the outset of the sampling event. Total coliform concentrations at the USGS Gauge station were all less than or equal to 3000 mpn/100 ml, except for the final sample which was 30,000 mpn/100 ml. -Coliform levels at Grangebel Park were somewhat higher, with the last five samples greater than F-12 BTCAMP Stoimwater Runoff Sampling Peconic River Gauge, Oct 31- Nov 1, 1989 Page 3 or equal to 6000 mpn/100 ml. Meanwhile, iron and manganese concentrations at Grangebel Park were approximately 0.6 and 0.06 mg/l, respectively, considerably lower than the 0.9 and 0.12 mg/l present at the USGS Gauge. All other metals parameters were present in non-detectable concentrations. The Grangebel Park site was chosen in an attempt to measure the effect of stormwater runoff from some of the more urban areas along the Peconic River. Without the ability to gauge the flow at this portion of the river it is difficult to meaningfully interpret the Grangebel Park data as anything'more than a gross qualitative indicator. It is, nevertheless, interesting that nitrogen, phosphorus, iron, and manganese concentrations were lower at Grangebel Park than at the USGS gauge station. The explanation for this difference is not readily apparent. One consideration is that, although the Grangebel site is the last location at which non -tidal Peconic River flow can be measured, the bulk of urban stormwater runoff contribution occurs downstream in the tidal estuarine portion of the Peconic system. Another confounding factor in the analysis of the Grangebel Park data is the influence of Little River flow contribution, which is also undetermined. In addition, the Grangebel Park sampling point'may not have been as ideal as the USGS gauge station for obtaining representative flow, as the dams and culverts were either littered with organic debris and were dangerous to access. Thus, the Grangebel Park data should be used and interpreted with caution. The event mean nitrogen concentration of 0.68 mg/l for the October 31 sampling event was in the range of the 1988-1989 average concentration of 0.6 mg/l while the phosphorus concentration of 0.074 mg/l was lower than than the 1988-1989 average of 0.1 mg/1. Both.nitrogen and phosphorus loading rates of 10.87 and 1.2 pounds per hour were considerably higher than the 1988-1989 rates of 2.63 and 0.46 pounds, respectively. However, the elevated loading was due to greatly increased flow. The -1988-1989 loading rates were based on flow data obtained between January and April, when flows were approximately 16 cfs, much lower than the mean flow of 71.6 cfs during the stormwater runoff sampling event.

Station PRI is located 2 to 3 meters (6-9 ft.) north of the west corner of the bulkhead at what is now MacDonalds. Depth at mean low water is 1.5 meters (4.5 ft.). The normal color of the water over 15 years is usually a transparent brown reflecting the bog -like character of the river drainage to the west. Secchi disc transparency (table II) has varied from 2.1 to 0.2 meters with no marked pre "brown tide" or during "brown tide" difference. Average salinities (fig. 8.1 and table II) at the surface ranged from 0.63 to 15.5 ppt. and usually remain below 5 ppt. Bottom salinities ranged from 12.0 to 24.5 ppt. As would be expected in this area of fluctuating surface fresh water input, temperature and salinity are highly variable. This is primarily the result of the well-established "salt wedge" due_to the greater density of the normally cooler saltier bay water at the bottom overlain by lighter, warmer, less saline surface river water. Both, dissolved oxygen and nutrient (nitrogen and phosphorus) concentra- tions at the bottom are affected by this salt wedge. Oxygen values are consistently below the 2.5 mgm/l minimum necessary for the survival of most plant and animal life. Ammonia nitrogen accounts for approximately 1/3 of the dissolved nitrogen at Station PR1 (fig. 8.2, 8.3) . Data for the years 1985-87 is not complete for this station, but the NO3-N spikes (figs. 8.4 and 8.5) approaching 90 ugat/1 on flooding tides tend to confirm a bayward origin. Bacterial decay of the algal bloom organisms is one possible source for the high nitrate nitrogen in this salt wedge regulated, nutrient trap area. H-17 --- The actual location of anchoring the research vessel and sampling at station PR3 has varied over the fifteen year period due to bridge construc- tion, increase in size and use of shore line facilities, and public navi- gational access considerations. Depth in the channel varies from two to three meters (6-9 feet) and is consistent up to the bulkhead of the Riverhead Yacht Club docks. Located in this bulkhead just below the mean low water mark, is the Riverhead Sewage TYeatment plant outfall. Since 1985 this same outfall has served the Southampton -Riverhead Tbwns tertiary scavenger Waste TYeatment Plant as well. Secchi disc transparency has varied from an average ebb 0.3 meter in 1975 during a period of low dissolved oxygen and a menhaden (Brevoortiatyrannuz) kill in Peconic River, to as much as 1.7 meters in 1980 on a flooding tide (table IV). 1985-87 secchi depths, have averaged less than 0.5 meters. The marked salinity gradient at station PR3 is due in part to the sewage treatment plant effluent. Surface waters average approximately 8 ppt. less than the low twenties of the bottom samples. Station PR2 (S®H station 280) displays an even more significant salinity gradient (table III). In 1975 the sewage treatment, plant discharged 0.7 mgd (million gallons per day) of secondarily treated wastes (Hardy 1976). The combined plant today discharges 1.3 mgd (personal communication NYS DEC). The average discharge rate of Peconic River over a 32 year period was 23 mgd in 1975 (Hardy 1975). Dissolved oxygen at the surface has ranged from 3.9 to 10.0 mgm/l, remaining reasonably high (80- 90% saturation) for the fifteen year sampling period. Bottom D.O. was fre- quently half that of the surface. At one sampling dated in 1980, chlorophyll a concentrations (177 mg/m3 at the bottom) exceeded the "Brown Tide" years by a factor of three. H-18 Station Station PR5 is located off -the north shoreline of Indian Island, the eastern most portion of,the county park. When possible, samples were taken directly at the mouth of Meeting House and Terry's Creeks in 3 meters (9 feet) of water. Often times, however, sport fishing from the shore and boat traffic made.it necessary to relocate the precise sampling site away from the channel. This station was selected because of the extremely high nutrient input at the headward reaches of Meeting House Creek below a duck farm and processing plant, Station PR5A (see Appendix) and near SCDH SM.220. Average nutrient values at station PRSA have consistently been highest (up to 850 ugat/1 NH3-4 of all Peconic System stations. Secchi disc transparencies have varied from 0.3 m in 1975 to 1.5 m in 1984, and during the "brown tide" from- 0.5 to 0.7 m (table 14. Salinity values (fig.. 10.1) are of • particular consequence with regard to estimating the input of Meeting House and Terry's Creek to the system. Note that bottom - ebb salinity is frequently slightly (0:5-1.0 ppt) higher than bottom -flood salinity. This suggests a two -layered system where more dense, higher salinity water entering the creeks lags behind surface flow in the deeper entrance channel, and is detected on the ebb tide measurements. Conversely, flooding tide bottom waters reflect the influence (dilution) of the Peconic River water. Like up -river stations a "nutrient -trap" situation exists. Temperature (table V) differences generally indicate the warming effect taking place in the creek waters. Dissolved oxygen values are generally in the 5.0 to 12.0 mg/l range, although in August of 1986 bottom -ebb values dropped to an average value of 1.8 mg/l for 11 samples taken. No fish kill was observed on these occasions. Chlorophyll a means ranged from 3.4 in 1980 to 260 mgm/m3 in 1984, both pre "brown tide" years. 1986-87 chlorophyll a values ranged from 20 to 80 mgm/m3 (table V). H-19 Station P8 Station P8 is located just east of Buoy IN", north of Red Cedar Point, in 3 meters (9-10 feet) of water. When our large research vessels were positioned for twenty-four hour studies, the station was located 1 km (0.6 miles) east in 5-6 meters (16-20 feet). Samples taken during flooding tides here were intended to reflect conditions in Great Peconic Bay, while those during ebbing tides, Flanders Bay. Secchi disc transparency averages (table VII) ranged from 1.7 m in June of 1982 to 0.4 in June of 1984. During the 'brown tide" years, Secchi transparency ranged from 0.3 m in .August of 1986 to 1.9 meters on the flooding tide in June 1987. The pre- and "brown tide" salinity regimen in the entire Peconic system is apparent in Figure 12.1. Pre -brown tide average salinity ranged from a low of 23.74 in June of 1984 to a high of 26.98 in July of 1982. "Brown tide" year average salinities ranged from 25.6 in June of 1987 to a high of 29.07 in August 1986. Similar temperature. and salinity values at surface and bottom indicate complete vertical mixing at this station. This mixing process is reflected in similar surface and bottom dissolver] oxygen values as well. Pre -brown tide D.O. ranged from a low of 4.2 mgm/l in June of 1984 to 8.0 mgm/l in June of 1982. Average Chlorophyll a during the pre -brown tide years ranged at the surface from 1 mgm/m3 in July 1982 to 10 mgm/m3 in June of 1984. Brown tide values ranged from 5 mgm/m3 on the ebb in June of 1987 to 36 mgm/l on the flood in August of 1986 (Table VII). Due to the unusual nutrient spikes during July of 1986, both table VII and figures 12.2 - 12.6 were regrouped for July and August by weekly sampling dates. As was mentioned previously in discussion of nutrient values at stations PR5 and P6, precipitation patterns apparently have a significant effect. This is best demonstrated by figures 12.2 - 12.6. Cn July 13, 1968 1.08 inches of rain fell followed by 1.28 inches on July. 27, 1986 (Cornell H-20 Stations SR to -BIS Figures 1 through 4 in the executive summary illustrate the rationale for grouping Great Peconic to Block Island Sound station data within one dis- cussion section. Not only is vertical mixing within the water column pre- dominant, but also a slight horizontal gradient among all variables is evident from slightly higher (or lower, salinity and secchi•disc-wise) values in the western portions of the system to lowest (or highest) values to the eastern oceanic influenced stations. Tables VIII (MPB - mid Peconic Bay) through XIII (BIS - Block Island Sound), and Figures 13 (Salinity PPB) to 17.1 - 17.6 G.B. - Gardiners Bay illustrate the gradients. BIS, the Block Island Sound station, was .not sampled in the Pre -Brown Tide years. Note that the computer was instructed to vary the y-axis range according to the maximum value at each station. Allowing for this variation in y-axis values is essential to comparing and contrasting the dissolved nutrient graphs for each station (Figures 14-1 through 17-6) . Secchi disc transparencies ranged from less than a meter in the more turbid seas to 5.2 meters at BIS. Chlorophyll a again varied at each station but a distinct pre- and 1985-87 difference is evident. Salinity evidences an almost linear increase from west to east whereas dissolved oxygen varies around the 100% saturation range. Pre- and brown tide year dissolved nitrogen generally remained well below the 5 ugat,/l level as did phosphate phosphorus at all stations east of Great Peconic Bay. H-21 APPENDIX I Hydrogeology Data I.0 GROUNDWATER QUALITY ASSESSMENT Groundwater inflow into the Peconic River and Flanders Bay system was estimated to be 75.6 cubic feet per second through the use of the USGS three dimensional finite model of the aquifer system of Long Island. This estimate does not include inflow of groundwater from the North and South Forks east of Flanders Bay or Shelter Island as this contribution, in terms of flow, is considered to be relatively small. However, the concentrations of nitrogen compounds, organic chemicals and pesticides in the groundwaters of both Forks can be significant and contribute to the loadings going into the Peconic system. This Section characterizes the geology, hydrogeology, groundwater quality, and expected locations of fresh/salt water interfaces of the Peconic system. The impact of loadings from groundwater into the Peconic system may not be as great as the contributions from point sources, surface waters and storm water runoff; however, the groundwater -marine relationship is integral to the understanding and evaluation of the ecological health of the Peconic system. It should be noted that the Brown Tide organism is a marine organism and does not live in groundwater. 1.1 Hydrogeologic Composition of the Peconic System This Section describes the general hydrogeologic conditions on Long Island as they relate to the regional hydrogeology of the Peconic system study area including the Peconic River - Flanders Bay region and the North and South Forks, as well as the Shelter Island region. I.1.1 General Geology Long Island is composed of consolidated tilted basement rocks overlain by unconsolidated sediments that dip in a southeasterly direction. The consolidated rocks, known as bedrock, are dense crystalline metamorphic and igneous rocks of Precambrian age. Overlying the bedrock is a series of unconsolidated deposits that form Long Island's principal aquifers and confining units. During the Cretaceous period, unconsolidated sediments, including sands, silts, gravels and clays, were deposited on the bedrock platform. These deposits were of terrestrial origin acid were probably deposited by prograding shores and coalescing deltas. Cretaceous sediments are divided into two formations: the Raritan Formation, and the Magothy Formation - Matawan Group, undifferentiated. The Raritan Formation is probably a continental coastal plain deposit and is composed of the Lloyd sand member and an overlying unnamed Clay Member (Raritan confining unit) commonly referred to'as the Raritan clay. Above the Raritan Formation lies the Magothy Formation - Matawan Group, undifferentiated, which is composed of continental and shallow marine or deltaic deposits. I-1 In addition, the Monmouth greensand in the Monmouth Group disconformably overlies the Magothy Formation - Matawan Group, undifferentiated. The Monmouth greensand is a marine deposit of late Cretaceous age and underlies most of the southern edge of Suffolk County. With respect to the study area, it is found only along some southern portions of the South Fork. The Monmouth Group is unconformably overlain by Pleistocene deposits consisting of a marine clay known as the Gardiners Clay. The Cretaceous deposits (including the Monmouth greensand along southern portions of the South Fork) are overlain by glacial outwash and morainal deposits of Pleistocene age, as well as Holocene deposits. The Pleistocene formations consist of several glacial, periglacial and interglacial units, including a marine clay known as the Gardiner's Clay, as well as till deposits known as the Montauk Till Member of the Manhasset Formation. The Pleistocene or glacial deposits are believed to have been deposited during the Wisconsin stage of glaciation. This was the last stage of the glacial advance to reach Long Island. Prior to the southward movement/advance of the Pleistocene ice sheets to Long Island, an extensive clay unit, the Gardiners clay, was deposited in shallow marine and brackish waters along the shores of what is now Suffolk County. This unit overlays the Magothy Group and acts as a confining layer 100 to 300 feet thick. The northern portions of the Gardiners Clay were subsequently eroded by advancing -ice and glacial meltwaters, and Gardiners Clay beds are now found only along the south shore. The Pleistocene glaciation created the hilly Ronkonkoma moraine and the Harbor Hill moraine. The Ronkonkoma moraine forms the "spine" of Suffolk County and the South Fork. The Harbor Hill moraine encompasses the north shore and forms the North Fork of Long Island. As the glaciers began to melt and retreat, these deposits (sand, gravel and boulders) were eroded and carried by the melt water, creating extensive outwash plains of sand and gravel in the intermorainal areas and south to the Atlantic Ocean. These highly permeable deposits comprise the upper glacial aquifer and represent the majority of Suffolk's surficial sediments which average 100 to 200 feet thick. In general, the surficial geologic units in the study area consist of Pleistocene (outwash and moraine deposits) and recent or Holocene deposits. Holocene deposits include soil zone. shore, beach and salt -marsh sediments. In addition, in some portions of the study area on the East End 'of Long Island, the Pleistocene deposits consist of till deposits known as the Montauk Till Member of the Manhasset Formation. The Montauk Till Member underlies some of the northern and eastern areas of the South Fork. The unit is discontinuous and appears to be displaced in some areas. It ranges in thickness from 10 feet to more than 50 feet, and contains unsorted deposits of boulders, gravels, sands, silts and clays. Glacial till deposits are also found on Shelter Island and other limited areas on the North Fork. I-2 The chain of bays comprising the Peconic Bay estuary features a convoluted shoreline having numerous necks, islands, bluffs, salt creeks, and marshes. These features are common to a coastal plain estuary formed by the flooding of a river. valley. However, as discussed, the river valley now occupied by the Peconic Bay estuary was formed both by stream erosion and by the action of glacial erosion and deposition. The glacial deposits outwashed from moraines form the substrate of the bays and coastal plains and range from erratic boulders, gravel, and sand, to fine silt and clay. A generalized geologic/hydrogeologic cross section traversing the study area from the north to south is shown in Figure I.1=1. The geologic and hydrogeologic units in the study area, including the Peconic River/Flanders Bay region and the North and South Forks, as well as the Shelter Island region, and their stratigraphic sequence from youngest to oldest rocks and deposits, and water -bearing properties of deposits are summarized in Table I.1-1. The sequence of stratigraphic units in the study area is similar to that found on the main body of Long Island. I.1.2 Peconic River - Flanders Bay Rection The Peconic River - Flanders Bay region is underlain by Pleistocene deposits consisting of terminal moraine and outwash deposits of glacial origin. As discussed, the terminal moraines diverge west of the Peconic River. The Harbor Hill moraine branches to the north and forms hills and bluffs along the North Fork. The Ronkonkoma moraine is found south of the Peconic River and extends along the South Fork. The moraines are composed of till and gravel. Outwash deposits of sand, silt, and some gravel have been deposited between the moraines forming the outwash plains. The Peconic River cuts an east -west channel in the outwash plain discharging into Flanders Bay, and alluvium is deposited along the river. Marsh deposits are found along the bay. The soils are quite permeable, which tends to decrease surface water runoff. Hydrogeologic cross sections in the vicinity of the Peconic River - Flanders Bay region are shown in Figure I.1-3. The locations of these cross sections in relation to the overall study :>area are shown in Figure 1.1-2. As shown in Figure 1.1.-3, the Peconic River - Flanders Bay area is underlain by Pleistocene deposits that form the most shallow hydrogeologic unit, the upper glacial aquifer. These deposits extend -to a depth of approximately 100 feet below sea level where the Magothy Formation - Matawan Group, undifferentiated deposits (and Magothy aquifer) are encountered. The Magothy Formation extends to a depth of approximately 800 feet ( ranging between 700-900 feet) below sea level to the top of the Raritan Clay. The Raritan Clay continues to a depth of about 900 feet (ranging between 800-1.000 feet) below sea level. The Lloyd aquifer extends from approximately 900 to 1,400 feet below sea level until bedrock is encountered.

As discussed previously, this region of Long Island is an extension of the Harbor Hill moraine (along the north shore) which was produced during the advance of the last period of continental glaciation. The study areas in the North Fork region (see Section 1 for study area boundaries) are situated on an outwash plain, south of the Harbor Hill moraine. The topographic features of the area are described'as that of rolling moraines and level to gently sloping outwash plains. As discussed previously, the study areas in the North Fork region are located above unconsolidated deposits of Pleistocene age associated with glacial outwash from the Wisconsin glaciation, as well as Holocene or recent deposits. These deposits overlie the Magothy Formation and an extensive interglacial clay layer. The Pleistocene deposits constitute the upper glacial aquifer and consist primarily of stratified sand and gravel containing very little clay or silt. The Holocene or recent deposits include soil zone, streambed, shore, beach and salt -marsh sediments, as well as fill material. A longitudinal cross section of the North Fork is depicted in Figure I.1-4. As shown in that figure, the contact between upper glacial aquifer and Magothy aquifer deposits varies in depth from about -200 to -430 feet mean sea level (msl). A thick clay layer is found at varying depths and thickness, but is not certain whether the clays encountered are all part of a continuous layer that underlies the entire North Fork, or whether they occur as isolated lenses. The fresh groundwater under the North Fork is believed to exist as a series of four separate, irregularly shaped lenses. The position of the freshwater -saltwater interface, however, has only been measured in a few places and appears to be located at approximately -400 to -450 feet msl near Aquebogue, -250 to -300 feet msl in the vicinity of Cutchogue, -100 to -150 msl near Southold, and possibly -75 to -100 msl in areas located in the vicinity of Greenport and Orient. - The locations of each cross section are shown in Figure I.1-5. Figures I.1-6 and I.1-7 are geologic and hydrogeologic cross sections, respectively, near the center of the North Fork region in the vicinity of Cutchogue. The thickness of Pleistocene deposits and -the upper glacial aquifer above the clay layer varies depending upon the elevations of the .land surface and the top of the clay layer. However, the thickness is estimated to be approximately 150 feet near the center of the Fork, near Well S-71170. The elevation of the top of the clay layer varies throughout the area. but is estimated to be approximately -70 to -120 MSL in the Cutchogue area. The thickness of the clay varies from approximately 40 feet at Well S-71170 to 180 feet at Well S-71279. Groundwater in the upper glacial aquifer is under unconfined (water table) conditions. The water table lies approximately 40-45 feet below the surface at the center of the Fork.

Well S-32390, situated approximately in the middle of the North Fork (see Figure No. I.1- 4), penetrates the Magothy aquifer at a depth of 356 feet. Well S-33775, located 4.5 miles northeast of Well S-32390, penetrates the Magothy at a depth of 205 feet. In addition, Well S- 68831 penetrates the Magothy at a depth of 205 feet below ground surface. Little detailed data are available at the present time on the vertical extent and water quality of the Magothy aquifer on the North Fork; however, groundwater is believed to be salty in a large portion of this aquifer. The exact position and thickness of the zone of diffusion and the movement of the saltwater is not clearly defined. As shown in Figure I.1-7, the freshwater -saltwater interface appears to occur at approximately -320 to -330 feet MSL at the center of the Fork in the vicinity of Well S-71170. Cores from Well S-32390 located southwest of Well S-71170 showed the interface to be at about -290 feet MSL. Thus, there may be some fresh water below the clay layer (below -228 feet MSL) at the center of the Fork near Well S-71170, but the quantities would be extremely limited (if anv) in this area. I.1.4 South Fork Region The South Fork is underlain by unconsolidated deposits composed of Cretaceous and Pleistocene sediments that rest on Precambrian - Upper Paleozoic basement complexes or bedrock. The Cretaceous deposits include (in ascending order): the Raritan Formation, which consists of the Lloyd Sand Member (Lloyd aquifer) and an overlying clay member -(Raritan clay); the Magothy Formation - Matawan Group, undifferentiated; and the Monmouth Group. The Cretaceous deposits are overlain by Pleistocene deposits consisting of the Gardiners Clay, the Montauk Till Member. of the Manhasset Formation, the Ronkonkoma drift, and loess. The surficial geologic units are composed of Pleistocene and Holocene or Recent deposits. The Pleistocene sediments consist of Late Wisconsin glacial and glaciofluvial deposits, and the Holocene deposits consist of beach and marsh sediments. The Montauk Till Member (Manhasset Formation) underlies some of the northern and eastern areas of the South Fork. This unit is discontinuous and appears to be displaces( in some areas. Glacial till deposits are also found on Shelter Island and limited areas of the North Fork. As discussed previously, 'the Ronkonkoma moraine, created by Pleistocene glaciation, extends along the South Fork. In the portions of the study area on the South Fork, north of the Ronkonkoma moraine along the northern portion of the South Fork, are morainal and till deposits, as well as shore, beach and salt -marsh deposits along coastal areas of the bays. South of the moraine are outwash deposits and more extensive shore, beach and salt -marsh deposits I-13 along coastal areas of the ocean. The moraine is composed of till and gravel. The outwash deposits consist of stratified, fine to coarse sand with some fine to medium gravel. Several hydrogeologic cross sections through the South Fork are shown in Figures I.1-9, I.1-10, and I.1-11. The locations of the following South Fork cross sections are shown with respect to the study area in Figure I.1-8. The outwash deposits form the upper glacial aquifer. As shown in Figure 1.1-9, the outwash deposits and upper glacial aquifer varies in thickness from approximately 150-200 feet, and the upper glacial overlies the Magothy aquifer, which is found at approximately -200 feet msl (between -150 and -250 msl). The Magothy aquifer is a water bearing unit of sands, silts and clays, with some thick clay beds. Figure I.1-12 is a longitudinal cross section depicting the freshwater/saltwater interface below the South Fork. Fresh groundwater under the South Fork exists as a lens overlying salty groundwater. The depth of the freshwater/saltwater interface varies in direct proportion to the height of the water table above sea level. On the southern half of the South Fork, the depth of the interface is approximately 40 feet below sea level for each foot the water table is above sea level. On the norther half of the South Fork, the interface is found at lesser depths due to the anisotropy (layering) of the aquifer material. The zone of the diffusion that comprises the interface is generally narrow, ranging from .20 to 60 feet. I.1.5 Shelter Island The major geologic units on the North Fork and Shelter Island have been described previously in this Section. All surface strata within the' Shelter Island region study area are of Pleistocene 'age or younger. Shelter Island's surficial geologic units consist of Pleistocene deposits of poorly to moderately sorted stratified glacial drift that are underlain. by Pleistocene clay units. This stratified drift forms the upper glacial aquifer which is Shelter Island's sole source of fresh water. Fine to coarse sand is.predominate, but particle size ranges from clay to boulders. Areas of topographic peaks, such as the northwestern part of the island, have abundant silt and clay deposits. The location of a hydrogeologic cross section of Shelter Island is shown in Figure I.1-13. The hydrogeologic cross section of Shelter Island is depicted in Figure 1.1-14. The stratified drift unit ranges in thickness from approximately 85 to 140 feet. The stratified drift is underlain by a 50 to 100 feet of Pleistocene marine clay that is comprised of gray -green and dark gray clay deposits. This marine clay unit is in turn underlain, in intermittent areas, by a Pleistocene nonnmarine clay unit (greater than 100.feet in thickness) consisting of brown and reddish -brown outwash deposits. Subsurface geologic units consist of Cretaceous deposits and bedrock. The Cretaceous deposits consist of Magothy Formation - the Matawan Group, and the Clay (Raritan) Member I-14 LONG ISLAND SOUND � RIVER Ln Fee BP,..4 1 w600 FLANDERS BAY 1~ a, s LNTLE I PECONIC BAY T A GREA P£CON/C !EA Y C� BLOCK ISLAND SOUND ARDIN£R S i T ND ear E REp�,pN D \ ��0� co Do LEGEND O B' LOCATION OF GEOLOGIC CROSS—SECTION At /pN AAjN� LOCATIONS OF SOUTH FORK HYDROGEOLOGIC CROSS SECTIONS 1� FIGURE 1.1 - 8 v Mp 70M M .I SOURCE: USGS, WSP-2073 LM ■ SOUTH FORK HYDROGEOLOGIC CROSS SECTION A - A' I-16 EXPLANATION II Sand and gravel Sand I I — Sand, silt, and day Clay II Lignite Shells G—Gama ray log ll E—Electric log II FIGURE 1.1 - 911 B ...............

These deposits form the hydrogeologic unit known as the Magothy aquifer. A well near the center of the island penetrated the Magothy Formation approximately 345 feet below land surface. A generalized hydrogeologic section showing the approximate depths and thickness of each hydrogeologic unit is shown in Figure I.1-15. An erosional unconformity separates the Magothy Formation from the Raritan Formation. The upper, Raritan Clay Member consists primarily of clay, silty clay, and silty fine sand, with beds and lenses of lignite, pyrite and gravel. The lower, Lloyd Sand Member is composed of fire to coarse sand and gravel, with beds and lenses, of clay, silty sand, lignite, and pyrite. These units comprise the hydrogeologic formations known as the Raritan Clay and the Lloyd Aquifer, respectively. The crystalline bedrock, believed to be Precambrian, is composed of gneiss and schist. It is found at a depth of approximately 790-880 feet below sea level. Table I.1-2 presents a breakdown of the geologic and hydrogeologic units found in Shelter Island. I.1.6 Groundwater - General On Long Island, groundwater exists mainly in three aquifers composed of unconsolidated sandy sediments deposited by glaciers. Groundwater is used extensively on. -Long Island for drinking and for agricultural and industrial use. It is essential that groundwater quantity and quality be protected, since contaminants from septic tank effluent, landfill leachate, hazardous chemical spills, pesticides, �as well as saltwater,, can potentially enter the aquifers and render them unsafe for human or agricultural use. As previously discussed in Section I. L the geologic units present in the Peconic system study area (including the Peconic River - Flanders Bay region, the North and South Fork regions and the Shelter Island region) comprise several hydrogeologic units. The more recent Pleistocene deposits constitute the upper glacial aquifer. The Magothy Formation - Matawan group. undifferentiated of Late Cretaceous origin, forms the Magothy aquifer. The Lloyd Sand Member of the Raritan Formation, also of the Late Cretaceous age, forms the Lloyd aquifer. The Clay Member of the Raritan Formation. referred to as the Raritan Clay, acts as a relatively impenneable confining layer separating the Lloyd aquifer from the Magothy aquifer. The upper glacial aquifer is the major source of water supply for both the North and South Forks, since the Magothy aquifer generally becomes salty eastward on the Forks. The locations of hydrogeologic cross sections through four portions of the study area are depicted in Figure 1.1-16. The cross sections are shown in Figure I.1-17. The upper portion of the groundwater reservoir is freshwater which originates from local precipitation; the deeper groundwater is saline. The water table elevation ranges from sea level I-22 MONMOUTH GENERALIZED HYDROGEOLOGIC SECTION FIGURE 1.1 - 15 I SOURCE: SCDHS, 1987 THROUGH THE EAST END OF LONG ISLAND 'TABLE 1.1 — 2 STRATIGRAPHY AND HYDROGEOLOGIC UNITS OF SHELTER ISLAND Source: Suffolk County Planning Commission, 1986 Approximate Depth System Series Geologic Unit HYdrogeologic Unit Thickness (ft.) ft.

L.. 1 to 40 feet msl on the South Fork. The water table elevation is approximately 45 feet above mean sea level in the western portion of the study area in the area of headwaters of the Peconic River. Precipitation averages 45 inches annually, and approximately half of this is estimated to recharge the fresh groundwater reservoir. - The balance is accounted for by overland runoff and evapotranspiration. The recharge of approximately 22 inches is equivalent to an average rate of approximately one million gallons per day per square mile. The study area is bounded by the groundwater divide. On the North Fork the study area lies to the south of the divide. Recharged groundwater moves through the aquifers south to the Flanders, Peconic and Gardiners Bays. The South Fork portion of the study area lies to the north of the divide, resulting in northward movement of groundwater to the aforementioned surface water bodies. The groundwater divides along the North and South Forks meet just west of the headwaters of the Peconic River. In recent years, the United States Geological Survey (USGS) has developed a three dimensional finite difference model of the Long Island aquifer system. Using this model, the USGS has estimated the fresh water flow into Flanders Bay to be approximately 50 million gallons per day; 71% is stream flow into the bay, and the remaining 29% is groundwater flow directly into the bay. In addition, the USGS has determined that for the land area east of Flanders Bay, along the North and South Forks, the groundwater systems are independent from the regional system. The USGS believes these areas contribute only a small amount of fresh water to the remainder of the Peconic system. I.1.7 Peconic River - Flanders Bay Region: Groundwater Occurrence and Flow/Movement Regional groundwater flow in the Peconic River/Flanders Bay region is shown in Figure 1.1-18 of water table contours of the region during March 1989. The horizontal component to groundwater flow is shown in the regional water table map, whereby the direction of groundwater flow is generally perpendicular to the water table elevation contour lines. As can be noted, the regional shallow groundwater flow in the water table is to the Peconic River and Flanders Bay. Long Island's major groundwater divide, which traverses the island from west to east, splits near Riverhead into a north branch extending into the North Fork and a south branch extending into the South Fork. Groundwater north of the divide moves northward to Long Island sound, and groundwater south of the divide moves southward to Great South Bay and Moriches Bay, either directly or by way of streams. In general, groundwater from the area between the two branches of the divide within the Peconic River - Flanders Bay region study area moves eastward to the Peconic River and Peconic Bay system. This divide is not stationary but moves north or south as the water table configuration changes. These changes I-27 r --r N 00 0 . ..... =.: .o � °na ve �---�--! \ � °r.r.. °,.,r, RIV�RHEAD• i . /J - t o H. hen i 1 y.o. o p Nal • ..,o o„»r'' Sr `\ '1 GREAT PE /�� '• o r .00r;� \_� �.� .,;�.

Seasonal fluctuations in water levels at the divide are usually less than 5 feet. The groundwater divides are utilized as the study area boundaries. In the westernmost portion of the study area, an additional area of.influence which contributes groundwater to the Peconic River has been delineated. This is the area in which the shallow flow groundwater regime reaches the surface waters of the Peconic River and its tributaries. Thus, the study area consists of the groundwater -contributing area to the Peconic and.to the Flanders/Peconic Bays system. The deeper recharge aquifers in the Peconic River groundwater -contributing area, although flowing towards the river and Peconic estuary,, have a vertical component of flow which precludes a direct impact on the surface waters of the river system. The time scale for deep flow area9 to impact on surface waters in this region is locally variable and is not known with precise certainty; however, the time range is estimated to be on the order of centuries. In addition. the Magothy aquifer is generally beyond the most environmentally sensitive waters of the study area. Therefore, for planning purposes, the groundwater -contributing area to the Peconic River has received special attention with respect to land use and pollutant loading analysis. East of CR 105,'the groundwater -contributing area to Flanders Bay has been divided into a near -shore and an inland influence. The rationale for this separation is that the areas near the shore have a more direct and immediate impact on the surface water system, while groundwater in areas further inland may take decades or centuries to reach the bays. The northern boundary of the North Fork system study area is the northern branch of the groundwater divide from CR 105 in the Town of Riverhead to Orient Point in the Town of Southold. The southern boundary of the South Fork study area is the groundwater divide from CR 104. The eastern boundary of the study area is western Block Island Sound, from Orient Point southeast to Montauk Point. Groundwater is recharged by infiltration of precipitation through the surficial deposits to the water table. The quantity of water that reaches the water table varies throughout the year. Several factors control the amount of recharge; these include variations in precipitation. the stratigraphy and soil characteristics of the area. and the rate of evapotranspiration. Under natural conditions, the only source of water to the Peconic River - Flanders Bay region groundwater system is recharge from precipitation. Approximately half the precipitation that reaches the land surface infiltrates and enters the groundwater system at the water table. Some of this water flows in a shallow flow subsystem and discharges to streams or lakes in the Peconic River basin. Water that enters the system near Flanders Bay flows through the upper glacial aquifer and discharges to the bay. Water that enters the system further inland flows down I-29 to the deeper aquifers. Water near the major groundwater divide flows downward to the Lloyd aquifer. Groundwater is discharged naturally as seepage to streams in the study area and also into the Peconic River basin. Groundwater also discharges directly into Flanders Bay along the shore. The groundwater contributing area around the upper reaches of the Peconic River is difficult to delineate because this area has poor drainage and many small ponds and swamps, and thus contributes little base flow to the Peconic River. Discharge in the upper reaches averaged 3 cu. ft/s: that in the downstream reaches averages 30 cu. ft/s (Warren et al., 1968). It is therefore probable that the main groundwater contributing area is around the downstream reaches of the Peconic River. Groundwater Quantity and Use Groundwater is the only source of water supply for the area. A majority of the water in the Peconic River - Flanders Bay region is obtained from the upper glacial (water table) aquifer. Tlie remaining water is obtained from the Magothy and Lloyd (deep) aquifers. At present, Suffolk County Water Authority supplies the majority of the water in the area. Other water is supplied by several smaller companies. j The total public water supply withdrawal in the area in 1982 was estimated to have been approximately 9.1 million gallons per day (MGD). In 1982 approximately 7.9 MGD was withdrawn from the upper glacial aquifer and 1.0 MGD was withdrawn from the Magothy aquifer. Groundwater is also used for irrigation. Pumpage for farm and golf course irrigation is unknown but is estimated to be less than 0.5 MGD and is pumped solely from the upper glacial aquifer. Both the upper glacial and Magothy aquifers are capable of producing considerably more water than is currently being withdrawn. Use of the Lloyd aquifer is legally restricted. 1.1.8 North Fork Region: Groundwater Occurrence and Flow/Movement The major water bearing geologic units on the North Fork are the Pleistocene deposits (glacial deposits including the upper glacial aquifer) and the Magothy Formation - Matawan Group (Magothy' aquifer). The primary groundwater aquifer on the North Fork, is the upper glacial or water table aquifer. The saturated thickness of this aquifer ranges from approximately 50 to 200 feet. Most wells drawing freshwater from these permeable deposits are between 10 and 100 feet deep, and extend about 10 to 35 feet below MSL. I=30 Regional groundwater flow on the North Fork is shown in Figure I.1-19 of water table contours of the entire North Fork for March 1989. Groundwater elevations are highest near the center of the Fork and lowest near the shoreline. The horizontal component to groundwater flow is shown in the regional water table contour map, whereby the direction of groundwater flow is generally perpendicular to the water table elevation contour lines. As shown in Figure I.1-19, regional groundwater flow is separated into north and south groundwater flow regimes by the groundwater divide that runs northeast and southwest across generally the center of the North Fork. Flow moves outward from the central groundwater divide toward either shoreline (northward toward Long Island Sound and southward toward Flanders Bay, Great Peconic Bay, Little Peconic Bay and Gardiners Bay). Near the center of the divide, downward, nearly vertical flow and recharge of groundwater occurs (with velocities of approximately 0.1 ft./day). While moving north or south away from the divide, the flow becomes increasingly horizontal (with velocities of 0.2 to 0.4 ft./day) until groundwater discharge occurs at the shorelines. Within approximately 1/4 mile of the shoreline, the vertical component of flow is upward as groundwater is influenced by the boundary effects of the saltwater interface and is discharged via seepage and underflow to surface waters. Figure I.1-20 shows the groundwater flow patterns near the center of the North Fork in the Cutchogue area. As previously discussed in Section 1.1, below the upper glacial aquifer is an extensive interglacial clay layer and the Magothy aquifer, the upper surface of which varies from 100 to 150 feet below sea level near the center of the North Fork in the vicinity of Cutchogue station. The complete areal extent of the clay, the depositional environment and its relationship to other clays on Long Island (i.e., the Gardiners Clay, the 20 foot clay, and the Smithtown Clay) remain to be determined. This clay unit has the ability to inhibit the upconing of saltwater beneath high yield supply wells. Separating the Magothy from the underlying Lloyd aquifer is a semipermeable layer of Raritan clay which somewhat inhibits the vertical flow of water from the Magothy to the Lloyd aquifer. The Magothy (in general) and Lloyd aquifers in this area are not usable for potable water purposes because of saline conditions. The entire North Fork is located in Hydrogeologic Zone IV, as defined in the Long Island 208 Plan. Zone IV is characterized by generally shallow, horizontal groundwater flow and groundwater discharge near the shorelines. Zone IV was described in the 208 Plan as an area that has local water quality problems with significant agricultural input, but has potential for groundwater development.

The configurations of the fresh water lenses are in equilibrium with the saltwater that surrounds them. Their thickness and lateral extent remains stable over time because of the balance between recharge and discharge. The location of the fresh water - saltwater interface, the boundary between the fresh water lenses and the underlying saltwater - also tends to remain unchanged as long as the aquifer is not overpumped. As discussed in Section I.1, the position of the interface has been determined in a few places and appears to be located at approximately 400 to 450 feet below mean sea level (insl) in areas located near Aquebogue, -250 to -300 feet msl in the vicinity of Cutchogue, -100 to -150 msl near Southold, and possibly -75 to -100 msl near Greenport and Orient. This information, in conjunction with estimates based on the Ghyben-Herzberg principle, were used to locate the position of the interface on an east -west longitudinal cross section of the study area (see Figure 1.1-4). The Ghyben-Herzberg relationship states that the distribution of fresh and saltwater at hydrostatic equilibrium is caused by the difference in density between fresh and saltwater. Based on this difference, the depth of fresh water below sea level is predicted to be 40 times the height of fresh water above sea level. The relationship is theoretical and when applied to the North Fork consistently underestimates the actual depth of available fresh water. The position of the interface deviates from predicted locations in some areas because of lithology. The interface is found below the clay unit, and in many areas this is much deeper than would be expected. The thick, relatively impermeable clay unit apparently prevents the interface or the associated zone of diffusion from responding to short-term fluctuations of the water table. The lateral position of the interface is not influenced by the clay. There is no comparable barrier to check the horizontal, landward encroachment of saltwater. Groundwater withdrawals near the shoreline, over a prolonged period of reduced recharge, could have an effect on the position of the interface with respect to the shoreline. Groundwater Quantity and Use The principal water supply source in the study area is the upper glacial aquifer. It is a highly productive water -bearing unit with consistent physical properties. On the North Fork, east of Mattituck Creek, a very delicate balance exists between fresh groundwater lenses, saltwater intrusion, chemical contamination and water supply requirements. The fresh groundwater lenses are relatively thin; therefore, the total available supply is limited. Overpumping or improper well location causes lateral and vertical saltwater intrusion. The aquifers are extremely susceptible to I-34 chemical contamination because they are shallow and have limited dilution or assimilative capacity. Groundwater flow velocities are very low (on the order of one foot per day) so it takes long periods of time for contaminants to flush out. of the aquifer (up to 100 years). These conditions mandate that groundwater resources be properly managed and protected in order to be able to support necessary water supply requirements. Consumptive water use patterns are expected to change in the study area over the next 20 years. The study area includes portions of the North Fork from Orient westward to the -area north of the point where the Peconic River discharges to Flanders Bay (Aquebogue area). Domestic requirements (including commercial and industrial) are expected to be approximately 3 million gallons per day (MGD) while agricultural consumptive use is expected to be .approximately 6 MGD in the year 2000. The trend to residential development from agriculture will result in a slight overall decline in average daily water use, but the demand for uncontaminated, potable water will increase (ERM, 1983). The permissive sustained yield for the area was calculated to he 11.8 MGD; safe yield in Nassau/Suffolk Counties has been defined as "the quantity of groundwater that can be removed frotn the system and used consumptively on an annual basis without producing undesirable results" (LIRPB, 1978). While "permissive yield" is often used interchangeably with safe yield (as in the BTCAMP report), it implies more of a regulatory ;►pproach and could be replaced by "safe yield" in this report. . , The hydraulic conductivity of the upper glacial aquifer ranges from a regional North Fork estimate of 2,000 gallons per day per square foot (gpd/sq ft) to approximately 3,000 gpd/sq ft in Cutchogue and Southold, to 4400 gpd/sq £t in Jamesport. Specific capacities ranged from approximately 9.5 gallons per minute per foot (gpm/ft) in Aquebogue, to 30 gpm/ft in Cutchogue and Southold, to 58 and 68 gpm/ft in the Village of Southold and Jamesport, respectively. Transmissivities of the upper, glacial aquifer ranged from 223,000 and 267,000 gpd/ft in Southold and Cutchogue, respectively to 380,000 gpd/ft in Jamesport (ERM Northeast and CDM, 1983). 1. 1.9 South Fork Region: Groundwater Occurrence and Flow/Movement The major water bearing geologic and hydrogeologic units on the South Fork are Pleistocene deposits or glacial deposits, forming the upper glacial aquifer, and Cretaceous sediments of the Magothy Formation - Matawan Group, forming the Magothy aquifer. The upper glacial is the major course of water supply for the South Fork. It generally corresponds to the saturated upper portion of the highly permeable Pleistocene deposits.. The configuration of the water table is controlled by the thickness and water -transmitting. properties of the aquifer, the water transmitting properties of the underlying deposits, by the amount and location of recharge, and by the location and nature of natural discharge points (streams, etc.). I-35 - Depth to the water table generally increases northward from near zero feet along the south shore to more than 100 feet beneath parts of the Ronkonkoma moraine along the northern portion of the South Fork. From the Ronkonkoma moraine, depth to the water table decreases northward to near zero at the north shore of the Fork. Regional groundwater flow on the South Fork is shown in Figure I.1-21 of water table contours of the entire South Fork during March 1989. As mentioned above, groundwater elevations are highest below the moraine deposits along the northern portions of the Fork and lowest near the shoreline. The horizontal component to groundwater flow is shown in the regional water table map, whereby the direction of groundwater flow is generally perpendicular to the water table elevation contour lines. As shown, regional groundwater flow is separated into north and south groundwater flow regimes by the groundwater divide that nuns generally west to east across the center of the South Fork. Flow moves outward from the central groundwater divide toward either shoreline (northward toward Flanders Bay, Great Peconic Bay, Little Peconic Bay, Gardiners Bay and Block Island Sound). Near the center of the divide, nearly vertical flow and recharge of groundwater occurs. North or south away from the divide, the flow becomes increasingly horizontal until groundwater discharge occurs at the shorelines. The movement of groundwater froth inland areas to the shore is fairly slow, on the order to 0.5 feet per day. Near the shoreline, the vertical component of flow is upward as groundwater is influenced by boundary effects of the saltwater interface and is discharged via seepage and underflow to surface waters. The lower boundary of the freshwater -bearing zone of the upper glacial aquifer near the shore is the freshwater -saltwater interface and, further inland, it is the top of the Magothy aquifer. The approximate thickness of the freshwater -bearing zone -in the upper glacial aquifer varies widely across the South Fork and ranges from zero near the shores to approximately 250 feet near the center of the South Fork. Where the Gardiners clay is present in the freshwater zone, it delineates the lower boundary of the upper glacial aquifer. The Magothy aquifer is the deepest freshwater -bearing zone on the South Fork. In some areas on the South Fork, the upper portion is in direct contact with the upper glacial aquifer and is under water -table conditions. However, in most areas the Magothy aquifer is overlain by units of lower permeability and is under artesian conditions. Confined aquifers, also known as artesian aquifers, occur where groundwater is confined under pressure greater than atmospheric by overlying, relatively impenneable strata. In limited areas on the North Fork, portions of the magoth_v aquifer are overlain by a confining bed of clay, resulting in artesian conditions. The upper boundary of the freshwater -bearing zone of the Magothy aquifer is the base of the upper glacial aquifer. The lower limit is the freshwater -saltwater interface.

No data on the South Fork part of the Lloyd aquifer is available. No wells have penetrated the full thickness of the Lloyd aquifer, but it is assumed to underlie the entire study area. Since in all parts of the South Fork, saltwater extends into the Magothy aquifer and, in many areas, into the upper glacial, it is improbable that the Lloyd contains freshwater. Therefore, it is not considered a potential freshwater supply. Groundwater Quantity and Use Groundwater is the only source of water supply to the residents of the South Fork. Most of the water is obtained from the upper glacial (water table) aquifer and the remainder is obtained from the Magothy aquifer. The average horizontal hydraulic conductivities of the upper glacial and Magothy aquifers are estimated to be 350 ft/day and: 70 ft/day, respectively. The transmissivity of the upper glacial aquifer ranges from 5,350 sq ft/day to 22,725 sq ft/day. The transmissivity of the Magothy aquifer ranges from 607 sq ft/day to 24,064 sq ft/day. Total public -supply pumpage on the South Fork was estimated to be approximately 3 - MGD. Public -supply withdrawals in 1976 averaged 2.75 MGD; of this amount, 2.55 MGD was withdrawn from the upper glacial aquifer, and 0.17 MGD from the Magothy aquifer. These aquifers are capable of producing larger quantities of water than are currently being withdrawn. I.1.10 Shelter Island Region: Groundwater Occurrence and Flow Movement Shelter Island's surficial geologic units consist of Pleistocene deposits of stratified glacial drift that are underlain by clay units. This stratified glacial drift forms the upper glacial aquifer which is Shelter Island's sole source of fresh water. The stratified drift deposits of the upper glacial aquifer range in thickness from approximately 85-140 feet. Water levels in the upper glacial (water table) aquifer have remained unchanged (in equilibrium) over the last several decades, except for local cones of depression around pumping centers. The water level contours of the water table on Shelter Island generally reflect the island's topography, and the water table is high beneath topographic highs such as the Shelter Island Heights and Dering Harbor areas. Water levels fluctuate with seasonal changes and long- term variations in precipitation. Water table contour snaps, based on readings recorded in monitoring wells from 1974 to the present by the SCDHS Bureau of Water Resources, reveal that during low recharge periods the maximum freshwater contour line on Shelter Island is only 2 ft above mean sea level. Figure I.1-22 shows how the maximum water table contour in the central I-38 80URCE:3UFFOLK COUNTY PLANNING COMMISSION,MARCH 1986 MARCH, 1986 .•'� �oh, O ,,�♦ o�• I o p,•.0 OP Sol 0 w 80 oil S �ofot o o,ro,o rt• o ,, o j•, I,0 _ � 441 0 req 1 j i o f '�.i•do j j ® j • ,1 tip `dp SHELTER ISLAND WATER TABLE CONTOUR MAPS MARCH,1984 & MARCH, 1985 FIQURE. 1.1 — 22 portion of the island dropped from 7 ft in 1984 to 3 ft in 1985 due to the onset of drought conditions. Shelter Island's groundwater level elevation continually shifts due to fluctuating precipitation levels. The water table contour map of Shelter Island for March 1989 is shown in Figure I.1-23. Fresh groundwater on Shelter Island continually flows from the high areas of the water table toward the perimeter of the island where it discharges to the surrounding saline water bodies. The Magothy aquifer was intercepted at approximately 300 feet below mean sea level on Shelter Island. There are no production wells tapping the Magothy aquifer. This is mainly because it is believed that groundwater is salty throughout this aquifer (as well as deeper formations). This belief has been substantiated by tests indicating extremely high chloride concentrations at the top of the Magothy. The exact position and thickness of the zone of diffusion and the movement of the saltwater interface have not been adequately defined. Freshwater -Saltwater Interface Previous studies have concluded that the position of the freshwater -saltwater interface is roughly in accordance with the Ghyben-Herzberg principle. This principle states that, under static conditions, the depth of the interface below sea level will be approximately 40 times the elevation of the water table above sea level. As indicated previously in Section I.1, Figure I.1-13 is a cross-section through Shelter Island showing the approximate position of the saltwater/freshwater interface (the chloride concentration of 26 ppm was used as a boundary). Test data indicate that the marine clay unit apparently retards upward movement of salty groundwater. Thus, the top of the clay marks the bottom of the freshwater zone. Groundwater Quantity and Use All of the groundwater utilized in the Town is obtained from the upper glacial aquifer. The Upper Pleistocene glacial sediments in this aquifer are a productive source of fresh groundwater on Shelter island. The Magothy aquifer is not utilized and it is believed that groundwater is salty in this aquifer. Most groundwater pumped on Shelter Island is for domestic use. The average daily pumpage in Shelter Island, by land use category, is presented in Table I.1-3. The total groundwater pumpage rate (water demand) is projected to increase by approximately 50 percent from 0.4 MGD to 0.6 MGD by the year 2020. The permissive sustained yield for Shelter Island was estimated at 2.0 MGD (Holzmacher, et all. 1970). Residential pumpage projections were made by utilizing the 1980 pumpage rates as a baseline, and estimating the incremental changes for subsequent years by using population I-40 LF , �► 301182 ` `75435 ' 501181 2084 O 38463 ; • i 8� 4 I'o` Z, 051180 i 051171 05 1176 0 3 7543 O / 51175 51 79 51169 52050 7'5432 p O O ` Q511 2 O / 8461 �%051 178 i .0 '♦_ 110 H EL _ 75440 ` 75439 51177 075441 0 , ` 51183 i O % e ' LEGEND / O 51177 OBSERVATION WELL AND WELL NUMBER , ego too %) 5 — WATER TABLE CONTOUR INTERVAL 0 0.5 1 SHELTER ISLAND WATER TABLE CONTOUR MAP SOURCE: SCDHS, 1989 MARCH. 1989 FIGURE 1.1 - 2311 I-41 TABLE_ 1.1 — 3 AVERAGE DAILY PUMPAGE (MGD) BY LAND USE CATEGORY FOR THE TOWN OF SHELTER ISLAND Land Use 1980 2000 2020 Residential 0.3 0.4 0.5 Commercial/Industrial * * 0.1 Agricultural 0.1 Institutional Cemetery/Golf Course Total Town of Shelter Island 0.4 0.4 0.6 Total Suffolk County 207.6 229.7 244.0 Note:* Less than 0.05 MGD Source: Suffolk County Department of Health Services, 1987 I-42 projections. The commercial/industrial, institutional, and cemetery/golf course projections were made by using the same baseline as applied to land use projections. Test wells drilled on Shelter Island exhibited yields of 4 to 130 gpm and specific capacities of 0.5 to 30 gpm/ft (Woodward -Clyde, 1977). These values are lower than expected because of the relatively small diameter and length of screen of the wells tested; also, the values obtained have not been corrected for partial penetration. Data for the upper glacial/water table aquifer on Shelter Island were insufficient to permit reliable estimates of storage (i.e., the volume of water present in the upper glacial/water table aquifer on Shelter Island, where the existing USGS data base does not provide a reliable volume estimate). As mentioned above, the permissive sustained yield for Shelter Island was calculated to'be 2.0 MGD. Shelter Island's groundwater generally meets federal and state drinking water standards. According to the U.S.G.S. Report 85-4165, the fresh groundwater is of good quality, except near the shore. Average chloride concentrations occurred in wells located near the shore. "Average chloride concentrations" reflect samples showing 20mg/1 at wells located at Dering Harbor, Little Ram Island, and Menantic Road. However, the chloride concentrations at these three wells are subject to rapid fluctuations in response to seasonal changes in pumpage and recharge rates. Please refer to USGS Report 85-4165 for further information. Generally, those wells located suid pumped in or near the zone of diffusion (fresh water/salt water interface) will yield excessive concentrations of chlorides, especially during late summer and early fall. This is the dry season and peak water consumption period for the island. However, as pumping is reduced, chloride concentrations will decrease. The Suffolk County Planning Commission, March 1986, reported that the average nitrate nitrogen concentration in the wells samples on Shelter Island was 3.7 mg/l. Four of the 35 wells samples exceeded the standard (10 mg/1) for nitrates. Nitrates in the groundwater of Shelter Island are associated with on-site sanitary systems and fertilizer use. In the developed areas, septic tanks and cesspools are the likely causes of excessive nitrates; in cultivated and agricultural areas, fertilizers are the likely sources. Three of the wells sampled exceeded the standard for synthetic organics. . The VOCs detected in the groundwater included benzene, toluene and Ortho. In all three cases, contamination was limited to specific sites and appears to be the result of accidental spillage. No other VOCs or pesticides were detected in the groundwater. Thirty-three percent of the well samples on shelter Island exceeded the standard for iron. Although excessive iron concentrations are not hazardous to health, they cause staining (►f clothing and surfaces that are in contact with the water.

GAFFNEY SUFFOLK COUNTY EXECUTIVE MARY E. HIBBERO. M.D.. M.P.H. COMMISSIONER ENVIRONMENTAL REVIEW WASTEWATER TREATMENT AND TOXIC MATERIALS STORAGE BROOKHAVEN NATIONAL LABORATORY UPTON, NEW YORK ■ FARMINGVILLE. NEW YORK 1 1 738-1 220 K-1 ■ (5161654-25 FAX ■ 654-28.05 INTRODUCTION Brookhaven National Laboratory is a federally -funded research facility that operates in Upton, New York. This review examined the wastewater handling practices at the facility, as well as the storage of toxic or hazardous materials. What follows reflects the results of the department's investigation. WASTEWATER TREATMENT Sanitary wastes from the majority of buildings at the facil.it.y are discharged into a collection system consisting of 18 pump stations and gravity sewers. This waste is conveyed to a sewage treatment plant for processing. Effluent from the sewage treatment plant is discharged, under New York State Pollutant Discharge Elimination System (SPDES) Permit #NY -0005835, to a creek on the facility property which, in turn, discharges to the Peconic River. INDUSTRIAL WASTE PRETREATMENT At the present time, there is no industrial pretreatment of waste performed at the facility; however, all photo processing wastes generated at the laboratory are held and hauled away by a licensed waste scavenger. The facility is currently researching the feasibility of installing pretreatment on the photo waste, primarily silver recovery, and discharging this waste into Lhe sewage treatment plant. SEWAGE TREATMENT PLANT The wastewater is conveyed to the sewage treatment placit via the collection system. Approximately two hours prior to arriving al_ the.plant, the wastewater is analyzed by automated systems, at. manhole 199, for concentrations of pH, conductivity, aiid radioactivity. If any of these are in excess of standards, aii alarm condition is sounded at the plant and the operator is automatically informed. The wastewater is then by-passed, either manually by the operator, or automatically, in case of lack of operator intervention, to one of two lined holding ponds. At �1 later time, the water within these ponds is treated as required and pumped to the head of the treatment plant for processing. As the liquid enters the plant, it flows through o►ie of t.wn barminutors/grit chambers for the removal of large solids within the wastestream. At this point, chlorine is added to the: sy9t_em to help control bacterial growth within the process. The liqui(i then flows through a manhole to a primary clarifier. TipiS manhole is used to manually divert the flow to the lined riold.i iicj ponds and the clarifier serves to remove suspended particulat­� matter from the wastewater. Sludge collected at. the bottom (-)f the clarifier tank is conveyed to the sludge digester where i.t K-2 undergoes anaerobic digestion. The liquid continues Lhrough Llm automatic by-pass manhole to sand filter beds. Twelve beds cru: utilized on a rotating basis, - via dosing siphons, for still further reduction of solids. The filter beds' effluent: is collected via an underdrain system and discharged to a creek on the property and subsequently 'the Peconic River. At the requesL of the New York State Department of Environmental Conservation, post -chlorination of the wastewater was -terminated in 1983 due to, the fact that elevated levels of coliforms were historically absent from the effluent. At the point of discharge, the effluent is ,sampled for pH, flaw, radioactivity, dissolved oxygen, and conductivity. In addition, the laboratory is experimenting. with a.Volatile Organic Compounds (VOCs) meter to monitor the presence of VOCs within Llie wastestream. In the near future, analysis for benzene; 1,1,1 trichloroethane; methylene chloride and chloroform will he performed on a continuous basis, as well as analysis for other VOCs of possible concern. An'inspection of the facility was performed on May 5, 1992, during which all plant equipment was found to be in satisfactory operating condition. It was learned, through conversations with lal?oratory personnel, that $4,000,000 of sewer reliabilitat.ioll work is planned to commence this year and another $4,000,000 for upgrading the sewage treatment. plant is scheduled to be appropriated next year. At this point in time, preliminary work is being conducted on the selection of the process for t11e upgraded facility. Possibilities include switching to an activated -sludge process, addition of a redundant clarifier and addition of new sand filters. A finalized design, will not be ready for sometime, but upon completion, will be submitted to the department for review- SPDES PERMIT COMPLIANCE The following parameters are permitted and were analyzed for on a monthly basis: Parameter Flow BOD, 5 -day pH Suspended Solids, Total Settleable Solids Zinc Iron Lead Silver Copper Ammonia Chlorine Residual - Coliform, Total General Coliform, Fecal General Limit 1.8 MGD, 30 day avg. 10 mg/1, 30 day avg/20 mg/1 max. 5.8 9_0 SU 5 mg/1, 30 day avg/1'0 mg/l max. 0.1 mg/1 max. 0.3 mg/l max. 0.6 mg/1 max. 0.067 mg/1 max. 0.05mg/1 max. 0.4 mg/1 max. 2.0 mg/1 max. 0.05 mg/1 max. 10,000 mg/1 max., 2,000 mg/1 max. K-3 Temperature Radioactivity Radium 226, Total Strontium 90, Total 90° F. max. 1,000 PCI/L max. 3.0 PCI/L max. 10.0 PCI/L max. A review of the Discharge Monitoring Reports (DMRs) prepared arid submitted by the firm for the period extending from January, 1990 through February, 1992, indicated that the maximum average - monthly flow recorded at the facility was 1.1 million gallons per day while the average flow for the en -tire period was approximately 0.792 million gallons per day. Only a few permit violations were recorded during that period; Parameter Number of Violations High Concentration Total Suspended Solids, 2 9.9 mg/1 Avg. Concentration Total Suspended Solids, 5 30.0 mg/1 Max. Concentration Total Settleable Solids, 1 8.8 mg/l Max. Concentration However, all of the violations occurred in the first half of 1990. and it appears that the problem has been corrected.. During the same period, no departmental sampling violations were recorded at the'facility; as such, the plant must be considered well operated. TOXIC OR -HAZARDOUS MATERIAL STORAGE Toxic and hazardous material are stored at the Brookhaven National Laboratory under facility identification number 2-0026. At ,the present time, there is a total of 225 storage facilities (tanks). Of that number 138 are out of compliance with Article 12 ,of the Suffolk County Sanitary Code. The facilities include the following: Outdoor tanks Indoor tanks 64 74 However, Brookhaven National Laboratory has".not had time Uo respond to the department's request as to the status of any indoor tanks. A .complete listing of the tanks is contained within Appendix A. CONCLUSION Wastewater treatment facilities at Brookhaven National Laboratory are .in satisfactory condition and are well operated. Flans are in progress to upgrade the present facilities to help -ensure Lh e continued protection of the Peconic River. Ongoinig K-4 t investigations, such as the Long Island Sound Study and the Brow►i Tide Comprehensive Assessment and Management Yrograiii, iiiay recommend that nutrient (nitrogen) discharge be limited. if implemented, the recommendation would change the scope of the presently proposed upgrading to include denitrification. Over half of the storage facilities are currently not in compliance with Article 12 of the Suffolk County Sanitary Code according to the department's records; however, when all Lhe information that has been requested from the lab is received and reviewed, this number may substantially decrease.

K-13 BROOKHAVEN 14ATIONAL LABORATORY Office of Environmental Restoration SITE OVERVIEW B May 1991 K-14 1.0 INTRODUCTION Brookhaven National Laboratory (BNL), located on 5265 acres in Upton, New York, is owned by the United States Department of Energy (USDOE) and operated by Associated Universities, Inc. (AUI). The site, formerly known as Camp Upton, was used by the U.S. Army during World Wars I and II and as a Civilian'Conservation Corps (CCC) Camp between wars. In 1947, BNL was established as a multidiscipline, scientific research center, with emphasis on programs that require large-scale research tools, 'such as nuclear reactors, particle accelerators, and physical, biomedical, and environmental laboratories. Radioactive substances and'a number of substances defined as hazardous under Federal and State regulations have been and are being acquired, used, stored, and disposed of at BNL as a result of these research activities. Consequently, certain hazardous and radioactive substances, pollutants, and constituents have been released into the air, soil, surface sediment/water, and groundwater. Currently, no environmental problems at BNL present an immediate threat to human health. Brookhaven National Laboratory is located in one of the most environmentally sensitive areas areas in the country, principally because it is situated on a sole source aquifer which provides potable water for Long Island. On November 21, 1989, BNL was included as a Superfund Site on the National Priorities List (NPL). BNL plans to remediate areas of known contamination and pursue its program of continued surveillance in order to identify, mitigate, and eliminate other areas of potential contamination. BNL's current environmental program is aimed at all pathways and targets of potential contamination, with an emphasis on groundwater protection and remediation. BNL's strategy for providing environmental protection involves three distinct activities. The first activity is corrective action which will upgrade existing facilities into compliance with current and future environmental regulations. The second activity is the environmental restoration of the BNL site, in order to ensure that the threat to human health and welfare and to the environment are reduced to acceptable levels. The third activity is waste management, which will assure environmentally sound waste management operations and minimize the amount of waste generated by SNL. 1.1 AREAS OF CONCERN As a result of accidental spills and past operational practices in the handling and disposal of radioactive and hazardous, contaminated sites have been identified at BNL. The resultant contaminated locations have been grouped under a single heading of Areas of Concern (AOC)e, based on the Interagency Agreement (IAG) under'the Comprehensive Environmental Response, Compensation, and Liabiliy Act of 1980 (CERCLA), Section 120 between USDOE, United States Environmental Protection Agency (USEPA) Region II, and the New York State Department of Environmental Conservation (NYSDEC) concerning BNL. The Interagency Agreement, which will be signed in 1991, intends to integrate DOE's response obigations under CERCLA, Resource Conservation and Recovery Act (RCRA), National Environmental Policy Act (NEPA), and New York State hazardous waste regulations. The AOCs presently number twenty-four and could possibly increase as a result of further sitewide investigations (e.g. Historical Site Review -Scheduled for FY91). The ADCs are defined as Solid Waste Management Units (SWMUs) and non-SWMU locations where releases of a hazardous substance, pollutant or contaminant K-15 (including radionuclides) under CERCLA in the environment have occurred or may have occurred. The Site Baseline Report (Draft), generated under the IAG, identifies the current twenty-four AOCs and provides the operational and environmental information needed to establish a baseline understanding of each AOC ( see Figures 1-1 through 1-5). The Site Baseline Report (Draft) was compiled through an intensive search of existing !records and documents, interviews with BNL employees (current and retired), and site walkovers. A summary of this information is provided in the following subsections and in Table 1-1. Information on past practices and estimates of the quantities and types of contaminants for several AOCS are very limited. However, significant amounts of historical monitoring data exists as a result of BNLLIs environmental monitoring program which has encompasses the more significant AOCs for decades. Recently, the twenty-four AOCs have been categorized, grouped, and prioritized in the Response Strategy Document (Draft), generated under the IAG. The Response Strategy Document (Draft) categorized the AOCs/SubAOCs according to several decision points based on the existing knowledge of each AOC/SubAOC. As a result, the twenty-four AOCs were categorized into Preliminary Assessment/Site Investigation (PA/SI) AOCs, Candidate Completed AOC, Remedial Action AOCs, and Removal Action AOCs. The PA/SI AOCs require a preliminary site investigation in order to categorize and group them into either Operable Units, Removal Action AOCs, or Candidate No Action AOCs. ADCs that require further characterization and remediation were categorized as Remedial Action AOCs. The Remedial Action ADCs were later grouped into Operable Units. Non -time critical removal actions currently being addressed under the IAG were categorized as Removal Action AOCs. Table 1-2 indicates the categorization of AOCs/SubAOCs at BNL. The Remedial Action AOCs .were grouped into Operable Units, by utilizing a selective criteria based on similarities and interrelationships of ADCs/SubAOCs (a. g. relative proximity, similar site problems, etc..). The. Operable Units will each undergo the Remedial Investigation/Feasibility .Study -Environmental Assessment (RI/FS-EA) process (see Figure 1-6). The grouping of AOCs into OUs provides a streamline approach to the RI/FS-EA program at BNL. The streamlined approach provides the following benefits: a reduction in the amount of independent investigations, a reduction in the number of reports generated, and an overall reduction in the amount of time spent by necessary BNL/DOE, regulatory, and public reviews. Once categorized, the Operable Units and Removal Action AOCs were then prioritized by the Response Strategy Document (Draft) using priority criteria, in order to indicate the best order of response by BNL (see Table 1-2'). The priority criteria considered the following factors: health and safety, regulatory constraints, institutional constraints, a preliminary risk assessment, public concern, funding, and technical interrelationships. The following subsections provide summarized information concerning each AOC that was compiled in the Site Baseline Report (Draft) and factored into the Response Strategy Document (Draft) prepared at BNL from 1990 to 1991.

Activities are located within a fenced area of aproximately 12 acres in the southeastern portion of the site. One Butler=type metal building (Building 448) is used for the following: interim storage of small, lightly activated materials for reuse; interim storage of mixed_ scintillation wastes, and bulk nonradioactive equipment, such as cement mixer, plywood, and recovery drums. Another Butler -type metal building (Building 444) -is used for storing and sorting nonradioactive hazardous chemical wastes. One section in the sorting area of this building is used as a charging area for the pathological waste incinerator. A larger, heated, Butler -type building (Building 446) is used for sorting radioactive wastes. The compactor for dry, compactible waste is also located in Building 446. Use of the compactor allows a volume reduction factor of 4-5 for this waste stream. The Works Area Building (Building 445) is a more permanent type building with heat, sanitary, and shower facilities, locker and change rooms, counting room, -shop, lunch, and workrooms. The outdoor paved works area is used for preparing radioactive waste packages. Six government surplus railroad box cars provide bulk storage of new drums, cement, and vermiculite. A fiberglass paneled shed with a metal roof and concrete pad and sumps (Building 483) is used for storage of drummed nonradioactive hazardous materials. These failities are more extensively described in documentation submitted under the RCRA hazardous waste permitting process. The underground storage area is used for interim storage of large, bulky, highly radioactive items that are received from Brookhaven experimental areas. Those which generate- radiation levels sufficiently high to prohibit immediate safe handling and transport are stored in concrete lined trenches. The inside dimensions of these trenches are 22 feet long, 2 feet wide, and 4 feet deep. They are covered to prevent leaching due to rain. In addition, there are a number of vertical (9 feet deep) and slanted (12 feet long) storage vaults which are also employed for interim storage. The detonation area (SubAOC 1A) is surrounded on three sides by an earthen berm approximately 8 feet high. When chemical or gaseous waste were .too unstable due to age or the condition of the container, they were destroyed through detonation or opened with rifle fire. This method was -last employed in 1985 and operation has since ceased. The field storage area (SubAOC 1C and SubAOC 1D) is used for interim'storage of slightly activated material; such as -iron magnets, copper windings, and stainless steel components from the dismantled Cosmotron. As permitted by activity levels, some of this material has been released -for reuse by laboratory operations. A major campaign was conducted in 1988 to package and ship a substantial fraction of this material for disposal off=site. There are no active facilities for radioactive waste disposal at Brookhaven. At the present time, all radioactive waste is shipped to Westinghouse/Hanford (DOE) for burial. Spills and releases in the past have resulted in contamination of soil and paved areas with radioactive and hazardous materials. The following SubAOCs represent K-35- these types of areas: SubAOC 1E -Drum Rinsing Area, SubAOC 1F -Radioactive Material (Fission Product) Injection Site, SubAOC 1G -Miscellaneous Spill Sites, SubAOC 1H -oil -Water Separator, and SubAOC 11 -Neutralization Tank and Area. A network of groundwater monitoring wells is in place around the area. These wells indicate the presence of chlorinated organics, tritium, and strontium. In 1985, based on results of the environmental monitoring program and the results of an independent study (H2M, at al., 1985), the Laboratory intiated an aquifer restoration program to remediate a plume of volatile organics migrating from this area (SubAOC 1B -Spray Aeration Site). The remediation consisted of five recovery wells with spray discharge nozzles designed .to intercept and remove the volatile organic compounds from the groundwater. Since installation, the system has operated during nonfreezing weather with an estimate efficiency of approximately 99%. The average concentration of volatile organic compounds in the plume has dropped from over 2,000 parts per billion (,ppb) to below 100 ppb. The current drinking water standard is 5 ppb for volatile organic compounds. In 1990, the NYSDEC requested the termination of the spray aeration program, until further review. The HWMA will be remediated under the IAG as part of Operable Unit I (see Table 1-2). Operable Unit I will be remediated under one RI/FS-EA program. 1.1.2 AOC 2- Former Landfill Area The Former Landfill Area encompasses approximately twelve acres; the areal extent was estimated by examination al- historical maps and aerial photographs. It includes the former landfill (SubAOC 2A), chemical/animal pits (SubAOC 2B), the glass holes (SubAOC 2C), a interim dump (SubAOC 2D), a slit trench (SubAOC 2E), and the ash pit (SubAOC 2F). These are located in the same general area, and, for purposes of site assessment and examination, are classified as one site. The former landfill was initially used as a waste disposal site by the Army. The entire landfill area covers an estimated eight acres. The area used by the laboratory for general waste disposal for a twenty year operating period (1947- 1966) is approximately three acres in size. Records of the quantities of radioactive waste deposited in this area were maintained. However, detailed records of nonradioactive waste that were placed in this disposal site do not exist. The amount of the material is composed of construction and demolition debris. In order to arrive at a reasonable estimate of the quantity and types of refuse disposed of at this site, the results of a survey- (Gibbs and Hill, 1966) of the landfill operations were examined. The information indicated that, on the average, approximately three tons of refuse were deposited on the landfill each working day. This survey also indicated that approximately 50%, of the material landfilled during the observed period was burnable material. This rather large amount of burnable refuse was landfilled because of the limited capacity of the incinerator operating at that time. Information supplied by BNL employees indicates that open dump burning was frequently used during the former landfill operation, resulting in volume reduction over the years. Various types and quantities of nonradioactive chemicals were disposed of in the landfill until approximately 1960, when BNL restricted the disposal of such K-36 items, as well as animal carcasses, to open pits or chemical holes. Based on discussions with BNL personnel, it can be assumed that. the landfill continued to receive some chemical wastes until its use was discontinued in 1966. Only limited records exist of chemicals disposed in this manner. It is recognized that both deliberate open burning for purpose of volume reduction and the occurrence of spontaneous fires may have served to -reduce the quantities of chemicals contaminating the area. Since 1966, when use of the dump was discontinued and a new landfill was established, surplus chemicals have been processed at the HWHA and shipped off-site to a commercial disposal agency. Stringent administrative controls from 1947-1966 were not considered.necessary for nonradioactive material. During the early 1960x, attempts were made to restrict the disposal of chemicals and animal carcasses to open pits, which were used until 1966. Within this time period, these chemical/animal holes were used for general disposal of laboratory waste chemicals and animal carcasses, most of which contained low-level carbon-14 radioactivity. BNL employees estimate that acid and base disposal comprised the greatest volume of chemicals. It was reported that organic compounds were often burned at the former landfill. Records do not offer an accurate account of types or quantities of these waste materials disposed at the site. Estimates -of the number of chemical and glass holes ranged from 10 to 25. The holes were roughly 10 to 12 feet in diameter, and estimates of depth ranged from 10 to 20 feet. Twenty-eight suspected chemical or animal holes were identified by historical .photographs and topographical characteristics such as land settling, lack of vegetation, earthen mounds from previous excavation, and remnants of snow fencing. Pits in,the glass hole area were used for the disposal of rinsed laboratory glassware after the use of the chemical holes was discontinued in 1966. BNL personnel indicated that small quantities of chemicals were occasionally disposed of in these pits. The use of this means of disposal was discontinued in 1981. A small dump was used for a short period of time as a temporary landfill during 1966 while preparations were underway for the operation of the current landfill. This site also may have received some quantities of chemical waste. Initial calculations indicate that the area is approximately 3/4 of an acre in size. A alit trench also has been identified. The trench was approximately 10 to 15 feet deep, 15 feet wide, and 230 feet long. This trench was used for disposal of construction debris and is not expected to have received chemical waste. The ash pit was identified from aerial photographs. It is suspected of being used during the 1950s and 1960s until the incinerator was removed from service. Borings and field investigations indicate that ash and incinerator slag ae present at depths up to approximately four feet within an area of about one acre. Current monitoring data indicates that this area has not impacted groundwater quality. A network of groundwater monitoring wells is in place, and surveillance of the former landfill area is part of the environmental monitoring program. Data from these wells are published -in the Annual Site Environmental Report. Values for pH and the concentrations of gross alpha, gross beta, strontium -90, iron, manganese, and various organic compounds have been found in excess of applicable regulatory standards. K-37 The Former Landfill Area will be remediated under the IAG as part of Operable Unit I (see Table 1-2). Operable Unit I will be remediated under one RI/FS-EA program. 1.1.3 AOC 3- Current Landfill The Current Landfill was put into operation in January 1967, after the former landfill (see Subsection 1.1.2) was filled and covered. small amounts of radioactivity, in the form of laboratory waste such as paper towels, animal carcasses containg short-lived radionuclides, sewage sludge, and mouse litter containing tritium, have been disposed of in the landfill. However, this practice was discontinued in September 1978. Putrescible and nonputreecible trash and gross building materials were dumped at the current landfill since its beginning. However, since February 1981, putrescible garbage has been taken offsite to the Brookhaven Town Landfill. The landfill was closed on December 18, 1990 at the request of the NYSDEC, because no liner exists as required by the Long Island Landfill Law. All trash and materials are collected in packmasters and load luggers. Trucks from onsite construction contractors also deposit materials at the landfill. It is estimated that each working day, six to eight tons of nonputrescible trash and gross building materials were put on the landfill. The landfill trash has always been compacted. Since 1974, it has been compacted daily to the smallest practicable volume and covered with six inches or more of fill material. Asbestos was disposed of separately in trenches in an assigned area at the southwest corner of the site. The current landfill area is surrounded with chain link fence, and groundwater monitoring wells are located in the immediate vicinity for measurement and surveillance of any impact of the landfill on the groundwater quality. BNL's administrative controls exercised through the BNL Safety Manual provide mechanisms to eliminate the potential for disposal of radioactive or hazardous chemicals in the current landfill. The landfill radiation monitor provides a second measure of protection in preventing low-level contaminated materials from reaching the landfill. The environmental groundwater monitoring surveillance program provides an additional line of defense if inadvertent disposal of toxic or radioactive material were to occur. Presently, groundwater data indicates that radionuclide concentrations are presently below groundwater standards and are diminishing, while organic compound concentrations are low and sporadic. The only widespread contaminants found are iron and magnanese, which exceed secondary drinking water standards. The Current Landfill will be remediated under the IAG as part of Operable Unit I (see Table 1-2). Operable Unit I will be remediated under one RI/FS-EA program. 1.1.4 AOC 4- Sewage Treatment Plant Area The Sewage Treatment Plant (STP) is made up of a clarifier for primary treatment and a sand filtration system for secondary treatment prior to discharge into an intermittent stream which forms the headwaters of the Peconic River. The Sewage Treatment Plant has a current average flow of 700,000 to 800,000 gallons per day. K-38 Previously, an Inhoff tank (SubAOC 4C) was used for separation of solids, but was abandoned in 1967. Eight tile lined, sand filter beds (SubAOC 43) at the STP are used for periodic passive dewatering of sludge from the clarifier. Two polyethylene -lined ponds are used for overflow and as holdup ponds (SubAOC 4D) when the STP influent exceeds acceptable limits for conventional treatment. Chlorination of the effluent was terminated during May 1988 in response to the requirements of the New York State Pollution Discharge Elimination System (SPDES) program. The liquid effluent is monitored for radioactivity and other indices of water quality at points into and out of the settling tank and before it enters the Peconic River, to verify that concentrations are well below the maximum permissible levels and in accordance with SPDES permit requirements. The sludge from the anaerobic digester is also monitored and pumped to drying beds (SubAOC 4A) before being stored in connexes for shipment, if radioactivity exists. The sludge is treated as low-level radioactive waste and processed through HWMA for off-site disposal. In 1978, an emergency holdup facility capable of retaining 4 million gallons of effluent was installed adjacent to the sand filter beds to prevent inadvertent discharge of contaminants. This capacity was increased to 8 million gallons in 1989. This system is activated by an alarm network in the Sewage Treatment plant and triggered by such parameters as oil, conductivity, pH, and radioactivity. If necessary, the transfer from the normal made to the emergency holdup mode can be performed manually. The decision to reroute to the normal mode is made by the Safety and Environmental Protection Division after evaluation of analytical results by the Environmental Protection Section. In addition to sanitary sewage, various radioactive and hazardous wastes have been inadvertently discharged into the sanitary system. As a result, several areas of the STP which have been contaminated are designated as SubAOCs. These SubAOCs are as follows: SubAOC 4A -Sludge Drying Beds, SubAOC 48 -Sand Filters, SubAOC 4C-Inhoff Tank Sludge, and SubAOC 4D -Holdup Panda. Another area not related to the operations at the STP, the Satellite Disposal Area (SubAOC 4E), was included in this AOC due to its close proximity to the STP. Around 1960, the Satellite Disposal Area, located east of the STP, was used for the disposal of unknown chemicals (1 to 5 pounds) in four or five, hand -excavated holes. In addition, during the mid -1960'x, a trench was dug in this area for the disposal of twelve leaking, bromine trifluoride, cylinders. In 1987 these cylinders were exhumed, found to be empty, and disposed of in the Current Landfill (see Subsection 1.1.3). The groundwater in the STP area is monitored by a series of monitoring wells located around the STP and along the Peconic River. Concentrations of Strontium - 90 above drinking water standards and elevated levels of tritium, and gross beta have been found in some of these wells. The observed tritium -and gross beta levels are attributable to losses from the tile collection field underlying the sand filter beds and from the recharge to the groundwater from the Peconic River. Various high values of iron, manganese, lead, and zinc have been measured in some of the STP wells. Organic compounds have been measured*at low concentrations in three wells on limited occasions. Most of AOC 4 -Sewage Treatment Plant will be remediated under the IAG, as part K-39 of Operable Unit V (see Table 1-2). The two remaining SubAOCs at the STP, SubAOC 4C-STP's Inhoff Tank Sludge and SubAOC 4D-STP's Holdup Ponds, will undergo a Preliminary Assessment/Site Investigation inorder to determine further categorization according to the Draft -Response Strategy Document. 1.1.5 AOC 5- Central Steam Facility The Central Steam Facility (CSF, Building 610) is located along the eastern perimeter of the developed portion of the laboratory. The CSF -supplies steam for heating and cooling to all major facilities through the underground steam distribution and condensate grid. From 1976 through 1987, the CSF utilized alternate liquid fuel in the four high efficiency boiler units for the purpose of energy recovery. The existing steam -generated system's design capacity is 410,000 lb/hr. The fuel oil storage and transfer system is an installation having a total capacity of approximately 2 million gallons. Fifteen tanks are used to receive and store the various flammable liquids used as fuel. This fuel is currently comprised of heavy residual fuel oil and blended fuels. In 1977, an empty 5,000 -gallon underground tank was forced upward by water whichi had accumulated in the surrounding enclosure following heavy rainfall, causing a connecting pipeline to rupture. It was estimated that approximately 23,000 gallons of a mixture of 60% No. 6 fuel oil and 40% wastes solvents was discharged to the surface. The spill was contained with sand and approximately 15% of the free product was recovered. Soil removal was conducted, and total recovery of the spill has been estimated to be up to 80%. Subsequent cleanup procedures involved tilling and fertilizing of the soil during the following spring in order to enhance bacterial degradation of remaining soil contamination. This approach was approved by the US EPA and NYSDEC. In 1985, soil contamination was found in the area when soil borings were taken as part of a study to expand the CSF. Later contamination was encountered during the installation of monitoring wells that were required by the NYSDEC Major Petroleum Storage Facility Permit regulation. SNL contracted the services of an environmental and engineering consultant to investigate the magnitude and extent of groundwater and soil contamination (ITC, 1988). A soil gas survey was conducted to allow a preliminary assessment of the areal extent of soil contamination. Areas near the reported spill and immediately to the south and west were identified for further study. Soil samples from a range of depths were collected for laboratory analysis from five soil borings and one monitoring well boring. Other soil samples were screened in the field for further information regarding the vertical distribution of contamination. Five monitoring wells were installed to determine subsurface geologic conditions, define the local hydrogeological regime, and provide ground water sampling points. To obtain the geologic information necessary for a site assessment, soils from above and below the watertable were characterized in the field during drilling, and information regarding the hydraulic conductivity of the aquifer deposits was obtained using field tests. Chemical analyses of the six soil sampled did not find detectable concentrations of volatile or base/neutral extractable organic compounds. Total petroleum hydrocarbon compounds were detected in three samples, at concentrations ranging from 33 to 71 parts per million (ppm). K-40 Bacterial population measurements were performed on three soil samples to assess the potential for in situ biodegradation of contaminants. Low to average populations of total and hydrocarbon -degrading bacteria were found. A nutrient stimulation study of one, of the samples indicated that these populations are limited by the availability of microbial nutrients and oxygen, and can ne stimulated to increase substantially. Groundwater was encountered at a depth of approximately 35 feet and presently flows toward the south across the spill area. The groundwater sample from monitoring well IT -1 within the spill area was found to contain a_range of volatile organic compounds, with a total concentration of 6.7 ppm and largely composed of aromatic hydrocarbons. Total petroleum hydrocarbon compounds in this sample was 6.8 ppm. The extent of the groundwater contamination downgradient is estimated to be 500 feet, and the soil contamination extends over approximately one acre. Hence, groundwater in close proximity to this spill area contains concentrations of organics that exceed state_ drinking water standards (5 ppb) and will require remediation. In addition, radionuclides and metals, have been detected in the CSF wells. Minor concentrations of sodium -22, strontium -90, and cobalt -60 were found. Iron and manganese have been measured in concentrations exceeding groundwater standards in several wells. In 1989, mercury was found in two wells which exceeded state drinking water standards. In addition to the spill incident (SubAOC SA-Oil/Solvent Spill), the Central Steam Facility contains other subAOCs, as follows: SubAOC 5B -Former Leaching Pit, SubAOC 5C -Underground Piping, and SubAOC 5D -CSF Fuel Unloading Areas. These subAOCs are the result of the handling, transferal, or storage of fuel at the CSF. In 1990, the leaching pit, which contained a thick black tarry material, was excavated and 300 cubic yards of contaminated soil was removed. Soil samples were taken and the NYSDEC's Oil Spill Group confirmed that the leaching pit was sufficiently remediated based on visual observations. Clean sand and soil from another part of the lab was placed in the hole as fill. However, the impact on the groundwater has not been determined thus far. The underground piping and fuel unloading areas are suspected sources of contamination. There Is no history of leakage in the underground piping reported to date, however, these areas cannot be visibly inspected. The fuel unloading areas have several spills documented from 1987 to the present. The spills range in volume from two to six gallons and for the most part were No.6 fuel oil, with one incident of No.2 fuel oil, and one incident of gasoline spillage. All of the spills were remediated using absorbents.or .recovered into storage tanks. However, the impact on the groundwater has also not been determined. The Central Steam Facility AOC will be remediated under the IAG, as part of Operable Unit IV (see Table 1-2). Operable Unit IV will be remediated under one RI/FS-EA program. A draft work plan is currently being reviewed under this RI/FS-EA. K-41 OC 6- Rec_lamaion Facility Building 650 S As a result of contractor error, inadvertent release of slightly radioactive contaminated drainage water from the Reclamation Facility (Building 650) occurred during the 1960s. Rain falling on the asphalt when not in use was intended to be kept from the active waste holdup tank and routed to the sanitary sewage system. Instead, the drainage was piped to a sump rather than the sanitary system. Although, this condition existed for approximately ten years before discovery in 1969, it is estimated that no more than 2 millicuries (mCi) of alpha, 55 mCi of cesium -137, 1 mCi of strontium -90, and 5 curies of tritium were discharged to the ground. Between 1971 and 1973 several groundwater monitoring wells were installed in the Bldg. 650 sump area. Elevated levels of tritium, gross beta, strontium -90, chlorides, phosphorous, and temperature found in the groundwater are probably induced from the effects of the AGS recharge basin nearby and not associated with releases from Bldg. 650. However, together with the lack of current data (past 5 years) and the uncertainty of existing data, the full nature and extent of contamination is currently unknown. The Reclamation Facility Bldg. 650 Sump Area AOC will be remediated under the IAG, as part of Operable Unit IV (see Table 1-2). Operable Unit IV will be remediated under one RI/FS-EA program. 1.1.7 AOC 7- Paint Shop Building 244 Building 244 has been and is currently being used by Paint Shop Operations. As a result of past brush cleaning practices, paint -stained soils were present at the rear of the paint shop. The method of brush cleaning outdoors was discontinued. Present Paint Shop methods for brush cleaning calls for the collection of all wastes in containers and provides for the proper off-site disposal by Hazardous Waste Management. Soil sampling and analysis detected organic compounds at a maximum concentration of 7 ppm in the paint stained soils: During remedial activities in 1988, the contaminated soils were excavated to non-detectable levels and removed to the Hazardous Waste Management Facility in 55 -gallon drums for off-site disposal. In 1989, two groundwater monitoring wells were intalled in the paint shop area. Organic compounds were found in these wells. However, the organic compounds found in these wells may reflect deeper contamination- from a unidentified upgradient source and not be related to paint shop activities, 'since these wells are screened well below the water table. AOC 7 -Paint Shop was determined to be a Candidate Completed AOC, based on the Draft -Response Strategy Document's findings. The AOC was placed in this category because response actions. were adequately completed before the effective date of the IAG. No further action will be taken at this AOC. 1.1.8 AOC 8- Upland Recharge Area/Meadow Marsh The Upland Recharge Experiment, conducted as a cooperative effort with the Town of Brookhaven, was initiated in mid -1973 and terminated in 1978. The liquid effluent utilized for this experiment was a composite of cesspool pumping from off-site residential areas and BNL sewage. Primary untreated effluent and K-42 secondary treated laboratory effluent mixed with raw cesspool pumping effluents were applied to a series of plots in the southestern portion of the site in order to conduct various experiments. Groundwater monitoring wells were installed in the upland' recharge 'area. No organic compounds have been detected in the groundwater at the AOC. However in 1989, copper, iron, and manganese concentrations were evident in excess of regulatory drinking water standards, however, these were lower than background levels. Presently, tritium is the primary contaminant at the AOC. However; mixing and decay [half-life (12.3 years)] over the period time since operations have ceased at the AOC, should have substantially reduced concentrations. AOC 8 -Upland Recharge Area/Meadow Marsh will be remediated under the IAG, as part of Operable Unit VI. Operable Unit VI consists solely of this AOC which will be remediated under one RI/FS-EA program at BNL. 1.1.9 AOC 9- Brookhaven Graphite Research Reactor The Brookhaven Graphite Research Reactor (BGRR) was retired from service after 18 years of continuous operations as one of the principal research reactors in the United States. It was constructed in the late 1940s and began operations in August 1950. It was the first reactor built in this country solely to provide neutrons for research, and its size and special design allowed it to support a large number of research programs simultaneously. The BGRR was a graphite moderated and reflected, uranium -fueled, air-cooled reactor. It consisted of a graphite cube penetrated in the north -south direction by an array of parallel horizontal channels which contained the uranium fuel elements. Air was drawn through the fuel channels, and after filtering and cooling, was discharged through the reactor stack. In June 1968, the BGRR'was shut down because the Brookhaven High Flux Beam Reactor had proved to be a superior and- more economical research tool. A program was then initiated to reduce to a minimum the radioactive material within the shield and to assure that any residual contamination and radioactive materials could not escape from the shield. This program consisted of removing all the fuel elements from the graphite core area, removing from the reactor all experimental apparatus that could not safely be left for an extended period, and closing and sealing all penetrations through the biological shield. One opening on the top of the reactor now vents the shielded area through an absolute filter. Monitoring of the air coming through the filter indicates that no airborne radioactivity is escaping from the reactor through this vent. All fuel elements were removed through the fuel storage canal and subsequently shipped off-site to a fuel reprocessing plant, and the canal was drained and cleaned. These steps were, completed in June 1972, and since that time, no contamination problems have arisen. The BGRR facility can be maintained in this condition for an indefinite period. The office and laboratory space in the reactor building is now being used for other projects. Part of the original complex is a visitor center and museum. Several potential sources of contamination have been identified at the BGRR and three subAOCs have been designated, as follows: SubAOC 9A -Canal, SubAOC 9B - K -43 Underground Ductworks, and SubAOC 9C -Spill Sites. The canal and underground ductworks are suspected of leaking an unknown quantity of radioactive water into the surrounding subsurface, during the facility's operation. The surficial spill sites located around the reactor building have been remediated in the past, but may still contain residual radioactive contamination in certain areas. Unfortunately, only radiological survey data is available concerning these areas. No soil or groundwater monitoring has been performed in these subAOC areas to date. Most of AOC 9 -Brookhaven Graphite Reactor will be remediated under the IAG as part of Operable Unit II (see Table 1-2). The remaining subAOC, SubAOC 9B - Underground Ductwork, is designated as a non -time critical Removal Action AOC and will be remediated separately. 1.1.10 AOC 10- Waste Concentration Facility Aqueous radioactive wastes are processed through the Waste Concentration Facility (WCF), Building 811. Within the WCF's 5,000 gallon blending tanks, final pH is adjusted prior to being fed into the evaporator. BNL's Vapor Compression Evaporator unit, which has been in operation since 1953, provides a liquid volume reduction of approximately 100:1. The distillate is monitored as it is collected in a tank. It is then transported to a holding pond near the Sewage Treatment Plant for interim storage prior to release. The slurry, which is the residue of the evaporation process, contains the solids as well as most of the radioactivity. Tritium is distributed throughout the distillate and slurry. The slurry is subsequently processed at the WCF and packaged for off-site disposal. This processing consists of the addition of the liquid waste to a 3:1 mixture of vermiculite and cement inside a shipping container. There are three 100,000 gallon, outdoor, above -ground waste storage tanks (SubAOC 10A) at the WCF which received wastes from the BGRR and associated laboratories. These tanks were operated from 1949 until 1987, when the sludge present in the tanks was removed, solidified in cement, and packaged for disposal off-site (Chem Nuclear Services, 1986). These tanks are empty and scheduled for decontamination/decommissioning. Several D -waste liquid pipelines were installed to carry approximately 80,000 gallons of radioactive liquid waste to the WCF from the BGRR, the Hot Laboratory - Building 0801, and from the High Flux Beam Reactor. It is not known if these lines leak. The outer conduit which is 28 years old, has deteriorated to a point where if the inner piping leaks, potentially nondetectable waste spills may occur. The tunnel portion of the D -waste system is approximately 38 years old. Groundwater monitoring wells in the WCF area have reported organic compounds, iron, manganese, copper, and zinc above regulatory drinking water standards. Radiological results for the groundwater from the wells at the WCF, indicates the presence of sodium -23 in most wells and slightly elevated strontium -90 concentrations in two wells, both were below regulatory standards. However, these wells are screened substantially below the water table and may possibly reflect deeper contamination from a more distant unidentified source. Half of AOC 10 -Waste Concentration Facility will be remediated under the IAG as part of Operable Unit II (see Table 1-2). The remaining subAOC, SubAOC 1OA-D- Tanks, is designated as a non -time critical Removal Action AOC and will be K-44 remediated separately. 1.1.11 AOC 11- Buildinc_830 Pipe Leak In 1986, inspection of liquid radioactive waste levels in the Building 830's underground holding tanks and the waste inventory records revealed that there was a 825 to 900 gallon discrepancy between July, 1984 to August, 1986. Leak tests revealed that the source of the loss was the transfer line between the building and the underground holding tanks. The contaminated soil as a result of the leak was removed until radiological measurements indicated background conditions. The -pipes and tanks were subsequently abandoned and the excavated area was backfilled and paved. The tanks and associated piping will be removed under the Underground Storage Tank Removal Action AOC (see 1.2.1.12). In 1989, three groundwater monitoring wells were installed to monitor the AOC. Groundwater data from these wells, in 1989, indicated tritium, chloroform, and phenol concentrations evident at the AOC, all below state drinking water standards. AOC 11 -Building 830 Pipe Leak will be further remediated under the IAG, as part of Operable Unit III (see Table 1-2). Operable Unit III will be remediated under one RI/FS-EA program. 1.1.12 AOC 12- Underground Storage Tanks The laboratory uses undergound, above -ground, and indoor storage tanks for the storage of fuel, radioactive liquid waste, and other liquid materials. AOC 12 concerns only the fourteen underground storage tanks which contain or had contained radioactive liquid waste on-site. The other nonradioacive waste storage tanks are now being removed, replaced, or upgraded to conform to Suffolk County Sanitary Codes and EPA regulations under the 4 -phase program initiated by BNL. In 1990, the radioactive waste storage tank sludges were sampled and a conceptual treatment plan was developed. The results of the sampling and analysis revealed concentrations of radionuclides, organic compounds, and metals in most of the tank sludges. Radiological results in one tank were very high. Due to the complexity of handling and disposal of such wastes and the respective tanks under the IAG, a Engineering Evaluation/Cost Analysis (EE/CA) will have to be developed. The EE/CA may include plans for treatability testing of the waste and the removal, decontamination, and disposal of the tanks and their contents. Presently, AOC 12 -Underground Storage Tanks is designated as a non -time critical Removal Action AOC and will be remediated under the IAG. 1.1.13 AOC 13- Cesspools The New York State Department of Health has determined that industrial cesspools are no longer acceptable means of waste disposal on Long Island. As a result, BNL have identified, sampled, excavated, backfilled, or abandoned numerous cesspools. Cesspools have been used since at least the 1950's at BNL for the disposal of liquid waste from many buildings where topography and building locations did not facilitate gravity feed for sewage hookups. These subsurface disposal systems were not subject to regulatory permitting with respect to the types of wastes in them until fairly recently. Sanitary waste was mainly sent to the cesspools, however, hazardous and low -radioactive waste may have been disposd of in the cesspools via wash sinks and floor drains. In 1989, DOE Survey sampling of various cesspools indicated varying concentrations (some elevated) of metals, volatile/semi-volatile organic compounds, and radionuclides. In 1990, K-45 all cesspools, except for two newly found, have been removed from service and the applicable buildings were connected to the on-site sewer system. BNL is continuing to identify, sample, and remove cesspools from service. Presently, AOC 13 -Cesspools is designated as a non -time critical Removal Action AOC and will be remediated under the IAG. Currently, a draft comprehensive sampling and analysis plan has been submitted to EPA for review. 3 1 14 AOC 14- Bubble Chamber Spill Areas An area near the Bubble Chamber Area at BNL has been used for the temporary storage of hazardous materials in drums and above-ground/underground storage tanks. The only documented spill in the area consisted of a release of scintillation oil during the excavation of a 275 -gallon underground storage tank, in 1989. Scintillation fluid is composed primarily of toluene, a volatile organic compound. The approximate 20 gallons of oil that was spilled was pumped into a drum and the subsequently stained soil was removed and placed in drums. Soil was removed until only soil which had been determined to be clean remained. It was noted, that much of the soil contamination found was most likely a result of past events. In 1989, groundwater monitoring wells located at the site demonstrated concentrations of radionuclides, organic compounds, and metals. The organic compound concentrations at the time exceeded drinking water standards. AOC 14 -Bubble Chamber Spill Area will be further remediated under the IAG, as part of Operable Unit III (see Table 1-2). Operable Unit III will be remediated under one RI/FS-EA program at BNL. 1.1.15 AOC 15- Supply/Potable Wells The BNL water supply and distribution system provides water for process cooling, air conditioning, fire protection, and potable uses. Fourteen supply wells have been installed on-site to pump the groundwater from the underlying aquifer for such uses. Nine of these wells comprise SubAOC 15A-Potable/Supply Wells. Supply wells #1, 02, 010 and 011 are presently out of service due to volatile organic compound contamination. Well #3 is out of service due to the potential of drawing in contaminants from -the Central Steam Facility's contaminated groundwater plume. Supply wells 04, #6, #7, and #12 have had sporadic low concentrations of organic compounds.in the groundwater, but are still in service. Currently, supply wells 010 and #11 are in the process having carbon adsorption units installed to treat the organic contamination. In addition, SubAOC 15B -Monitoring well 130-02 area is also a receptor of the on- site groundwater contamination by organic compounds. In 1989, monitoring well 130-02, located at the southern site boundary, indicated organic concentrations which exceed state drinking water standards. In 1990, Suffolk County investigated the off-site occurence of organic contaminants. A current Suffolk County report concluded that an off-site industrial park was the principal source of the high organic concentrations found in residential wells, off-site. However,, BNL was also found to be a contributable source of contamination in the area at a greater depth off-site. However, it is not clear at this time whether BNL is responsible for the contamination in the off-site residential wells. BNL plans to remediate both subAOCs under the IAG, as part of Operable Unit III (see Table 1-2). Operable Unit III will be remediated under one RI/FS-EA program at BNL. K-46- 1.1.16 AOC 16- Aerial—Radioactive Mcnitorina Sv is am Results In 1980 and 1983, aerial radiation surveys conducted over the BNL site have indicated that in addition to the known sources of external radiation on-site, there were unanticipated locations where external exposure rates exceeded background levels. These areas were, investigated and the sources were determined to be cesium -137 contaminated soil located adjacent to or near the following buildings: Medical (Building 490); Chemistry (Building 555); Physics (Building 510); Contracts and Procurement (Building 355); LINAC (Building 930); Brookhaven Center (Building 30); Applied Math (Building 515); and the Criticality Facility Building 526). The areas of contaminated soil could not be directly related to past activities at the particular area. The source of the contaminated soils.is believed to have been from the Hazardous waste Management Facility where the soils were subjected to various spills of aged fission products stored at that location. The soil was mistakenly removed from the HWMF and spread at various locations on-site for landscaping purposes. Presently, the levels of exposure do not present a health hazard to employees on-site. BNL plans to remediate the AOC under the IAG, as part of Operable Unit VII (see Table 1-2). Operable Unit VII will be remediated under one RI/FS-EA program at BNL. 1.1.17 AOC 17- Area Adiacent to Former Low -Mass Criticality Facility The Area Adjacent to Former Low -Mass Criticality Facility was used from 1955 to 1967 as a testing silo for studying nuclear chain reactions of various materials over time after exposure to a portable radiation source. No accidents have been documented at the AOC as a result of such use. In 1967, the testing silo was decontaminated and decommissioned. The silo was later utilized for the storage of various non -hazardous equipment and tools. In 1983, twenty drums of ethylene dibromide were temporarily stored in the silo, until removed in 1984. No spillage occurred according to logbook records. The AOC was identified during the 1983 ground-based radiological survey as a location contaminated with cesium- 137 in the top surf icial soil. BNL plans to remediate the AOC under the IAG, as part of Operable Unit VII (see Table 1-2). Operable Unit VII will be remediated under one RI/FS-EA program at BNL. 1.1.18 AOC 18- Alternate Gradient Synchrotron (AGS) Scrapyard The Alternate Gradient Synchrotron (AGS) Department maintains two steel storage scrapyards. one yard is intended for the storage of steel contaminated by radioactivity and the other for non -activated steel. Some of the steel has been stored in the yards for more than 20 years and has rusted. The rust flakes have fallen to the ground and as a result radioactive particles of steel may have contaminated the soil. In 1989, radiological survey data indicates certain soil locations had elevated cesium -137 concentrations, previously identified in 1983. Trace levels of activation product were detected in the areas. Metals data indicate that outdoor storage of shield material results in increased metal concentrations in the soil. Groundwater monitoring wells in the area have shown minor concentrations of strontium -90, tritium, and sodium -22. The sodium -22 concentrations are probably related to AGS activities. No significant metal concentrations were found in the groundwater. Organic compounds were detected above state drinking water standards in 1989. However, organic contamination is probably not related to the AGS Scrapyard. BNL plans to reuse the steel in the scrapyards and to remediate the AOC under the IAG, as part of Operable Unit II (see Table 1-2). K-47 1.1.19 AOC 19- TCE Spill, Building T-1 During the years 1951 through 1953, the Physic Department's Cloud Chamber Group would discharge approximately five gallons of trichloroethylene and dry ice onto the ground surface. This practice was repeated every two days for two and half years. Due to the volatile nature of this chemical, most of it would have evaporated, and a very small percentage would have actually entered into the soil and eventually into the groundwater. In 1989, two groundwater monitoring wells were installed at the AOC. In 1989, the organic compound, 1,1,1 -trichloroethane, was detected above state drinking water standards in these wells. In addition, 1,1-dichloroethylene and tritium were detected in the wells. BNL plans to remediate the AOC under the IAG, as part of Operable Unit III (see Table 1-2). Operable Unit III will be remediated under one RI/FS-EA program at BNL. 1 1 20 AOC 20- Particle Beam Dump, North End of Linear Accelerator AOC 20 -Particle Beam Dump, North End of LINAC had three incidents of contamination to the environment. The first incident occurred in the 1950's when radiologically -contaminated landscaping soil were spread over the southern side of the northend of the LINAC. In 1974, outfall #006 located at the AOC, mistakenly discharged cooling water used in the BLIP and HEBT areas. The discharge was an isolated incident involving approximately twenty gallons of BLIP water to a wetland north of the LINAC. The radioactivity was low and the radionuclides had very short half-lives. More recently, in 1990, the same outfall discharged demineralized regeneration water from the LINAC into the wetland. Sampling efforts at the time indicated copper, lead, and other inorganic compounds detected in the sediments of the wetland. In 1989, radionuclides were detected in the discharge waters from the outfall. No current groundwater data is available. In 1985, the one groundwater monitoring well located at the AOC contained organic compound concentrations which exceeded state drinking water standards. BNL plans to remediate the AOC under the IAG, as part of Operable Unit VII (see Table 1-2). 1.1.21 AOC 21- Leaking Sewer Pipes The sewage system was intially built in 1917 and was upgraded and repaired in 1942 by the Army. The current system consists of 31 miles of underground tile drains, all of which eventually lead to the Sewage Treatment Plant. The sewer lines are a inadvertent source of groundwater recharge. Two studies of the system indicated 16% to 20% leakage occurring along cracks, broken pipes, and open joints in the system. The sewer lines have been a conduit for sanitary wastes, however, radioactive and hazardous waste from various labs have entered the system at times. Gross beta and 1 mCi/ml or less of tritium are released directly into the sewer system. BNL plans to remediate the sewer lines under the IAG, as part of various Operable Units, but mostly as part of Operable Unit III (see Table 1-2). These Operable Units will consist of various RI/FS-EA programs at BNL. 1.1.22 AOC 22- Old Firehouse In 1985, a routine radiological survey of the old firehouse area was conducted prior to its demolition. The investigation revealed an area of soil and concrete exhibiting elevated radiation. The soil and overlying concrete were removed and placed in drums for disposal. Soils were removed until residual exposure rates K-48 were at background levels. In 1989, two groundwater monitoring wells were installed at the AOC. Groundwater data, in 1989, indicated elevated levels above background of radionuclides, but below state drinking water standards. In addition, organic compounds were detected above state drinking water standards in the groundwater. BNL plans to remediate the AOC under the IAG, as part of Operable Unit III (see Table 1-2). Operable Unit III will be remediated under one RI/FS-EA program at BNL. 1.1.23 AOC 23- Offsite Tritium Plumes •Two offsite tritium plume areas have been attributed in part to documented releases from the Waste Concentration Facility to the Sewage Treatment Plant, as well as to other sources such as the Current Landfill, Hazardous Waste Management Facility and the Former Landfill Area. The accidental tritium releases to the Sewage Treatment Plant have resulted in a plume migrating to the east along the Peconic River Basin. The tritium plume associated with the Current Landfill, Former Landfill Area, and the Hazardous waste Management Facility migrates to the south-southeast. In late 1984 and early 1985 a groundwater contaminnant plume consisting of elevated concentrations of tritium was discovered on the eastern border of the BNL site. Tritium was detected in groundwater samples collected from off-site monitoring wells at levels exceeding allowable standards. Samples of off-site residential wells by Suffolk County and BNL contained low levels of tritium but at concentrations below state drinking water standards. BNL and Suffolk County authorities have established an intensive groundwater monitoring program which collects samples from select monitoring wells on-site and off-site residential wells on a regular basis. Since 1985, concentrations of tritium off- site have been below state drinking water standards. BNL plans to remediate the AOC under the IAG, as part of Operable Unit I and Operable Unit V (see Table 1- 2). 1.1.24 AOC 24- Process Supply wells 104 and 105 Two production supply wells, 0104 and 0105, on the BNL site have been designated as SubAOC 24A. These wells provide cooling water for the Medical Research Center's reactor. These wells have either shown a history of contamination or a threat of contamination by organic compounds. In addition, the recharge basin HP (Outfall 004) which discharges cooling water from the Medical Research Reactor has been designated as SubAOC 24B, since organic compounds were being discharged in violation of their SPDES permit. As a result, in 1990, the two wells were shutdown and all discharges to the recharge basin halted. Currently, BNL is studying the possibility of installing a treatment unit to well 0105. BNL plans to remediate the AOC under the IAG, as part of Operable Unit III (see Table 1-2). Operable Unit III will be remediated under one RI/FS-EA program at BNL.

Team - subcontractors to HALLIBURTON NUS under this contract are SEC Donohue Inc. and ENSR Consulting and Engineering. Contract Task Order (CTO) 0002 authorizes HALLIBURTON NUS to conduct a Site Investigation at the Naval Weapons Industrial Reserve Plant (NWIRP) at Calverton, Suffolk County, New York. The plant is located on Long Island, New York, and is operated by Grumman Aerospace Corporation (Grumman) (see Figures 1-1 and 1-2). 1.2 Purpose The objective of the SI is to obtain environmental information in order to: • Eliminate from further investigation those sites that pose no definable threat to the environment or to public health under CERCLA. • Collect data to develop a valid PA score for the sites. • Document the release or potential release of hazardous substances at each site and determine if additional action is required. 1.3 Scope of Work HALLIBURTON NUS was tasked to conduct a site investigation of the Navy's Calverton NWIRP. The need for this site investigation resulted from the findings of an Initial Assessment Study completed in December 1986 (Navy (U.S. Department of the Navy] 1986). This study identified six areas requiring additional investigation. Since this study, a seventh area was also considered for investigation because of fuel spills due to tank and equipment failure as well as human error. The fuel spills were identified as having occurred in the fuel depot area. These seven sites are as follows (see Figure 1-3).

NEW YORK Environmental Corporation SCALE IN FEET r �o 0 2000 4000 SCALE IN FEET 1-4 IVHAUBUBTON NUS Site 6C - South End of Runway 32-14 Site 7 - Fuel Depot Area To support the Site Investigation, HALLIBURTON NUS conducted sampling of surface and subsurface soils, groundwaters, sediments, surface waters, and free products. Based on historical data, indicating what types of contaminants that would be expected to be found at each site, the samples were analyzed for volatile organics or benzene, toluene, ethylbenzene, and xylene; semivolatile organics or polyaromatic hydrocarbons; metals and cyanide or lead; and/or pesticides/PCBs. 1.4 Summary As a follow-up to the U.S. Navy Initial Assessment Study performed in 1986, as well as additional findings since this time, seven sites were investigated at the NWIRP in Calverton, New York. These sites can be classified as either landfill -type sites or sites resulting from documented or suspected historic spills or leaks of fuels, oils, and/or solvents. The two landfill -type sites are the northeast pond disposal area (Site 1) and the picnic grounds disposal area (Site 4). There are no reports of hazardous material being disposed in either of these sites. The sites considered because of documented or suspected spills or leaks are the fire training area (Site 2), the fuel calibration area (Site 6A), the engine runup area (Site 6B), the south end of Runway 32-14 (Site 6C), and the fuel depot area (Site 7). The presence of free floating products in monitoring wells installed at Sites 2, 6A, and 7, is a direct indication of historic spills or leaks. Site 6B, Site 6C, and the engine runup area and engine test house at Site 6A were considered because of the visual observation of stressed vegetation at these areas. These areas with stressed vegetation correlate to the locations where the exhaust from jet engines are common. The volatile organics compounds found at one or more of the sites include chlorinated alkanes (e.g., 1,1,1 -trichloroethane), chlorinated alkenes (e.g., tetrachloroethene), and aromatic compounds (e.g., benzene and toluene). The semivolatile organic compounds found at one or more of the sites include phthalates and polyaromatic hydrocarbons. The inorganic compounds found at concentration above natural background concentration at one or more sites include chromium, cadmium, lead, copper, zinc, and cyanide. The most significant contaminants detected in the soils at Site 1 include naphthalene (1,700J ug/kg), PAHs (182,500J ug/kg), cadmium (42.4 mg/kg), chromium (959 mg/kg), copper (1,320J mg/kg),. lead (314J mg/kg), nickel (233 mg/kg), and zinc (2,3801 mg/kg). Low concentrations of surface water and sediment contamination were also found. L-10 The most significant contaminants detected in the soils at Site 2 include chloroethane (230J ug/kg),'tetrachloroethene (580 ug/kg), toluene (4,300 ug/kg), ethylbenzene (1,500 ug/kg), PAHs (31,310J ug/kg), aldrin (36 ug/kg), PCBs (8,500 -ug/kg), and lead (41.6J mg/kg). The most significant contaminants detected in the groundwater at Site 2 include chloroethane (4,500 ug/1), 1,1- dichloroethane (1,700 ug/1), toluene (320 ug/1), 1,2 - dichlorobenzene (74 ug/1), PCBs (7.9 ug/1), Cadmium (22.8 ug/1), chromium (80.3 ug/1), lead (73.8 ug/1), and zinc (1,290 ug/1). Minimal contamination was found at_Site 4. The most significant contaminants detected in the soils at Site. 4 include 1,2- dichloroethane (7 ug/kg) and lead (21.3 mg/kg). The most significant contaminants detected in the soils at Site 6A include 1,1,1 -trichloroethane (7,400) ug/kg), toluene (1,300J ug/kg), xylene (17,000J ug/kg), and lead (21.2J mg/kg). The most significant contaminants detected in the groundwater at Site 6A include chloroethane (2,600 ug/1), 1,1-dichloroethane (300 ug/1), 1,1,1 -trichloroethane (23 ug/1), toluene (140 ug/1), and lead (1,740 ug/1). Minimal contamination was found in the sediments at this site. Minimal contamination was found at Sites 6B and 6C. The most significant contaminant detected was PAHs (493J ug/kg). Minimal contamination was found in the soils at Site 7. The most significant contaminant detected was PAHs (4,750J ug/kg). However more significant groundwater contamination was found. The groundwater contaminants include benzene (390 ug/1), toluene (540 ug/1), xylene (960 ug/1), and lead (692 ug/1). Low, but significant, concentrations of several volatile organics were found in the production well water. These contaminants include 1,1-dichloroethane (3J ug/1) and 1,1,1 -trichloroethane (5 ug/1) . Based on this Site Investigation Study, it is� recommended that additional investigation be conducted to quantify the nature and extent of contamination as well as the risks to human health and the environment for the following media and sites: • The soils at Sites 1, 2, and 6A (except for the engine runup area and the engine test house), and potentially Site 7. • The groundwater at Sites 1, 2, 6A (except for the engine runup area and the engine test house), and Site 7. • The sediments and surface water at Site 1. L-11 1 -4 -� • The soils (including the former coal pile) and contaminated groundwater associated with the Production Wells. Additional investigations of past practices should also be ._ conducted to evaluate other potential source areas of contamination, including abandoned leach fields throughout the NWIRP. No additional investigation is recommended for the following areas: • Site 4. • The engine runup area and engine test house at Site 6A. • Sites 6B and 6C. r� a L-12
