CHAPTER ONE
EXECUTIVE SUMMARY, CONCLUSIONS AND RECOMMENDATIONS
Executive Summary
The purpose of this study and report is to provide, the Fishers
Island Conservancy, the Suffolk County Health Department and the Suffolk
County Planning Department with technical information and recommendations
for development of rules, regulations and policies for the future
preservation of water quality in the three surface water reservoirs and
thE groundwater aquifers of the Fishers Island public water supply.
The work includes a watershed sanitary survey to identify existing
and future potential pollution sources. In order to definitively evaluate
risks presented by the identified potential contamination sources, the
Bar low Pond I nf il trat ion Gallery (underdrai n) was located and mapped in
addition to potential pollution sources within the watersheds and aquifers
of the public water supply. Test borings and monitor wells were installed
to determine groundwater flow patterns. Surface water quality and
quantity were determined in the field. This data was used to determine
tl,. water available from existing sources {reservoirs and wellsJ, wells
only, and surface supply for a year having an average rainfall and one for
a one hundred year frequency drought. System demand for these analyses
were then compared to the 2015 requirements.
CO'lcl us ions
As a result of the data provided by the Fishers Island Conservancy
and Fishers Island Water Works, the Suffolk County Health Department and
our analysis of the water quality data developed during this study, we
conclude as follows:
1. The surface water treatment plant must remain on stand by.

2. The reservoir watersheds have low density seasonally occupied
development. There are seventeen (17) residences located within the
watersheds and four (4) in the aquifer which have the potential to
contaminate the public water supply. These potential sources of
contamination are listed in Tables 8-1, 8-2, 8-3, and 8-4. The location
of the identified potential contamination sources are shown on Figure 5-1.
3. The present surface and groundwater quality is typical of water
sources in areas of low density development. EPA 502.2 analysis for 63
Volatile Organic Chemicals yielded negative results at the detection
limits specified for all surface and groundwaters sampled.
4. The laboratory analysis for Pesticides and Herbicides yielded negative
results at the detection limits for the contaminants specified in the
scope of stud:,'.
5. Water from Barlow Pond, Middle Farms Pond and Island Pond flows into
the groundwater during years with average to above average rainfall.
6. The Barlow Pond infiltration Gallery has a watershed area of One
Hundred Twenty-Seven (127) acres. It lies about two (2) feet above mean
sea level, passes under a number of glacial kettle holes and appears to be
well situated to intercept groundwater flowing seaward from the Isabella
Bluffs area. Flow from the gallery can be controlled by a valve in
Manhole Number 2 near Barlow Pond.
Re comme nda ti ons
It is recommended that the following actions be undertaken:
1. Establish a comprehensive and vigorous watershed and aquifer
monitoring, protection and spill prevention plan.
2. Prepare an emergency plan for dealing with contamination of the
groundwater or surface supplies.

5. Replace the missing manhole covers on the Barlow Pond Infiltration
Gallery with locking frames and covers.
Additional Environmental Issues
Several issues have been raised regarding environmental
investigations on Fishers Island since the scope of this report was
defined and established in our contract. These issues include additional
evaluations of the following items listed in order of watershed
rrQtecti~~!supply importance:
1. Surface area tributary to the wellfield and potential sources of
1)(Jl:u~ion within tllis area.
2. Ana::;cis of monthly billed water, metered production, population,
leakage, and other factors influencing historic and future monthly and
annual water demand.
3. Br;cki~rd Pend as potential source of surface water supply
augmentation.
4. The Barlow Pond Infiltration Gallery yield and the influence, if any,
of the pond near the Chip Dupont residence.
5. The potential pollution of the Barlow Pond Infiltration Gallery by the
Pickett Landfill.
6. "SIMA" well impacts on adjacent wetlands.

CHAPTER THREE
WATER BUDGET AND DESCRIPTION OF EXISTING WATER SUPPLY SYSTEM
Water Supply System
The Fishers Island Water WDrks System was cDnstructed in the early
1900's tD prDvide pDtable water and fire prDtectiDn fDr the Island.
The system services apprDximately 600 custDmers utilizing 22 miles Df
water n~ins, an equalizatiDn reservDir, a surface water treatment plant, a
groundwater treatment facility, a well field and three surface water
:e3ervoirs. There are no darns.
The SDurces Df surface water include BarlDw PDnd, Middle Farms PDnd
and Treasure PDnd. BarlDw PDnd has been augmented in the past, especially
doring the 1960's drDught by transferring water frDm Middle Farms PDnd
using temporary pipes and pumps. Water is pumped directly frDm BarlDw
Pond into the treatment plant.
The one (1) milliDn gallon per day surface water treatment plant
Wa5 constructed during the 1920's. The treatment process includes
aeration, cDagulation, sedimentation, filtration, pH adjustment and
disinfection. However, it was removed from service during 1990 and is Dn
stand..by. The plant is located adjacent to, and draws its supply from
Barlow Pond,
The sources of grDundwater supply include the "SIMA" well, the
"Church" well and the "Hers" well. The well water is Df gDDd quality
except fDr its iron cDntent which is relatively high. IrDn effects water
taste and odor and can clog well screens. IrDn also stains laundry and
plumbing fixtures.
A groundwater treatment facility was recently cDnstructed near
the Middle Farms Flats well field area. This facility provides pH
3-1
adjustment, sequestering of iron and manganese, and disinfection. The
treated water is pumped directly into the existing 10" main in East End
Road. The well water can be pumped to Middle Farms Pond to augment the
surface supply.
The distribution system consists of mostly unlined cast iron mains, a
small portion of asbestos cement pipe and about 2,800 feet of recently
installed PVC pipe. The 500,000 gallon Chocomount Reservoir maintains
the system pressure and provides fire storage.
T~e recent demand on the well field system has been reported by the
system operator as 75,000 gallons per day average during the winter and
200,000 gallons per day during the summer season. The annual maximum one-
oay usage ranged from 557,000 gallons in 1984 to 663,000 gallons in 1987,
and have been projected to be 858,000 gallons by the year 2010, provided
that development continues at its present rate.
During 1988, Buck and Buck Engineers of Hartford, CT prepared a
report on the water supply system which suggested that without
augmentation by water supply wells, the reservoir supply would not provide
an adequate quantity of water during drought conditions if they were
similar to the 1960's drought (100 yr frequency). They further concluded
that if the water supply was augmented by pumping 250,000 GPD into Middle
F~rms ?ond Juring August, September and October, storage would be
marginal. They finally concluded that if the surface supply was fully
augmented by the Middle Farms well field, there would be an adequate
supply of water during a 1960's type drought.
An alternate groundwater supply of 200,000 gallons per day
groundwater was recommended and subsequently implemented.
The groundwater quality has been good with the exception of high iron
concentrations which has ranged from 0.1 to 13.7 mg/l (Ref. Appendix of
Report on Fishers Island Water Works, Buck and Buck Engineers, Hartford,
Conn. Jan. 29, 1988). As previously mentioned, chemicals are used to
sequester the iron in the distribution system. However, this method is

suitable only for concentrations up to I mg/l. Iron concentrations in
excess of 0.3 mg/l are unsatisfactory. If manganese is present, the
allowable total of iron and manganese is 0.5 mg/l.
Water Budqet
This section of the report addresses the overall water budget for the
Fishers Island Water Works Corporation; and the study area.
Barlow Pond, Middle Farms Pond, Treasure Pond and the currently
active Middle Farms Flats well field are considered potential sources of
water supply in the event of drought conditions. Therefore, the overall
water balance will consider all of these water supplies.
The water budgot can be described algebraically as follows:
WS = DP + SR + I - E - ET - Consumption
Where WS is Water Surplus
DP is Direct Precipitation
BE .~ Surface Run-off
I is Infiltration into the Well Field Cone of Depression
E = Evaporation from Pond Surfaces
ET = Evapotranspiration from Grassed, Brushy or Wooded
Tributary Areas
C = Consumption including Unaccounted for Water
Direct precipitation averages 53 inches (4.42 feet) per year on
Fishers Island based upon data presented in the Groundwater, Inc. report
of April, 1990. Surface run-off for the sandy soils and extremely brushy
3-3
watershed based upon review of the above mentioned report is about 15\.
Mdny rain events were observed during the field work, however run-off was
observed only at the low points of the roadways. No rive1ets or temporary
streams, other than roadway run-off, were observed. Therefore we believe
the surface runoff is about ten (10) percent and have used ten (10)
percent in the water budget.
Infiltration or recharge of the groundwater table within KiddIe Farms
Flats aquifer is estimated to be 90\ of the precipitation which does not
transpire or evaporate.
Evaporation on Fishers Island ranges from 12 inches to 17 inches per
year according to the aforementioned report, and transpiration is about 9
inches per year.
The projected annual consumption rate estimated by the Fishers Island
Wal~r WOLk~, Inc. is 87 million gallons for the year 2015. This data was
tai;en from "Report on Fishers Island Water Works", dated January 29, 1988,
by Buck i B~ck Engineers of Hartford, Connecticut.
The aLeas of the reservoirs and watersheds are listed in Table 3-1.

In summary, during a prolonged drought period, the total surface

The Well Field alone cannot supply enough water during drought
periods even if induced infiltration takes place. The worst case
would be without induced infiltration during a drought for the demand
of the year 2015. The well field would supply 28.8 million gallons
of water and the annual consumption would be 87 million gallons or a
deficit of 58.2 million gallons would occur.
It can be concluded that the surface water treatment plant must
remain on stand-by.

CHAPTER FOUR
RESERVOIR WATER QUALITY SAMPLING AND ANALYSES
Introduction
Barlow Pond, Middle Farms Pond and Treasure Pond were sampled during
September 16, 1992 (after a period without rainfall), and September 24,
1992 (after rainfall). The sample locations are shown on Figure 5-1.
The samples were obtained at the centers of the ponds as shown on
Figure 5-1 and were taken from mid-depth, based upon the assumption that
the ponds are shallow and complete mixing of the water occurs.
The depths at the centers of Barlow Pond, Middle Farms Pond and
Treasure Pond were found to be 24 feet, 21 feet and 12 feet respectively.
(The ponds are deeper than previously assumed.)
Samples were obtained at mid-depth utilizing 1/2 gallon sampling
equipment and weights. The samples were analyzed for physical
constituents temperature, color, odor, pH, turbidity, sediment,
conductivity, and total solids. Chemical constituents sampled were
nitrogen, chloride, alkalinity, hardness, Free CO2, iron, manganese,
phosphate, and sodium. Bacteriological analyses included total coli forms,
fecal coliform and fecal streptococcus.
Description
The color of Barlow Pond was six times the allowable limit of 15
units at 90 units, Middle Farms Pond was 20 units and Treasure Pond was 5
units. Total solids were in the range of 70 mgll for all three ponds.
Nitrogen for all three water bodies was typical for small northeastern
r~servoirs with low density developed watersheds on both sampling
occasions.

Chlorides were in a similar range for all three ponds. The chloride
content of about 30 mg/l is relatively high for surface waters in rural
areas as was the specific conductance. However, the proximity of the pond
to the ocean and the associated aerosol transportation of chlorides most
probably accounts for the anomaly. The alkalinity of the three ponds was
low and the waters may be classified as soft or very soft. The iron
content of Barlow Pond is high at 0.84 ppm (the maximum for potable water
is 0.3 mg/l) whereas Middle Farms Pond was lower at 0.16 ppm and Treasure
Pond was very low at less than 0.01 mg/l. The existence of high iron
concentrations in Barlow Pond are, according to the Suffolk County
Department of Health Services, Bureau of Drinking Water, relatively well
understood. The iron is thought to result from the long practice of
disposing of waste backwash water from the filters at the surface water
filtration plant directly into the pond. There originally were provisions
for clarification of the backwash water which would allow iron to settle
out. The Bureau of Drinking Water believes the backwash water clarifier
has not been used in many years due to a broken line.
Several samples revealed bacterial content. The Barlow Pond sample
indicated 5, 2 and 3 per 100 ml for total coliforms, fecal coliforms and
fecal streptococcus respectively during the 9/17/92 sample and 20, 18 and
: per 100 ml for the 9/24 sample. The first set of Middle Farms Pond
samples revealed concentrations of 23, 0 and 0 per 100 ml for the total,
fecal, and streptococcus and 260, 680 and 0 per 100 ml respectively for
the second set of samples. Middle Farms Pond should be resampled for
bacteria, especially near residences to verify the results.
The results of the reservoir raw water quality sampling and analyses
indicate that the raw water quality is typical of small northeastern
surface supplies with low density developed watersheds. The sampling
program confirmed the need for filtration of the surface waters.
Laboratory data is included in Appendix A at the end of this report.

CHAPTER FIVE
TEST BORINGS AND MONITORING WELL PROGRAM
A. Introduction
A test well and monitoring well program was conducted within the
study area during September 1992, by ARL, Inc. Clarence Welti Associates,
Inc. provided subcontract services including the actual borings and
monitoring well installations, soil sampling and boring log preparation.
The soil samples obtained are split spoon samples which were obtained at
10 foot intervals. Samples were observed, logged and placed in sample
jars. The eleven monitoring wells and a single boring is shown on Figure
5-1 at the back of this report and the Boring Logs are in Appendix C.
The purpose of the monitoring well program was to determine 1) the
character of the soils, 2) the groundwater surface elevations and
gradients and 3) analyze the groundwater quality.
The selection of the monitoring well locations was based upon
sections and data in the island-wide hydrogeologic report published April
1990, by Ground Water, Inc., and existing and potential future sources of
pullution as discussed in Chapter 8.
B. Soils Characteristics
The general surficial geology within the study area is shown in
Figure 5-2. Based upon this U.S.G.S. surficial geology mapping, end-
moraine deposits ring Barlow Pond, Middle Farms Pond and Treasure Pond.
End-moraine deposits are defined as a complex assemblage of well-sorted
sand, gravel and till. It includes small glacial kettle fillings of silt
and fine sand, which occurs only on Fishers Island. The area immediately
southwest of Barlow Pond and in Middle Farms flats is defined as Qsg which
is d~scribed by U.S.G,S. as "sand plain deposits" which are sand and minor

gravel underlying "sand plains" 10 to 20 feet above sea level on Fishers
Island.
Based upon the boring logs for monitoring well .1 and monitoring well
~2, at least a 21 feet thick light brown fine to medium sand surficial
deposit exists in the area southwest of Barlow Pond. The extent of this
sand in the direction of Barlow Pond is greater than shown by the U.S.C.S.,
see Figure 5-2. The depth of this sandy material is greater than
previously estimated, based upon the borings and visual observation of a
large abandoned well field which is in the area southwest of Barlow Pond
and north of Brickyard Pond.
The boring logs and observations of soils for monitoring well 13
northwest of the pond reveal some silt from 20.0' to 21.5'. The estimated
permeability of this soil is less than 2 ft/day. This soil forms a dike
which contains the water in Barlow Pond. The soil is consistent with the
Figure 5-2, and the U.S.C.S. description, i.e., it appears to be an end-
moraine deposit.
The boring logs for monitoring well '4 which is located north of
Barlow Pond near Mrs. Cordon Murphy's residence, indicate that a light
brown coarse to fine sand, some fine to coarse gravel, a few cobbles and
boulders exist. Some of the cuttings contained more silt than the boring
logs indicate. Therefore, it is our opinion that the logs are consistent
with the Qem, end-moraine deposits shown on Figure 5-2 and the
permeability is relatively low.
The boring logs and soils observations for monitoring well '5 near
the water treatment plant indicate that the soils are light brown fine to
medium sand, with a trace of silt. The appearance, grain size and
gradation is consistent with the Qsg or sand plain deposits, not the end-
moraine deposits which were identified by the U.S.C.S. and are shown in
Figure 5-2.
The permeability of the soil found in monitoring well .5 is estimated
to be about 10 to 25 feet per day. It can be concluded that the
5-3
relatively narrow soil berm between Barlow Pond and Island Pond which is
about 4 feet lower, offers little resistance to flow from Barlow Pond to
Island Pond. It is likely that sediment at the bottom of Barlow Pond
provides the most significant barrier to groundwater flow from Barlow Pond
to Island Pond.
During the reservoir sampling program, it was noted that Barlow
Pond, Middle Farms Pond and Treasure Pond have significant deposits of
muck on their bottoms.
Monitoring well '6 was placed near the driveway entrance to
Bagley Ried's residence at the south end of Barlow Pond. The soil to a
depth of 18.0 feet is light brown fine to medium sand, with a trace of
silt. The soils between 18 feet and 25 feet is coarse to medium sand
which indicated that the boring was within the sand plain deposit.
The material at the bottom of the boring appeared to be excellent
wdLer yielding material and the location with respect to the water
distribution system is such that a new water supply well could be
developed and connected to the existing water distribution system.
After discussions with Mr. Robert Wall and evaluation of the
monitoring well #6 boring logs, it was decided to be worthwhile to bore a
hole (B-1) about 12 feet from the monitoring well '6 and explore the
possibility of a new water supply well. The boring log and observations
indicate that the soil is not sufficiently permeable for a high yield
water supply well.
Monitoring well '7 located south of Middle Farms Pond near the Miller
residence resulted in light brown fine to medium sand with a trace of silt
which indicates it is part of the sand plain deposits. The water table
was relatively shallow. The permeability is estimated to be 10 to 50 feet
per day.

determine the characteristics of deep underlying soils and to sample
selected contaminants such as sodium and chlorides because the fresh water
aquifer is near and possibly over brackish to saline water.
The upper 18.0 foot layer of soil was light brown fine to medium
sand. The 18.0 foot to 35 foot layer is light brown fine to medium sand
with a trace of coarse sand. The soil from 35 feet to 45 feet was
similar. A thin sand, silt and clay lense exists between 45.0 feet and 55
feet. Fine to coarse sand exists to 96 feet. The soil from 96.0 feet to
151.5 feet consists of compact grey silt, fine sand and clay. In summary,
the material down to 96 feet is relatively permeable. Below that
elevation, the soils are impermeable.
Based on the monitoring well .8 log, it can be concluded that the
d~uifer is much deeper near Middle Farms Pond than previously thought and
reported, and the aquifer top and end are not confined near the Middle
Farms Pond. It is probable that Middle Farms Pond is within the cone of
Jepression and supplies water to the well field via induced infiltration.
The monitoring well '9 is located near the main road north of the
Laughlin residence driveway and Middle Farms Pond. The boring revealed a
silty soil which most likely can be characterized by low permeabilities
near th~ surface and at the ground water surface elevation, and higher
permeabilities at deeper (13.0-21.5') depths. This soil is relatively
consistent with the end-moraine deposit description. It can be concluded
that floating pollotants would most likely travel slowly in this soil.
The monitoring well '10 is located adjacent to the main road north of
the Rafferty residence and Middle Farms Pond. The soils characteristics
based upon the field observations, samples and boring logs can be
characterized as light brown fine sand, little silt, cobbles and boulders.
This soil has relatively low permeabilities and fits the description of
end-moraine deposits.
The boring and monitoring well .11 are located west of Middle Farms
Pond and the Templeton residence. These soils, based upon the field
5-5
observations and boring logs are light brown fine to medium sand underlain
by light brown fine to coarse sand, and little fine to coarse gravel.
The soils at monitoring well III are relatively permeable near the
groundwater surface. The estimated permeability of the upper 96 feet
generally is in the 50 ft/day to 100 ft/day range. Some layers of less
permeable soils are within this upper layer. However, the aquifer is not
confined. Therefore, it is possible that surface pollutants including any
oil, gasoline, nitrates, fertilizers, pesticides or herbicides could move
downward and be captured by the water supply system cone of depression.
C. Hydraulic Gradients
One purpose of the monitoring well program was determination of
hydraulic gradients around Barlow, Middle Farms and Treasure Ponds.
The direction and gradient of the groundwater surfaces around
the ponds determines the destination and velocities of pollutants within
the aquifer.

In order to determine the gradients of the water surfaces around the
three ponds, the elevations of the ponds were surveyed utilizing
verifiable benchmarks and determined to be as follows:

The water elevations within the monitoring wells were then determined
and the estimated distances from the monitor ing wells to the water bodies
were scaled fr om the map.
The resulting data is shown in Table 5-2.
It can be concluded that the flow of groundwater was away from
the ponds in all cases, and the surface gradients vary from 0.0010 ft/ft
to 0.0454 feet/feet.
D. Groundwater Samolino and Analvses
This section describes the purposes, procedures and results of the
groundwater sampling program.
'It should be noted that actual water elevations vary significantly from
the values shown on the Fishers Island topographic mapping that was
utilized as part of this study.

The monitoring wells are located based upon soils evaluations, water
level evaluations and water quality evaluations.
All of the monitoring wells are shown on Figure 5-1. Certain wells
were selected for sampling based upon the premise that they were located
where potential plumes from residential sites exist. Monitoring wells 4,
5, 6, 7, 9, 10 and 11 were placed down gradient from r!sidences and the
water treatment plant and were tested for volatile organic compounds
(502.2), pesticides and selected sanitary contaminants. Monitoring well
#8 which is 150 feet deep was sampled for selected constituents such as
chlorides to determine if salt water intrusion has occurred. A summary of
the monitoring wells which were sampled and the contaminants sampled are
shown in Table 5-3 and the results of the analyses are shown in Appendix
D.

Monitorina Well .1 is located near the road southwest of Barlow Pond.
The screen is set to recover constituents near the groundwater surface.
No VOC's were found to be in the water. Iron and manganese were found to
be elevated but not excessive at 0.41 mg/l and 0.17 mg/l respectively.
The field pH was law at 5.7
Monitorinq Well .2 is located southwest of Barlow Pond near three (3)
residences. The hydraulic gradient was sloped downward from Barlow Pond
toward the residences during the sampling program. Therefore, it is
unlikely that residential sources of pollution impacted this well at the
time. A reversal of the gradient toward Barlow Pond during dry weather
could result in future elevated parameters in this well from the
residences and nearby abandoned well field equipment. The well screen is
set to obtain samples near the groundwater surface.
No VOC's, herbicides or pesticides were found. The albuminoid
nitrogen was at 0.48 mg/l indicating most likely decaying vegetation. All
other constituents were low, indicating good quality water. The field pH
was low at 5.2.
Monitorina Well #3 was not sampled because it was installed to
determine soils and groundwater characteristics only.
Monitorinq Well '4 was located north of Barlow Pond near the road and
near three (3) residences. Evaluation of the groundwater surface gradient
indicates that the groundwater most likely was flowing away from Barlow
Pond at the time the samples were obtained. The screen is set to obtain
samples near the surface of the groundwater table.
VOC's, herbicides and pesticides were not found. Manganese was
elevated at 0.63 mg/l and nitrates were above background levels indicating
some probable human impact on the groundwater quality. The field pH was
low at 5.7.
Monitorinq Well '5 is located near the water treatment plant. The
screen was set to obtain samples from near the groundwater surface. The
5-13
gradient was from Barlow Pond toward Island Pond. No VOC's were found to
be present in this groundwater. The albuminoid nitrogen was 0.48 mg/l
which may be from decayed matter at the bottom of Barlow Pond. The
conductivity at 190 indicated elevated mineral content compared with other
samples. Nitrate nitrogen was elevated at 2.06 mg/l. This elevated
nitrate cannot be explained at this time. The pH was 6.5 which most
likely indicates the influence of Barlow Pond water.
MonitorinQ Well 16 was located southwest of Barlow Pond near the
Bagley Reid residence. The gradient of the groundwater surface indicates
that the flow was southwest from Barlow Pond under the residence. No
VOC's, herbicides or pesticides were found. Only manganese was found to
be elevated at 0.36 mg/l.
MonitorinQ Well 17 was located south of Middle Farms Pond and several
residences. The gradient of the groundwater indicates that the flow was
most likely from under at least one residence. It is possible, based upon
review of the topography, that groundwater flows from under several of
these residences. No VOC's, pesticides or herbicides were found.
Albuminoid nitrogen content was high at 0.96 mg/l which may be the result
of human activities or natural decay of vegetation. Nitrate nitrogen was
elevated above background levels at 1.18 mg/l indicating possible
fertilizer or septic system influence.
MonitorinQ Well 18 is a 150 feet deep well west of Middle Farms Pond.
The purpooe of this well was the determination of soils characteristics
and potential chloride intrusion at deep depths. The chloride content was
elevated at 30 mg/l which is not extremely high for this area. Monitoring
well 20 which was installed about 600 feet south of MW 8 had 91 mg/l
chlorides during the 11/14/88 sample period which indicates potential
southern saltwater intrusions from Block Island Sound. Chlorides can also
be transported from sea water onto land as aerosols. Therefore, 30 mg/l
of chloride concentration does not seem excessive. However, in view of
the relatively low chloride concentration at 150 feet deep in MW 18, the
concentration of 91 mg/l in MW 20 which is about 80 feet deep does seem
excessive and should be monitored very carefully and frequently.

Monitorinq Well '9 was not sampled.
Monitorino Well .10 is located near the main road north of Middle
Farms Pond. The groundwater gradient indicates that water flows from Middle
Farms Pond toward Fishers Island Pond and most likely flows under a
residence.
The conductivity at 220 micromhos, the manganese at 1.3 mg/l, the
nitrate nitrogen at 12.4 mg/l, the pH at 7.1 and the sodium at 26.0 mg/l
all indicate that a source or sources of groundwater pollution are nearby.
The nitrate level exceeds the allowable limit for drinking water. VOC's
were not found.
Monitorinq Well #11 is located west of Middle Farms Pond. Based upon
the gradient of the groundwater surface, the groundwater flows from Middle
Farms Pond toward the well field. The groundwater most likely flows from
under one residence.
The screen is set at a level which will capture pollutants on or near
the surface of the groundwater. This well is an important indicator of
potential pollution of the well field. It should be monitored in addition
to MW #8 in the future.
No VOC's, herbicides or pesticides were found.

CHAPTER SIX
THE BARLOW POND INFILTRATION GALLERY/UNDERDRAIN
A. Introduction
This section of the report addresses the location of the underdrain
which extends from the main road at a point about 3,000 feet southwest of
Barlow Pond to the pond. The physical description of the drain, the
tributary area, the history, flow evaluations, and potential pollution are
discussed in the following narrative.
B. Descriotion
The underdrain or "Infiltration Gallery" was evaluated initially by
ARL, Inc. utilizing the old 1931 plans by W. Brown, Inc. which were
supplied to us by Mr. Robert Wall, Superintendent of the Fishers Island
Water Works, Inc. The horizontal alignment of the infiltration gallery is
clearly shown on this plan. Our reproduction of this conduit alignment is
shown on the map identified as Figure 6-1 (at the back of the report).
The total length is 3,800 feet. The upstream end of the gallery system
begins with a series of ditches which collect run-off from the Isabella
Bluff area. Based on the old plans, these drainage ditches were very
extensive. Substantial flows were observed in these ditches by ARL staff
during April, 1992. The overland flow enters head walls and a closed
conduit south of the main road 150 feet west of Pole 1773. It then flows
south within what is thought to be a 12" diameter tile conduit to the edge
of the swamp behind Chip Dupont's house. It should be noted that no swamp
existed in 1931. Two major drainage ditches crossed this land which is
now a swamp and exited at the two drainage culverts shown on Figure 6-1.
The drain turns northward at this point and parallels the swamp under a
man-made berm. At about 200 feet along the way, a 12" diameter outfall
juts out toward the swamp at an elevation of 3 feet above the swamp water
level. This outfall was dry when it was observed during the Spring of
1992, but was submerged during an inspection in March of 1993.
6-1
The drain zig-zags about 500 feet northeast across the DuPont land to
an un-named road. It then turns about 20 degrees in an easterly direction
and extends about 400 feet to Grey Gull Lane. It then turns northward and
extends about 1,700 feet to the intersection of the Barlow Pond Roadway.
From this point, it extends about 300 feet to a point that extends
approximately 25 feet into Barlow Pond.
The pipe is tile, based upon the field observations, discussions with
Mr. Cavanaugh (who has indicated that he worked on the construction of it)
and the physical tracing of the pipe into Barlow Pond. The outfall pipe
was buried and could not be seen. However, the tile pipe bells could be
felt through the bottoms of the waders. The outfall pipe size in Barlow
Pond is most likely 15 inches diameter.
Manholes 1, 2, 5 on the map shown in Figure 6-1, and two more near
the swamp behind the DuPont house were found and inspected. They are 5
foot diameter brick and mortar manholes.
The mortar of Manhole .5 was broken to the point that overland flow
was seeping into it at a rapid rate of flow during early spring. In
general, the manholes appear to be in good condition with the exception of
manhole #5, which should be repaired.
Manhole 12 probably has a valve in it just below the water level
because the top square turning bar was only visible. The pipe and manhole
bottoms were impossible to inspect because the waters are murky.
Turbidity, and color from lignins and tannins appear to be present in the
water and visibility is extremely limited. It is therefore recommended
that the inlets and outlets be temporarily plugged, and the manholes
should be pumped and examined.
C. Tributary Area
The total infiltration gallery tributary surface area is about 127
acres as compared with Barlow Pond's 31 acre tributary area. The surface
tributary area extends southward to within 300 feet of the Pickett

Landfill. About 92 acres of land between the main road and the Isabella
Bluffs contribute surface water to the drainage ditches near Pole 1773 and
the culvert near Grey Gull Lane.
The subsurface tributary area is extremely difficult to estimate.
The majority of the drain lies in sandy soils. The pipe invert or bottom
is about 4 feet below the groundwater table and about 10 feet below grade
in the manholes which were inspected. The Manholes 1, 2 and 5 which were
found and inspected are near Barlow Pond and Grey Gull Lane. The width of
the zone of influence of this drain, in the event it was flowing toward
Barlow Pond, would be substantial (Barlow Pond must be drained down for
this to occur.). Assuming the zone of influence of the drain averages 300
feet wide when Barlow Pond is drained and water flows through the drain
tuwdrds il, the tolal groundwater tributary area to the drain is about 26
acres. The width of groundwater influence most likely varies greatly
depending upon the depth of the drain and the types of soils (sands, tills
and muck).
History
The 1931 plans by W. C. Brown, Inc. describe the drain as an
":nfillration Gallery". Based upon this description and the drain
configuration (see Figure 6-1), it is probable that the drain has been
used to supplement Barlow Pond water during drought periods. Our
invesligations show that various means including pumping water from Middle
Farms Pond have been used to augment the Barlow Pond water supply during
droughts and/or high summer usage periods.
It has been suggested that during the early 1920's, the upper reaches
of this drain were constructed for the purposes of dewatering the
abandoned clay pits for clay mining and brick making. This line could
have extended to and terminated at the outfall into the DuPont swamp
because early maps show a drainage ditch from the 12-inch outfall directly
lo Fishers Island Sound, and another drainage ditch is located on the east
side of Dupont's land and drains to Fishers Island Sound.
6-3
Another key piece of evidence that the drain was extended to augment
the Barlow Pond water supply is the fact that an abandoned well field lies
immediately south of the pond. The well field had numerous well points,
an elaborate suction manifold, a huge gasoline driven pump and a raw
water main extending toward Barlow Pond. It was most likely used to
supplement the Barlow Pond water supply. Therefore, we conclude the need
for Barlow Pond augmentation existed during early years.
Flow Evaluations
No movement of the existing water was noted during numerous
inspections of manholes 1, 2 and 5. Substantial overland flow from the
northwest slopes of the Isabella Bluffs has been observed entering the
head walls of the conduit near the main road and Pole '773, and
substantial flows have been seen entering the cracked mortar of Manhole '5
near Grey Gull Lane. This manhole is within the drainage ditch which
extends to the main road and a 10" diameter culvert under the main road
which in turn drains the surface water from the Isabella Bluff area.
Also the land depressions
during the less rainy periods.
DuPont swamp outfall.
on both sides of Grey Gull Lane drain
No outflow has been observed at the 12"
Dye tracing of flow between Manhole '1 and Manhole '2 near Barlow
Pond has substantiated that after rainfall events water flows from Barlow
Pond toward Grey Gull Lane.
It can be hypothesized that during rainstorms, the Barlow Pond water
elevation rises quickly, reflecting the amount of precipitation (Bob Wall,
the Fishers Island Water Works Supervisor, indicated that when it rains
I", the Pond raises 1"1. The sandy aquifer which surrounds the drain
rises more slowly and therefore forms a sink to accept flow, and results
in flow away from Barlow Pond.
During drought conditions, the flow would be reversed toward
Barlow Pond, and the infiltration gallery would provide added water supply

to Barlow Pond. The drain and surrounding aquifer provide additional
water storage. The reversal of flow would result in transport of
pollutants from the drain tributary to the pond.
F. Potential Pollution
The sources of pollution within the tributary area are relatively
well defined but dispersed. They are non-point sources from four
residences, roadway run-off from the main road and some potential
fertilized areas. Non-point sources of pollution also include water fowl
and animal wastes. The possibility of an oil tank leak, an oil spill on
the main road or gasoline leakage into the surface water or aquifer
exists. Any and all chemicals applied to the ground within the tributary
area could eventually end up in Barlow Pond.
A possible but not probable source of pollution is the Pickett
Landfill because the sand plain soils extend from the area of the landfill
to Barlow Pond. However, the pollutant would have to move 1,900 feet in
the groundwater table. The most likely source of pollutants with
potential impact on Barlow Pond are the potential sources identified at
the three residences adjacent to the infiltration gallery and the Pond.
In the event that any homes are proposed near Barlow Pond, potential
pollutant sources, direct pathways (overland and through the groundwater)
and indirect pathways (through the drain) will have to be evaluated.
The next most direct pathway for pollutants to enter the Barlow Pond
via the drain is overland drainage from the abandoned clay pit to the main
road, under the main road via the 10" diameter culvert and into Manhole '8
near Grey Gull Lane or via septic systems constructed near the underdrain.
Finally, it has been indicated that the potential for hydrocarbon
contamination of the abandoned well field exists because gasoline, grease
and other materials were used within the aquifer area. The destination of
these pollutants could be Barlow Pond via the drain.

In summary, the underdrain is 3,800 feet long and drains an area that
extends an additional 1,400 feet further from Barlow Pond. The surface
tributary area of the underdrain is 3.5 times as large as the Barlow Pond
watershed area or 127 acres. The groundwater tributary area to the drain
is estimated to be 26 acres which is 2/3's the size of Barlow Pond's
tributary area. The history of the construction of the drain dates to
before 1929 and, most likely, the post World I era. Flow character-
istics in the drain have not been completely defined, and the risk of
pollution of the drain is low to moderate except from septic systems in
the vicinity of Barlow Pond. The risk of pollution of Barlow Pond via the
underdrain would increase substantially during drought conditions when the
pond must be drawn down or excessive evaporation occurs.
A drought or drawdown of Barlow Pond would greatly increase the
likelihood of pollution of the pond via the infiltration gallery.

CHAPTER SEVEN
HYDROGEOLOGIC SECTION
A. Introduction
The purpose of plotting a hydrogeologic cross section in the study
area, which includes the three (3) ponds and the Middle Farms aquifer, is
to assess the potential of surface and groundwater pollution by
contaminants which enter the aquifer.
B. Description
During September 1992, ARL, Inc. determined the groundwater and
surface water elevations of eleven (11) monitoring wells and three (3)
ponds. Based upon the results, we conclude the groundwater normally flows
away from Barlow Pond in all directions, and away from Middle Farms Pond
in the southerly, westerly and northerly directions. Based upon
previously published data, Treasure Pond groundwater most probably flows
south and west. Middle Farms Pond and Treasure Pond may recharge from the
east and north respectively, again based upon the April 1990 Groundwater,
Inc. report.
Specifically, the normal groundwater direction of flow moves existing
pollutants away from the surface waters. Two phenomena can reverse these
flow directions at Barlow Pond. The first is a drought similar to those
occurring during July 1929 through December 1932, September 1940 through
April 1945 and August 1961 through November 1971 which lower the levels of
the ponds and reverse the groundwater flow. It is possible, but has not
been substantiated herein, that other periods of drawdown of Barlow Pond
have occurred in the past. The second phenomena is reversal of pathways
of groundwater flow and pollutants caused by dense, fine grained layers of
soils in some areas near the ponds.
7-1
Soils logs from test holes for a septic system which were excavated in
the southeast portion of the Barlow Pond watershed revealed a sandy till
soil with mottling at 10 feet below grade. Grade is at elevation 25 feet
msl. The mottling indicates the seasonal water table elevation and that a
restrictive layer of soil exists at about elevation 15 feet msl. This
test hole was about 210 feet from Barlow Pond which has a surface
elevation of about 6.0 msl. The hydraulic gradient could be 0.0429 ft/ft
during the high groundwater period. The water table based upon the test
hole mottling was much higher than Barlow Pond and groundwater most likely
drains toward the pond. It is unlikely but possible that bacteria could
reach the pond from this septic system. Nutrients and trace organics most
likely presently flow to the pond within the groundwater flow.
Direct pollution of the Middle Farm Flats groundwater is possible
because the aquifer is unconfined and the cones of depression of the water
supply wells are large. In addition to direct pollution, it is possible
that polluted run-off from the area north of the well field could flow
overland to the well field and infiltrate into the aquifer.
The geologic units of the area are shown in Figure 7-1. Large areas
of proximal or fine to medium sand, Qsq, are present southwest of Barlow
Pond and within Middle Farms Flats. The depth of this sand is greater
than 22 feet in the area of MW 12 and greater than 38 feet at MW '5.
Interestingly, MW G5 previously installed indicated the sand layer to be
about 13 feet thick at a location just 200 feet from MW '2. The thickness
of the proximal outwash varies greatly in the Middle Farms Flats area. At
HW 18, it is about 100 feet deep and at MW 20 it is shown as 8 feet deep
in the GWI report.
The cross section west to east across the SIMA, Church and "Hers"
production wells is shown as a 70 foot to 30 foot thick band of sand and
gravel overlain by silt and fine sand. The sand and gravel bows down to
70 feet below grade. ARL, Inc. found that, based upon MW '8 logs, the
sand extends from the surface to 96 feet below grade at the eastern edge
of the aquifer near Middle Farms Pond. Therefore, according to the boring
data, it may be concluded that the aquifer thickens as it extends from the

well field a~ea to Middle Fa~ms Pond and it is not confined. It is
probable that water flows f~om Middle Fa~ms Pond into the well field.
Figure 7-2 shows the c~oss-section line on a topog~aphic map.
Monitoring wells '2, 5, MW2D and 8 a~e shown on this map because they
were used to dete~mine c~oss section cha~acteristics.
In orde~ to illust~ate the effect of d~oughts or drawdown on the
pathways of pollutants, and to illustrate gene~al water table
characteristics of the study area Figures 7-3 and 7-4 are presented.
Figure 7-3 shows the cross section of conditions which existed
during September 1992 when the ARL survey crew measured the water surface
elevations. The cone of depression for the well field is generalized
based upon published information and data. The pathways of pollutants
within the groundwater are away f~om Barlow Pond and the west end of
Middle Farms Pond.
Figure 7-4 shows a condition which could exist during a d~ought.
Barlow Pond's water elevation was 1.5 feet msl du~ing the 1960 drought.
During the drought period the gradient ~everses. This condition would be
worse in the southwest and northern edges of Barlow Pond. As previously
fil~ntioned, the result would be t~avel of pollutants from the surrounding
areas toward the ponds. The infiltration gallery flow would also reverse.

CHAPTER EIGHT
DETERMINATION OF POTENTIAL CONTAMINANT SOURCES
A. Introduction
This Chapter describes the methods used to identify, assess and map
the potential sources of ground and surface water pollution within the
water supply watershed area. The potential sources include residential
development, roadways, the water treatment plant, the golf range and salt
water bodies. Sources can be categorized as point and non-point
(dispersed sources). Identified potential sources are shown on the map,
Figure 5-1 at the back of this report.
B. Description of Contaminant Types
The potential sources of pollution identified within the study area
include lhe following point sources:
Residential septic systems
Oil storage tanks
Swimming pool discharges
Non-point sources include:
Herbicides and pesticides used
Fertilizers used for lawns and
Roadway runoff
Salt water intrusion
for lawns, shrubs and gardens
shrubbery
Construction erosion
Animal manure
Water fowl
of ground and surface
and sedimentation
waters
8-1
1. Point Sources
a. Residential On Site Disposal Systems
Many of the existing on site wastewater disposal systems in
the planning area are old and most likely substandard. Some maybe
leaching cesspools and lack septic tanks. All on site disposal systems
are sources of bacteria, viruses, nitrogen, phosphorous, trace organics,
and other pollutants.
(1) Bacteria including fecal coliform and fecal
streptococcus from human waste discharges can travel
long distances in saturated, porous soils. The
inclusion of clay lenses in the soils which occurs on
Fishers Island within the study area can restrict
downward movement of septic system effluent and result
in horizontal movement of septic system effluent
toward surface waters. Bacteria survive in aqueous
solutions for extended periods of time. Some authors
have cited a survival time in the groundwaters of New
England of three (3) to six (6) weeks as a reasonable
figure.
(2) Virus tend to conform with the same principals applied
to bacterial for survival in on site disposal systems,
with one distinct and important difference. Viral
organisms can survive for extended periods of time in
saturated soils and will therefore travel great
distances [if they survive) to reach the groundwater
level. The critical safeguard is maintenance of ~
adecuate depth of unsaturated soil between a leaching
system with a viable biological growth layer and the
groundwater table. Most research in the laboratory
and field indicates sixty [60) cm (2 feet) of
unsaturated porous soil can remove viruses very
effectively.

Overland flow of wastewater from failed septic systems
that are underlain with marginal soil conditions could
result in direct pollution of the receiving waters
with both bacteria and viruses.
(3) Nitroqen, N in the form of nitrate ion (N03 ) is
considered a pollutant if it exceeds the concentration
of greater than 10 mg/l as N according to the U.S.
Public Health Service. The nitrate has been known to
cause an infant disease known as Methemoglobinemia.
The sources of nitrogen in the study area include
septic systems, lawn fertilizers, and animal wastes.
Nitrogen discharges to surface waters promotes aquatic
weed growth, "duck" weeds, algae, and macrophytes.
Nitrogen is a necessary element for aquatic weed
growth, but may not be the limiting nutrient for the
Island ponds. It is most likely that phosphorus is
the limiting nutrient.
During the reservoir sampling program, abundant
growths of aquatic plants, especially macrophytes,
were observed in all reservoirs, especially Treasure
Pond.
(4) Phosphorus
Septic systems discharge relatively large amounts of
phosphorus. The phosphorus is bound to the underlying
soils depending upon the cation exchange capacity of
the soil. In general, sandy soils absorb less
phosphorus than silts and clays. In general, the
larger the soil particle size, the lower the capacity
of the soil to absorb phosphorus. The sandy soils
adjacent to the ponds and in the aquifer are most
likely relatively poor absorbers of phosphorus.
8-3
(5) Trace Organic Chemicals are sometime present in
household wastewater. The sources of trace organics
can be cleaners, solvents, degreasers, paint products,
antifreeze, motor oils, furniture strippers,
photographic chemicals and other household chemicals.
Some septic system additives contain organic chemicals
which enter and pollute groundwaters.
In addition to groundwater pollution, failed septic
systems within the watershed could result in overland
flow and water pollution with trace organics.
Normally, some trace organics will be removed in the
soils by volatilization, chemical reactions, and
absorption.
b. Heatinq Oil Storaqe Tanks
Heating oil storage tanks, especially underground tanks can
rust and leak causing contamination of soils and the groundwater. Host of
the residences and the water treatment plant have oil storage tanks on
their sites. The primary constituent of concern is the carcinogen
benzene. Residences which have oil storage tanks on their premises are
shown on Tables 8-1 through 8-4 on the following pages.
c. Swimminq Pool Wastes
The potential pollutants associated with swimming pool
backwash include bacteria such as fecal coliforms and fecal streptococcus,
chlorine (HTHl, stabilizing acids such as cyanatic acid, algae, alkalinity
additives and diatomaceous earth. In some cases, pool water is held for
long periods of time, which can result in pollutant concentration.

2. Non-Point Sources
a. Pesticides and Herbicides
Pesticides and herbicides that are used for lawns, orchards
and shrubs can be dangerous to human health if consumed in drinking water.
Extensive pesticide and herbicide constituents are now required for
monitoring under the Safe Drinking Water Act. The current EPA Phase II
and Phase V requirements and the New York Sanitary Code monitoring
requirements are more stringent that the sampling regime defined in the
scope of this study. However, the lack of pesticides and herbicides in
the sam~]es analyzed for this study is most probably indicative of
prese~C2 or absence of other contaminants.
b. Fertilizers
Fertilizers contain nitrogen and phosphorus which nourish
aquatic plant life. The plants flourish, die, settle to the bottoms of the
rescrvuirs arId decay causing oxygen uptake, and taste and odor in the
drinking water.
The proximity of some lawns, and shrubs to the surface
water reservoirs most likely results in increased nutrient loadings.
During rainstorms, the fertilizers are washed into the three (3) ponds,
and eventually seep into the Middle Farms Flats Aquifer.
c. Roadway Run-Off
Roadway run-off can include BOD, nitrogen, sodium,
chlorides, phosphorus, grease, petroleum, chromium, lead, zinc and copper.
Fuel oil and gasoline spills are probable. The benzene
content of the fuel, and the pathways that these pollutants follow, are
the most critical concerns.
8-5
The loading of pollutants on a receiving water from roadway
run-off depends upon the volume of traffic and miles of roadway in the
area. Both the volume of traffic and the miles of roads in the study area
are low. However, the relative volume of construction vehicles is high
and fuel oil does have to be transported to the east end of the Island on
the main road adjacent to Barlow Pond and the Middle Farm flats.
The parameters of greatest concern which would be
associated with fuel spills are benzene, toluene, xylenes, and other
hydrocarbons.
The roadways in some cases such as the one leading from the
Isabella Bluff area to the four corners intersection at the southwest
corner of Barlow Pond (near Bagley Reid's), concentrate and transmit
pollutants. The stormwater run-off turns and flows northward at the four
corners intersection and enters the Barlow Pond via a swamp near Bagley
Reid's house.
Oil, grease, low level lead, salt, sand and other
constituents are transported by stormwater toward the reservoirs. Of
course, oil or gasoline could also be transmitted into the ponds or
aquifer in the event of a spill or spills.
d. Salt Water Intrusion
Salt water pollution occurs in groundwaters as a result of
over pumping of aquifers near and open to the ocean. Another type of salt
water contamination of surface and groundwaters is aerosol migration of
wind blown salt water and sprays from wave action.
The Suffolk County Department of Health Services, Bureau of
Drinking Water has required the Fishers Island Water Works to implement a
monitoring program to detect salt water intrusion as a condition of its
approval of the recently installed public water supply wells.

e. Construction
Construction activities can promote erosion of soils which
could result in solids, nitrogen, solids, phosphorus and other
contaminants being transmitted to the reservoirs. In addition,
construction activities could result in overland flow to the surface
supplies or leaching into the groundwater of gasoline, oil, solvents,
paint, paint thinners, adhesive materials and other pollutants.
f. Animal Manure
Animal manure can result in pollutant loads on ground and
"":fd:e waters. The fecal matter contains BOD, nitrogen, phosphorous and
pathogenic organisms. The result can be increased coliform concentrations
and over nourishment of aquatic plant life. Although, few horses or other
domestic animals are within the public water supply tributary areas at
this time, more can be anticipated in the future.
The existing wild animal population, such as muskrats,
sguirrels, deer, ete. is not readily known. It is suggested that the
March 1993 Fishers Island Water Supply and Watershed Study Ecological
Component Report be referred to for additional information. However these
creatures can contribute significant pollution loads.
g. Water Fowl
Water fowl have been reported to be abundant on the
reservoirs. Water fowl discharge large quantities of nitrogen and
phosphorus in relationship to their body weights. Flocks of water fowl
can increase coliform concentrations in reservoir water beyond allowable
limits. These nutrients over nourish waterbodies resulting in aquatic
growths. During the reservoir sampling program, no water fowl were sited.
It is suggested that the Watershed Study Ecological Component of this
Report be consulted for a more definitive discussion of indigenous water
fowl. However, it has been reported that many water fowl have been observed on
all three reservoirs.

h. HaDDinq Potential Sources of Pollution
In order to identify potential sources of water pollution
within the Fishers Island water supply watersheds, the 1974 base map
furnished by the Suffolk County Planning Department was reviewed and
updated using 1988 aerial photos and field editing. The photos revealed
current residences, roads, driveways, lawns, drainage swales and other
pertinent information.
The mapping review and photographic editing was followed by
field edits of potential sources of pollution and coordination with Hr.
Robert Wall, the Water Works Superintendent, and coordination with Hr.
Hareld Cook of Gada, Inc., which supplies fuel oil and pumps septage from
the septic systems.
The field review included assessment of the residential
area, and facilities, edit of the watershed tributary area topography and
extent, identification of pollution pathways and review of the drainage
pdtt~:ns.
It was assumed that all residences are served by septic
systems, are utilized at least from Hemorial Day through Labor Day and
some are used for greater lengths of time. The water treatment plant is
not served by a septic system. Host residences are utilizing large fuel
tanks, and most have lawns and landscaped areas. The main road and
several driveways are paved. The remaining roads are combinations of sand
and gravel.
Sources of pollution within the water supply watersheds are
shown in Figure 5-1 at the back of the report. The residences, paved
roads, cleared areas and driveways are shown on the map. The septic
systems and fuel tanks are assumed to be near the buildings.

CHAPTER NINE
WET WEATHER SAMPLING AND ANALYSES
A. Introduction
This Chapter describes the wet weather sampling and analyses of
stormwater run-off entering Barlow Pond, Middle Farms Pond and Treasure
Pond.
B. Description
The initial approach to sampling and analyses of run-off included
flow measurements in swales leading to the ponds during storm events and
composite sampling of the run-off. However, after field observation
during storm events, it became obvious that the stormwater only
concentrated on paved roadways. The rainwater soaks into underlying sandy
soils rather than accumulating in swales. None of the drainage swales are
well defined except for a few leakoffs from roadways. The major leakoff
of roadway surface run-off is located near the southwest end of Barlow
Pond where the roadway dips to a low point. Stormwater run-off from the
Isabella Bluff area drains down to the intersection of the bluff road and
the main road and then flows to the aforementioned leakoff into a wetland
near the Bagley Reid residence.
Several other small roadway leakoffs are located northwest of Middle
Farms Pond.
An alternative stormwater sampling program was developed after
observation of the storm events and the response of staff gauges at the
reservoirs. This alternative program included sampling and analyses of
selected near shore locations at each pond. The locations were selected
based upon the locations of residences, i.e., the sample points were
located down slope from the residences near the edges of the ponds. The
stormwater sampling points are shown on Figure 5-1.
9-1
C. Sampling
Samples were collected prior to a storm event and immediately after
one. The initial set of alternative runoff samples were collected on
October 13, 1992, after a relatively prolonged dry period. The second set
of samples were collected on October 26, 1992, after a storm event on
October 25, 1992. The premise or theory is that the initial set of
samples during the dry weather period indicates the water quality prior to
a storm or base line quality information. The second set of samples
indicates the water quality after a storm event.
Th- sample puints, descriptions of the sample points and the types of
samples obtained are shown below in Table 9-1.

11. order to effectively evaluate the impact of existing on-site
wastewater disposal systems on the public water supply in the study area,
the following factors must be appreciated:
1. The seasonal nature of the inhabitants of the watershed areas.
2. The travel time for pollutants from on-site disposal systems to the
surface waterbodies.
3. The permeability and voids in the prDfiles Df the sDils present in
the study area.
~~e above factors present a unique situation in the evaluation of
bacteriologic analyses Df the waters frDm the study area. The pDpulatiDn
is at its greatest on Fishers Island frDm late June tD early September.
:1. the remainder Df the year, the number Df inhabitants dwindles tD almDst
ni: particularly in the study area.
Once established in a prDperly designed and maintained Dn-site
system, the "bic-crust" and geo chemical reactions remove bacteria, virus,
;:".,";:" c.r us, n itr Dgen, etc. prDvided there is adequate distance between the
grollndwater table, the "biD-crust" and any receiving waterbDdy.
Highly permeable soils, particularly those knDwn to have vDids in the
s:." profile can allDw rapid movement Df wastewater thrDugh the grDund.
Septic tank effluent requires three to six weeks Df residence in
groundwaters to insure bacterial dieoff. Viruses passing through the
"bio-crust" and entering the grDundwater can survive fDr much longer
periods than bacteria. The sDils in the study area are Df the Riverhead
and PlymDuth series. They are noted as possible pDllutiDn hazards and are
known to have voids which facilitate "piping" of groundwater through the
seil profile.
Sare,pIes of reservoir water taken in September frDm the Centers of
Barlow, Middle Farms and Treasure Ponds indicate IDw levels of
bacteriologic pollution in mid September under dry cDnditions. The wet
9-7
weather samples at the end of September rose slightly for Barlow and
Treasure Ponds. The Middle Farms Pond wet sample was substantially higher
(Total Coliform 260, Fecal Coliform 680, Fecal Strep 0) than the dry (TC
23 CFU, FC 0 CFU).
The water samples were taken at the reservoirs to evaluate runoff
impacts in mid to late October 1992. The dry samples were taken in mid
October, the wet weather at the end. The dry weather alternative runoff
samples for all three reservoirs had more bacteriologic pollution than the
later wet weather samples. The prime exception to this tend were the
samples from the wetland near the Bagley Reed residence (sample point B-4)
where the dry samples (TC 200, FC 18 and FS 10 rose to TC 420, FC 400 and
FS Ie).
The data are inconclusive. In order to properly evaluate the
impacts of the existing on-site disposal systems, a sampling program
beginning in early May should be undertaken to determine water quality
with most on-site disposal systems dormant. The sampling should progress
through the summer to determine if there is a slug of pollution entering
the reservoir due to septic tank "start up" and if there is any short
circuit flow to the waterbodies due to "piping" or heavy weekend use.
Finally, the program should run through the end of September which will
provide at l~ast six weeks of groundwater residence after a period for re-
establishment of on site disposal system use. Samples taken in the
October to April period, may be inconclusive due to dormant on-site
dispusal systems and surface water temperatures which limit coliform
organism "viability".
Establishment of solid baseline data on the surface supplies would be
a prudent action prior to further development in the study area.

CHAPTER TEN
TOPOGRAPHIC MAPPING AND DRAINAGE BASIN SURVEY
A. Introduction
The base mapping for the topographic survey was the Suffolk County
DPW 1" = 200' scale mapping. As previously discussed in Chapter 8, this
mapping was updated using aerial photos dated 1988 and field surveys were
conducted to check pond elevations, monitoring well elevations and grade
at the monitoring wells. Houses which had been constructed during the
interim period were scaled and plotted approximately on the base map.
The ARL survey crew field surveyed the major waterbodies and the
monitoring wells. Basic differences based on published benchmark
information were determined to exist, regarding the surface elevations of
Barlow Pond, Middle Farms Pond, Treasure Pond and Island Pond as shown in
the following table (10-1).
TABLE 10-1

MAP ELEVATIONS
Barlow Pond 6.0+ 10.5
Middle Farms Pond 7.9!. 12.5
Treasure Pond 7.9i 12.5
Island Pond 3.9i 3.0
In addition, the survey crew obtained grades and tops of well casings
at the 11 monitoring wells and 1 boring, and set benchmarks and staff
gages at all three reservoirs for rainfall response testing. The
elevations on the map were compared with our surveyed elevations. Some
differences were apparent.

Field edits of the reservoir watersheds and the infiltration gallery
areas were conducted during the early stages of the project to identify
the extent and configuration of the watersheds and to investigate the
locations of roadway leakoffs, culverts, drainage ways, manholes on the
infiltration gallery and other items.

It was concluded, based upon the old plan showing a pipe interconnec-
tion between Treasure Pond and Middle Farms Pond, the topographic mapping
and the survey, that the gate is open and the ponds are hydraulically
interconnected via the pipe.

CHAPTER ELEVEN
TYPICAL SEPTIC TANK ANALYSES
A. Introduction
Septic systems discharge bacteria, viruses, nitrogen, phosphates and
metals trace organics to the groundwater.
Bacteria survive for 3 to 6 weeks in soil. It is assumed that
ccli:8~rr bacteria i~ septic systems originate in the human intestine. The
presecce of the coliform indicator organisms infers the possible presence
of pS':ho'::Jer,ic organisms. In sensitive areas such as water supply
watersheds, analyses of the time of travel of bacteria should be done
prior to co~struction of a septic system.
B. M2t:l0d of Analysis
Time of travel analyses utilizes the soil permeability, porosity and
hydrau:ic gradient to arrive at the velocity of groundwater movement.
v = K i
N
Where V = Velocity (ft/day)
K = Permeability (ft/day

The estimated values for areas around the Barlow Pond Watershed
are as follows:
K = 50 ft/day for fine to medium sand
i = 0.043 (perched water table)
N = 0.35 estimate
6 ft/day x 21 days = 126 foot set back required.
It should be noted that the K values or permeabilities vary
greatly. The range could be 25 ft/day to 150 ft/day. The Suffolk County,
New York USDA Soil Survey classifications for the upper soil layers in the
walershed area indicate that the permeabilities (K) are greater than 12.6
ft/day and range up to 150 ft/day. Based upon ARL visual observations,
boring logs and grain sizes of the soils near Barlow Pond, the estimated
permeabilities (K) range up to 150 ft/day. The permeabilities of the
soils south of the pond and between Barlow and Island Ponds particularly
ap"oa,- to be of moderately high (5 to 25 ft/day) permeability. However,
in order to properly evaluate a specific site, particularly in this very
sensitive area, in-situ or laboratory permeabilities should be determined
at aeveral points and elevations within the proposed septic system
location.
Viruses have been found to travel long distances in saturated
sandy soils. However, if an unsaturated distance of about 2 feet exists
below an established biological growth layer of a leaching system, the
viruses are removed.
Domestic sewage contains organic, ammonia and nitrate nitrogen.
Septic tank effluent leaves the tank in the organic or ammonia
condition. The stone-soil interface on a leaching system normally creates
an aerobic condition. The ammonia is oxidized to nitrite - nitrate

nitrogen. Nitrate moves readily in the groundwater table. A typical
requirement is that the nitrate concentrations remain below 10 mg/L as N
for health purposes. A major concern in reservoir watersheds is excessive
nitrogen concentrations in the ponds which causes over nourishment of
aquatic plants. This can result in reservoir infilling and taste/odor
proLlems.
Al thougtl septic tanks contr ibute to the nitrogen concentrations in
surface and qroundwaters on Fishers Island, it is the opinion of the
Suffolk County Health Department that nitrogen concentrations in these
waters due to turf management practices is more significant. The zoning of
low de~sity housing, the brief seasonal occupancy which predominates on
FisII'"rs Island and the absence of housing on the majority of the watershed
appears to support thi~ conclusion.
Procedure for nitrogen computations:
ASCU~E ' bed:oom house with two people per bedroom
1. 3 bedrooms x 2 oeoole x 75 gpcd = 450 gpd, 450 gal/day x 3.8 liter/gal

= 1710 L/day
2. Typical concentrations 40 mg/L, 40\ removed by pretreatment, therefore
1710 L/day x 40 mg/L (1.0 - 0.4) = 41,040 mg/day
,
o.
Rainfall for dilution, 250 ft x 250 ft = 62,500 sq ft
precipitation 0.01 ft, 2Ql infiltrates, therefore 375
or 2805 gallons or 10,659 L.
average daily
cu ft/day
4. Delivery to site, 1710 L/day at 24 mg/L = 41040 mg/day
Dilution, 10,659 L/day t 1710 L/day = 12,369 L/day
5. Final concentration 41,040 mg/day/12,369 L/day = 3.3 mg/L
6. Drinking water standard 10 mg/L therefore the discharge is ok.
11-3
The nitrogen computation of 3.3 mg/1 for a 250 ft by 250 ft
appears to compare well with modelling ('Protection and Restoration of
Ground Water in Southhold, N.Y.," Trautman et aI, Cornell University,
1963) and actual sampling ('Suffolk County Comprehensive Water Resources
Management Plan" [CWRMPl, SCDHS, Dvirka and Bartilucci, and Malcolm
firnie, Inc., 1987) performed for other Suffolk County and Cornell
studies, which indicate an average nitrogen concentration of approximately
3.8 to 3.9 mg/1 in areas with one dwelling unit per acre.
Article 6 of the Suffolk County Sanitary Code limits development
in non-sewered areas to 40,000 square feet per single family home (or its
equivalent in terms of 300 gpd of sanitary flow) in Hydrogeologic Zones
3,', and 6, and 20,000 square feet per unit (medium-density) with average
;roundwater nitrogen concentrations of 4 ppm and 6 ppm, respectively
(comparing well with the CWRMP and Cornell reports). The goal of the
Article 6 regulations is to ensure that nitrogen does not exceed the
lOmg/: c1rin};ing water limit.
Phosphate can trigger eutrophication of surface waters if it is
the limiting nutrient. Phosphate generally has a concentration af 20 mg/L
in domestic sewage. Some researchers such as Shawney and Hill subscribe to
the theory that soils absorbs phosphorous. As the groundwater fluctuates,
Q soil section that ha5 been absorbing phosphate is left with no recharge.
Over a 6 month period, phosphate will combine with Iron (Fe), Aluminum
(Al), or Calcium (ea) to form less soluble precipitates. The original
absorption sites are then regenerated. This theory results in the following
computation:
Nornlal domestic waste concentration is 20 mg/L
40% removal by biacrust & septic tank: 20 mg/L x 60\ = 12 mg/L
Ahsorption rate by soil: 22 mg/lb. of soil
Jaily flow to septic system (600 gal/day) (3.8 L/gal) = 2271 L/day
ro = 12 mg/L x 2271 L/day = 27,252 mg/day

Soil weight: 120 cf x 120 lb/cf = 14,400 lb/cf
Absorption per foot: 14,400 Ib/cf x 22 mg/lb = 316,800 mg/ft
Distance traveled per day: 27,252 mg/day - 316,800 mg/ft = 0.087 ft/day
Distance traveled in 6 months: 0.087 ft/day x 30 days x 6 months = 15.6 ft
Distance available: + 120 ft
Other prominent investigators such as Vo11enwi1der and Dillon
of the Ontario Institute in Canada subscribe to the theory that a phosphate
wedge continues toward the surface water at a continuous steady state
rate.
Trace organics ranging from household cleaners to paints and
solvents can be found in some septic systems. Sometimes septic tank
additives which contain organic pollutants are used on septic systems.
Some trace organics can move readily in the groundwater.
It can be concluded that drought conditions result in
groundwater flows toward the ponds and aquifer and possible pollution of
them. The pathways of pollutants from septic systems to the three (3)
pond" s;-,d the Middle Farms Flat aquifer should be carefully evaluated
prior to any additional construction of residences.
