" I ' iv GEOHYDROLOGY AND 1985 GROUND-WATER LEVELS ON MANHASSET NECK, LONG ISLAND, NEW YORK by Robert N. Casson Abstract Manhasset Neck, a 13.4-square-mile peninsula on the north shore of Nassau County., N.Y. , consists of unconsolidated Pleistocene and Cretaceous sediments overlying a basement complex of Precambrian an&(or)� early Paleozoic age.. -It also contains beach, bog, and marsh deposits -of Holocene age.' A glacial advance during the Woodfdrdian 'Substage caused deformation and displacement of Pleistocene 'and Cretaceous material. Cretaceous material overlies bedrock in the southern half of the peninsula but is generally absent in the northern half. The Cretaceous material forms the Lloyd and Magothy aquifers, which are separated by the Raritan confining unit. The northern half of Manhasset Neck contains the upper Pleistocene Port Washington, confining unit, underlain, by the Port Washington aquifer, which unconformably overlies 'bedrock. the upper glacial 'aquifer, also of late Pleistocene age., overlies the entire ven,ins.ui'a. An upward bulge of the "ice-shoved" Port Washington confining unit maintains- an anomalously' high water table near the" center of Manhasset Neck. �_J INTRODUCTION All freshwater for public supply and industrial, agricultural, and c6nfmorcial use in central and eastern Long Island is ground water. Eastward urbanization on the island, particularly since the 1950's, has placed an increasing demand on the ground-water resources. Manhasset Neck, a 13..4-mi2 (square-mile) peninsula in the Town of North Hempstead, Nassau County (fig. 1) , has a population of 39,000. Because little is, known about the geohydrologic environment, development and "management of the ground-water resources. for future demand requires a detailed description of the goohydrologic setting. Irr, 19'85, the U.S. Geological Survey, in cooperation with the Nassau --County Department of Publi6 Works,, studied Manhasset Neck to document the 'gephy-4rology and 'define ro.�und-water levels: Purpose and Scope This- report describes the geohydrology and 1985 ground-water levels on -Marihasset- Neck. It includes (1) maps showing the surface altitude and thickness of the aquifers and confining units; (2) four vertical sect-ions that 1 depict the positions of these hydtogeolog'ic units, and (3) water-table and ,po,tentiom6t-ric-surf ace :maps of the aquifers.

Y. 2 Location and Extent of Area The Area investigated is a 13,.4-mi2 peninsula in the Town of North Hempstead in northern Nassau County. it is bounded on the west, north,' and east by Manhasset Harbor, Long IslandSound, and Hempstead Harbor, respectively.,, and by Northern Boulevard on the south (fig. 1) . Geologic History A deta-iled description of Long Island's geologic history is presented in Fuller (1914) . Recent evidence has prompted a reinterpretation of the island's glacial history, however, which is given in Sirkin (1982) . II 'Oliver and Drake (1951) , in a seismic study of the Long Island area, demonstrate. that the Precambrian and (or) early Paleozoic bedrock surface has top.o;grdphic irregularities that are indicative of subareal erosion. This period of erosion may have begun in the Late Triassic Period and extend-ed. into the Jurassic. A mid-Cretaceous uplift of the earth's crust, centered along the axis of the Appalachian Mountains, subsequently created highlands to the west and north of Long Island in northern New York, Vermont,. and New Hampshire while depressing, the Long Island area. southeastward. This orogenic movement provi(f6d a source of sediment that was subsequently deposited- in the. Long Island Area as the Raritan Formation and Magothy Formation and Matawan Group, undifferentiated. Grain-size analysisof h' t e s 0 Cretaceous sediments indicates an estuarine or deltaic environment of deposition (Mills.. and Wellsi 1974). The southeastward thickening' of the Cretaceous formations indicates renewed tilting of the bedrock (Swarzenski, 1963) . Regression of the sea at the close of the Cretaceous Period is indicated by a lack of Tertiary strata and the pr osence of troughs that seem to be river valleys cut into Cretaceous :sediment. The depression. that now forms Long Island Sound probably originated as an east-west-trending subsequent river valley, the southern extent of which is represented by a cuestalike ridge cut into the Cretaceous formations (Swarzenski,, 1963) . A Pleistocene periglacial deflation surface, as indicated by quartz ventifacts in the top of Cretaceous sediment at the Fort Washington sand pits 'near the- east-,central shore of the peninsula, resulted from the ensuing glacial Activity (Mills And Wells, 1974). A new conceptual model for the glaciation of this region, has been developed in res°ponse.. to evidence of a nonglacial interval and subsequent high stand of the sea during the. mid7Wisconsinan Stage between the emplacement of. two drift sheets .(Sirkin, 198 2) . The e'arlier of these drift sheets consists of the Flower Hill sand and. West Shore till units of the Manhasset Formation that forms the Port Washington aquifer and was deposited during the first glacial advance, which apparent:ly occurred during the-Altonian Substage (Sirkim, 1982.) . This deposit seems to be derived largely ly from a Cretaceous source because it contains only 'minor min6r amount of erratic material. The second drift sheet consists of the Hempstead sand and Roslyn till units of the East Hills Formation that :forms the. upper glacial aquifer and was deposited during the second glacial advance during the Woodfordlan Substage (,Sirkin, 1982) . Ice-shove tectonics during this time resulted in the deformation and displacement of Cretaceous and Pleistocene sediments (Mills and Wells, 1974) . 3 At the end of glaciation in the Woodfordian Substage (Sirkin, 1982) approximately 18,000 years ago, sea level began to rise to its .present level. jConsequently, recent deposition of Holocene acre consisting of shore, stream, I� valley, swamp, lake, bog, and marsh deposits has occurred. Previous investigations The geology and ground-water resources of Nassau County were described by Perlmutter and Geraghty (1963) , Swarzenski -(1963)-, Isbister (1966), and Kilburn (197-9). The .reports by Swarzenski and Kilburn provided information pertinent to Manhasset Neck such as historic water-lev'el data and contour maps. The glacial deformation of the area was described by .Mills and Wells . _ (1974) . Sirkin (198'2) described the surficial• geology, geologic history, geologic nomenclature, and correlation of `Pleistocene deposits on Long Island. - Perlmutter and Todd (1965) and Sirkin ,(1974) discussed the correlation of Grer.aceous strata. Methods of Investigation Drillers' and geologists' lithologic strip logs of the earth material Penetrated were compared for correlation purposes. Many of these logs represent observation wells suitable for water-level measurements. Gamma logs from some wells were available to verify drillers' or geologists' interpre- tations. Locations of wells and test holes are shown on plate 1. Data on ,ground-water levels collected from 1950 through May 19-85;were analyzed. (The most recent water:level :measurements were made during this stud on,Ma 29-31 1985. Because the water levels in the dee y, y , ) p, confined aquifers (Lloyd 'and Port Washington aquifers) change in response to tidal variations, all measurements were made at high tide for consistency. In --• addition, all public-supply wells were measured after a shutdown period of at least 12 hours to allow recovery, except for Lloyd well N1715 in the central part of Manhasset Neck (pl. 1), which had been running for 24 hours. As such, the- potentiometric 'surface is not static but reflects the degree of c'onf'ini inient of the' Lloyd, aquifer,; as evidenced by the `far-reaching effects of the stress .placed• on it by withdrawal. GEOHYDROLOGY Long Island- is underlain by unconsolidated sediments of Quaternary and Cretaceous age resting on a bedrock surface of Precambrian and (or) early Paleozoic age. Material of the Cretaceous Period consists of the Raritan Formation, which is composed of a lower Lloyd Sand Member and an upper unnamed clay member, and the Magothy Formation and Matawan Group, undifferentiated. I The Pleistpeenee -material consists of two sand units, the Manhasset Formation and SirkiYi's (1982). East Hills Formation, separated by a marine clay unit. Pleistocene stratigraphy of Long Island has been the subject of much confusion. Fuller (1914). terms the lower sand unit and middle clay unit of —' Manhasset Neck the Jameco Gravel and Gardiners Clay, respectively. A 4 ,pre-Wisconsinan age is suggested for the Jameco Gravel, whereas the Gardiners Clay is. thought "to represent the later Sangamon interglaciation (.Fuller, 1954) . Kilburn (1979") suggests the -names Port Washington aquifer and Port Washington confining unit for the Jameco Gravel and Gardiners Clay on Manhasset Neck, respectively, on the grounds that the names Jameco Gravel and Gardiners Clay imply a questionable correlation with other units of that - " designation in other parts of Long Island. Recent studies by Sirkin (1982) suggest that Fuller's middle clay unit (which Sirkin designates marine clay) , herein referred to as the Port Washington confining unit, represents a warm interval and a relatively high stand of, the sea during the mid-Wisconsinan Stage. This warm interval occurred between the emplacement of two .drift - sheets, hereafter referred to as the Port Washington aquifer and" upper glacial aquifer, for -the lower and upper sand units, r.espectively". _ The question, .of stratigraphic correlation is not of paramount importance here because .the upper and lower boundaries of hydrogeologic units are determined by litho'logy, not by age. For example, the top of the Port Washington con-fining unit is distinguished from the upper glacial aquifer 'by .a change from sand to clay, which may not have time-stratigraphic s"i'gnificance.

Paleozoic and (or) Bedrock Bedrock Precambrian 5 -i 1 T Recent Deposits Recent -deposits of Holocene age consist of sand and g gravel that forms beaches and bars and' silty alluvium deposited by streams. Organic silt in freshwater swamps and peat bogs apparently represents continuous deposition since early postglacial time (Swarzenaki, 1963) . Swarzenski (1963.) notes an age of 5,340 ± 240 year BP (before present) --for partly lignitized plant debris - from a humus and peat deposit overlying and in contact with till in the study area. i Clay and silt deposits beneath Long Island Sound and' the bays that flank Manhasset Neck' are important hydrologically because they retard the downward movement of saltwater and thus inhibit its movement into Manhasset Neck's ga round-wter reservoir. l Upper Glacial Aquifer The upper glacial aquifer forms the present land surface on 'Manhasset Neck except in areas that have experienced recent deposition; such as the. shore and.- its bays,, ma'r'shes, bogs., lakes.,. and streams. The upper glacial aquifer includes both the unsaturated and saturated parts of the upper Pleistocene deposits. As shown, in -plate 2- these deposits overlie the Port Washington confining unit In the northern half of Manhasset Neck and overlie i_ the Magothy Formation in the southern part. If Drillers' and geologists' logs indicate that the deposits consist of beds of brownish, fine to coarse stratified sand and gravel and unstratified - mixtures, of clay and boulder till. Freshwater-lake deposits _consisting of Silt., clay, lignite,. and pyrite nodules are also present locally. j f - The upper glacial aquifer in the study area conforms to the moraine, 'area of Swarzenski (,1'963) , who erroneously divided the upper Pleistocene deposits of Long Island into a northern moraine area and a southern area of glacial f outwash. Sirkin 1982 classifies the kamic stratified sand and - ( ) grave"1 and the gravel and. unstratified clay and boulder mixture on Manhasset Neck as, .the "Hempstead- sand. and, Roslyn till- units, respectively, of his Woodfordian East M Hills Formation. Furthermore, as demonstrated by Mills and Wells (,1974), the Tate Wisconsin ice: advance- caused large-scale folding and thrust faulting, of_ the previously deposited Cretaceous and Pleistocene material:. The top of the upper glacial aquifer .ranges from approximately 2.00, ft above- to 140 ft below s'ea 1eve1; its thickness ranges from 0 to approximately 340 ft. The vertical sections in plate 2 'show its position in relation to the ;richer ggohydrologic unfits. Port Washington Confining Unit The name Port Washington confining unit was introduced by Kilburn (1979) to -avoid the use of the name Gardiners Clay, which would cause confusion in correlations. In some locations this unit contains fossil oyster and clam shells _arid foraminifera, of which ELph-idi-um is the most common genus. Radio- carbon age determinations of oyster-shell fragments by the U.S. Geological 6 j I . 7 Survey And, reported by Swarzenski (.1.963) indicate, an age greater than 38z,,000 years,. 'S,i.rkin (1982) reports 4 range in age from 43,,,000 to 21,150 BP for A sequence of marine clay;, salt- and freshwater peat, and oyst'er-reef ibeds that occur within this unit At the 'Port Washington sand pits in the east-central part of 'Manhasset Neck (fag. 1) . The Port Washington' � .confining Unit., overlies the Port Washington aquife'r and is in turn overlain by the upper glacial aquifer. insofar as it abuts the Cretaceous deposits on its south side (pl. 2, section D-Dt) ,, Suter and .others '(1 949), correlated it with the Raritan Formation; Kilburn (1979) states that this unit probably contains local remnants of the Raritan, Formation. In addition, clayeytill and clay/silt of glacial origin are present within this unit in the. ",glacial tectonic" manner suggested by Mills and Wells (1974) . The top of the -Port W"hlngton confining. unit ranges from 104 ft 'above' to, 150 ft below s.da level (fi, - A And its thickness. ranges from .30. to 264. ft. g,, :2 (11"g. 2,B). The vertical 3. sections in 'p'late 2 show its Position in relation, to e the, other geohyd-rolog,,ic units In ,th5e area; it Drillers' and geologists, logs indicate this unit to consist of gray and gteenish-brown c1ay And silt, in addition to the fossiliferous material and nt4 one previously. It alsoc.ont,,Ains- s.cattered lenses of sand. or :sand and gravel Port Washington Aquifer L The name Port Washington aquifer was first used for the area by Kilburn (1979) in preference to the name Jameco Gravel, which would imply a correlation with Jameco deposits in southern Queens and southwestern Nassau Counties. Furthermore, Swarzenski (1963) noted that this deposit, which has not been reliably dated, seems to be -derived largely from a Cretaceous source and -thus, contains only a small, amount of erratic material,, such, as igneous rock pebbles.,. that characterize the Jameco on the, south shore. More recent -studies by Sirkin (1982Y suggest that this Quaternary unit, which was, Previously hypothesized to represent a pre-Wisconsinan glacial deposit, is i probably representative of the Altonian Substage of the` Wisconsinan Stage. The.. Port- Washington Aquifer is ,present only- in the morthe-rn half of Manhasset 'Neck, where it 'Lies upon. the bedrock surface and is in 'turn over- lain by a clay Unit termad -the Port Washington confining unit '(Kilburn, 1579) In the, southern part, it abuts the buried Cretaceous cuesta. Kilburn (1979)' nates thAt -riot all Cretaceous deposits, wer-e- removed from the area north of their inferred limits; thus, erosional remnants of Cretaceous material could be -present between the Pleistocene deposits and the bedrock in this area. The, top .of the Port Washington aquifer ranges from Approximately 15 ft to 27.5 ft below. sea level (fig.,, 3-A); its thickness ranges from 0 to 140 ft (fig. 3B) . The vertical sections in 'plate 2 show its position in relation to the other hydrogeologic units in the area. j . Drillers' and geologists, logs indicate that this unit is composed mainly of •sand or sand and gravel with varying amounts of interbedded clay, silt, and sandy clay. It generally is brownish which helps to distinguish it from the whitish .Cretaceous sediment.. 7 Magothy Aquifer The Magothy aquifer, which, consists,,, of Upper Cretaceous sediment of the Magothy Formation and Matawan Group,,, undifferentiated, overlies, the Raritan, For'mation, and is, in turn overlain, by Pleistocene glacial deposits. The altitude of the top of 'the Magothy 11 on Manhas-set Neck ranges from 53 ff, ,ab6ve to 173' ft below sea level ("fig. 4A); thickness ranges from 0 to 311 ft fig. 4:B) . Together with the underlying Cre'taceous Raritan Formation it forms an erbs,i,ondl feature resembling a buriedcuesta (pl. 2, section A-,M) And thus is from the 'rid.r.thern half of the area. Plate 2 also shows the position. of 'the, Mag6thy aquif et,, in relart,ion- to the other geohydrologic. units in the area. Drillers' and -geologists,' logs, typically Indicate a fining upward sequence of gralln size. A greater proportion of gravel is common in, the lower -the formation, whereas clay and sandy clay predominate in the upper half of lj half. The coarser, lower zone is commonly referred to in the literature as basal'- Ma-gothy. The chief -constituent is fine micaceous quartz sand, generally- white,, although gray, pink, or red sediment is common. The Magothy aquifer Is the principal aquifer throughout most of Long IsAand., including Manhasset Neck. Raritan Confi-ni,ng Unit The R,qr#an confining 14n�I it., which consists of the unnamed clay member of "the Raritan: Formation, lies between the Lloyd- and Mago.thy aquifers and acts as a confining unit, to the underlying Lloyd aquifer. Like the Lloyd aquifer below- it- dips and thickens, southeastward. The altitude of the top of the Raritan ranges from 150 to 275 ft below sea level (fig. 5A) , and its thickness ranges from 25 to 140 ft (fig. 5B) . The position of the Raritan confining confining unit in relation to the other geohydrologic units is shown in the vertical sections in plate 2. Drillers' acid- geologists' logs describe the material as a relatively Impermeable solid and silty clay that can be light to- dark gray, red., white, yelloV, or mottled. Laminations as well. as pyrite and lenses of lignite are present in some, cores. Ldyd Aquifer Overlying the bedrock is .the L,Iloyo, aquif er, which dons,ists� of the Lloyd Sand Member of the Upper Cretaceous Raritan Formation. As, in the bedrock below, its upper surface 'has a general -southeastwatd. dip,, as. indicated by the 109,81 of 1S wells drilled into this member (fig. 6A). The altitude of the top of the Lloyd ranges from approximately 200 to 400 ft below sea level-, and the thickness is generally 150 ft (fig. 6B) . It is absent from the northern half of the, study Lare,a., where it abuts Pleistocene deposits, as shown in figures 6A and, 6B and the vertical sections in plate _Z. Dr- illers' and geologists, logs indicate that L.loyd material .conslsts _of yellow, white, and gray subangular to subrounded quartz with minor amount!§� of chert and other stable minerals; it also contains interstitial clay as well as lenses of -white, gray, or multicolored clay that cannot be correlated over significant distances. Lignite is present as scattered particles or thin ic S m es.. Grain-size analyses suggest an estuarine or deltaic depositional environment (Mills and Vell's, 1974) . Be4rqck The bedrock surface in the study area lies 'between 166 ft and 400 it below sea level :(fig, 7) . The exact depth of the bedrock is difficult to distinguish in logs because its. surface is weathered. to S ApProl.ite. Drillers' and, gqologis_ts'l in't.erpxe.tatioh bf-the weathered su-r-face is based :upon residual -ted,. &ray�, yellowv. ,1,ihJ'*te,y green,, or- mottled clay or,-partly decayed. rotk6nd mineral fragments. Quartz, garnet, biotite; amphihola, andf'elds chalract.erize the mine'ral-fra " par piebt assemblage; which seems indicative' of A .b,iotite schist*. or gneiss -with p6ssible granitic' or pegm' atitic Intrusives (Perlmutter end -Geraghty, 1963) , Thb -bddrock-sur-face altitude and configuration are of interest because -t'he bedrock essentially forms the base of the ground-water reservoir. Although joitts and fractures in the bedrock could possibly provide yields suitable for limited domestic supply, no wells obtain water from this source in ,the study area at present. The 11 wells and 4 test holes that have been drilled into bedrock in the ,study area (fig. 1) define a southeastward dip except for well N314, at the -northern end of the peninsula., .which I indicates a local northwestwarddip (-Igo Value on. fig. 7). Although the limited well data can -indicate only the general trend of the bedrock. surface, Olivet and Drake (1551.), 'in a seismic study of the Long Island area, found indications of: 20o -to .300 ft of bedrock thus$ the bedrock 'surface clearly is not a classic ponepj4in. OROUND"WATER' LEVELS Th e, circulation of water, from the earth's surface to the atmosphere by evaporation and transpiration and its subsequent return as precipitation c, constitutes the hydrologic cycle. Of the total precipitation that falls- on Manhasset Neck, ck, part returns to the atmosphere through evapotranspiration, part runs overland to stream that discharge to Long Island Sound, and the remainder, approximately 50 -percent, infiltrates the ground to the zone of saturation, where it, becomes part of Manhasset Neckl:s, oil r, nd-water system. g UPPe r a I aci I Aquifer The, water table lies generally within the upper glacial aquifer on Manhasset Neck. Its configuration is essentially controlled by the lbmd.7•§urfAc6f 'tdpogr4phyi the wat�er-�traftsmi,.tt,ing ,pr.operties of the upper Yleisto6ene deposits in -wh i ch. ;it liesand, -of the. geohydrologic, units below; and, the Iodation and amount of pumping from wells- screened. within Manhasset NeWs, geohydrolodc units: 9 I , I Water-level measurements made at 32 wells throughout Manhass.et Neck on May 29-31, 1985, were used to construct the water-table map shown in figure 8A. The maximum water-table altitude in the area was 110 ft above sea level near the center of Manhasset Neck. Section A-Al (pl. 2) shows a bulge in the Port Washington confining unit near the center of the study area; this bulge { seems to. retard the northward flow of ground water. An increase in head is needed for water to permeate the confining unit and continue its northward flow,. which begins approximately 3 miles to the south at Long Island's - , regional ground-water divide (fig. 1) . This anomaly gives the geohydrologic system of Manhasset Neck a degree of complexity that is not found elsewhere on Long Island. Magothy Aquifer The Magothy aquifer (fig. 8B) is the major source of, water for Manhasset Neck as well as the rest of Long Island. It underlies the upper glacial aquifer and is hydraulically continuous with It. The major criterion for differentiating the Magothy from the upper glacial aquifer above is its finer j sediment size. The Magothy also is in hydraulic contact with the Port Washington aquifer (pl. 2) . Its general fining upwards sequence suggests that it is confined at depth. The Port Washington confining unit provides increased confinement in the northern part of the area (pl. 2, section D-DI) . Water-level data were collected on May 29-31, 1985, from seven wells screened within the Magothy aquifer. The distribution of hydrostatic heads (fig. 8B and pl. 2) indicates a downward vertical flow gradient from the upper glacial aquifer above at Manhasset Neck's central and southeastern areas of !-- recharge. The potentiometric-surface altitude ranges from 39 ft to 10 ft Above sea level at the south-central and southwestern parts of the Manhasset Neck, respectively. Port Washington Aquifer The Port Washington aquifer and the Lloyd aquifer together form what has j been described in the literature as the deep confined aquifer because of the probable lateral connection between the two units (Swarzenski, 1963). Water-level data from only it wells screened within the unit were available for construction of the potentiometric-surface contours shown in figure 8C. The vertical sections in plate 2 indicate flowing wells along the shores of the study area, where hydrostatic heads of the aquifer are higher than the land surface. Recharge from upper units through the Port Washington confining unit in inland areas is possible because the hydrostatic heads above are approximately 60 ft greater. The altitude of the potentiometric surface ranges from 27 ft above sea level near the central part of the study area to almost 1 ft below sea level at the western shore. 10 -- Lloyd Aquifer The Lloyd aquifer is the most confined unit in the study area and thus probably is the least .contaminated source of water, as well as the most unstable in terms of pumping interference. - Water-level data obtained on May 29-31, 1985 from nine wells screened Within the unit were used to construct the poteatiometric-surface map in figure 8D. The dynamic equilibrium of the unit under natural conditions has been altered by pumping from public-supply well N1715. The relation between hydrostatic heads in the Lloyd aquifer and those of the other aquifers is i shown in the vertical sections in plate 2. As shown in plate 2 and figure 8D, the Lloyd aquifer has a potential for saltwater encroachment where its potentiometric surface is below sea level near the western shore of the peninsula. The highest potentiometric-surface altitude on Manhasset Neck is -� 14 ft above sea level at the east shore (p1. 2, section D-Dl). SUMMARY AND CONCLUSIONS Manhasset Neck is composed of unconsolidated sediments of Pleistocene and _ Cretaceous age resting on a Precambrian and (or) early Paleozoic bedrock surface. A late Wisconsinan ice advance produced extensive folding and thrust faulting of Cretaceous and Pleistocene material that makes the geohydrologic environment anomalously complex for Long Island. Upper Cretaceous material (which overlies bedrock in the southern half of the study area but is generally absent from the northern half) forms the Raritan Formation and Magothy Formation and Matawan Group, undifferentiated. The Raritan Formation consists of the Lloyd Sand Member (the Lloyd aquifer) and an overlying unnamed clay member (the Raritan confining unit) . The Magothy Formation and Matawan Group, undifferentiated, forms the Magothy aquifer, which overlies the Raritan confining unit. The Port Washington aquifer and overlying Port Washington confining unit, both upper Pleistocene in age, are present beneath the northern half of the peninsula, where they overlie bedrock and abut the Cretaceous material to the south. Overlying these units throughout the area is the upper glacial aquifer, also of upper Pleistocene age. The upper glacial aquifer forms the present land surface except in areas of recent deposits of Holocene age, such as the shore and its bays, and marshes, bogs, lakes, and streams. Water-level data reveal a relatively high water table for Long Island near the center of Manhasset Neck; this is probably the result of an upward bulge in the underlying "ice-shoved" Port Washington confining unit.

Appendix 1 I I _ ' Selected Resumes......................................................................... Appendix 2 r- -I i I R & C Formation, Ltd. PHILOSOPHY R&C Formation,Ltd.was founded in recognition of a fundamental truth. Reality ultimately dictates the I final result. We realize that the final result of our professional services and advice,the quality of our product,and the satisfaction of our clients,is based upon the practice of five basic variables.These variables define our personality and"back to basics"approach. 1 ' UNDERSTANDING CLIENTS'PROBLEM AND NEED Defining exactly what is required by a client will target an appropriate scope of work,reducing - unnecessary and costly investigative clutter. GOOD SCIENCE Environmental consulting is applied science and"good science"necessitates scientific method; the methodological application of principles characteristic of an investigation(identification, experimentation and validation). Advice must be based upon valid rationale. SUBJECT KNOWLEDGE i Environmental consulting demands a knowledge of various fields of science,however,each project requires personnel with expertise in a select area. Good hydrogeological advice does not usually come from a toxicologist, and vice-versa. Knowledge must be continuously cultivated and each project must be performed by appropriate individuals. PROJECT MANAGEMENT Maintaining a strictly defined scope of work is essential. This scope of work should include only tasks germane to solving a clients specific problem and satisfying specific requests. Fellow employees should be managed as a resource by recognizing their individual skills and making them aware of the project's purpose and scope. Creative powers are to be encouraged......two heads are better than one." CLIENT COMMUNICATION J I Clients should always be informed of the ongoingrP ogress of projects. Upon completion,the work product(e.g.,report)should convey the performed scope of work concisely,making the nature of the investigation,conclusions and recommendations evident and understandable. The singularly most important common denominator underlying these basic variables is imagination. The - ability to confront a task creatively;to envision the appropriate steps and path of an investigation and the far-reaching effects of statements made,and advice given. 1 i ' it R & C Formation, Ltd. it SERVICE CAPABILITIES R&C Formation, Ltd. is a privately owned corporation specifically designed to provide advanced-quality, cost-effective professional groundwater and environmental services to our valued clientele.
