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
Barlow Pond Infiltration Gallery (underdrain) 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
the water available from existing sources (reservoirs and wells), 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 Year 2015 requirements.
Conclusions
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 two wells currently pumping water for the entire Island's use on a
westerly segment of Middle Farms are certainly adequate for the better
m 1_1
part of a calendar year. Because of the huge increase in summer demand,
however, and because of the twin dangers of salt-water intrusion and ih~
drawing down of nearby wetland level to a dangerous degree, it would be
far better and more conserving of a vital natural resource if the surface
water ~reafment plant on Bar/ow Pond [that used to serve the ~nt]re Islan]~
remained on standby and in good working condition - all in readiness ]est
a severe drought or the dangers mentioned above damage the Middle Farm~
underground aquifer.
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
-~minat~ the publi~ water supply. These po~ntSal sources
contamination are listed in Tables 8-l, 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
sourc~ in areas of low density development. EPA 502.z analysis fo~
limits specified for ali surface and groundwaters sampled.
4. The ]atoratory analysis for Pesticides and Herbicides yielded negative
results at the detection limits for the contaminants specified in the
scope of study.
5. Water from Bari.ow Pond, Middle Farms Pond and Island Pond flows
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 (327) acres. It lies about two 12! feet above mea~.
sea level, passes under a number of glacial kettle holes and appears to be
well ~ituated to intercept groundwater flowing seaward from tho Isabella
Bluffs area. Flow from the gallery can be controlled by a valve id
h~nhole Number 2 near ~arlo~ Pond.

Recommendations
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.
3. Prepare a Drought Management Plan.
4. To guard against pollution, all present and future water wells in
public use, as well as the three surface reservoirs on Fishers Island,
should be mapped and tested thoroughly and periodically. The testing (for
minerals and pollutive chemicals such as pesticides and herbicides) should
be don~ twice a year, with at least one test coming in the summer months,
after a heavy rainfall.
5. Replace the missing manhole covers on the Barlow Pond Infiltration
Gallery with locking frames and covers.
6. In case of property development and attendant pollution that would
compromise the water quality of Barlow Pond, emergency pipelines should be
refurbished, prepared, and if necessary constructed to tap alternative
surface water supplies. These supplies can be found at Middle Farms Pond,
Treasure Pond, and possibly Brickyard Pond. The first two named are
already classed as Island reservoirs, and both water quality and quantity
are good enough to serve the whole Island in a pinch - even in summer.
These emergency pipe ines should be run directly to ~ Barlow Pond
pumping station an to Barlow Pond. Certainly both Middle Farms Pond
and Treasure Pondlshould maintain their status as surface reservoirs.
7. As a final step to insure clean and plentiful water supplies well into
the 21st century, a new back-up well drilling program to supplement the
current wells on west Middle Farms could be begun and sponsored by the
I 1-3
Fishers Island Water Works, using both this study and previous studies of
Fishers Island aquifers as a guide in locating possible well locations
It should be emphasized that any back-up wells of this nature, ne matter
how prolific, will not and should not cancel out the need for maintaining
the Island's surface reservoirs as sources of potable water. On an Island
where almost all locations are within 1/4 mile of the sea, any and all
well locations are candidates for salt water intrusion and/or dangerous
g:':w-down of key wetland habitats.
Additional Environmental Issues
Several issues have been raised regarding environmental
investigations on Fishers Island since the scope of this r~-t was
defined and established in our contract. These issues include additional
evaluations of the following items listed in order of watershed
protection/supply impr. rtance:
i. Surface area tributary to the wellfield and potential sources
2. Analysis of monthly billed water, metered production, popnlation,
leakage, and other factors influencing historic and future monthly and
annual water demand.
Brickyard Pond as potential source of surface water supply
4. The Farlow Pond Infiltration Gallery yield and fh~ influence, if any,
of the pond near the Chip Dupont residence.
5. The potent]a/ pollution of the Barlow Pond Infiltration Ga~,.rf b'~ the
Pickett Landfill.

CHAPTER THREE
WATER BUDGET AND DESCRIPTION OF EXISTING WATER SUPPLY SYSTEM
Water Supply System
The Fishers Island Water Works System was constructed in the early
1900's to provide potable water and fire protection for the Island.
The system services approximately 600 customers utilizing 22 miles of
water mains, an equalization reservoir, a surface water treatment plant, a
groundwater treatment facility, a well field and three surface water
reservoirs. There are no dams.
The sources of surface water include Barlow Pond, Middle Farms Pond
and Treasure Pond. Barlow Pond has been augmented in the past, especially
during the 1960's drought by transferring water from Middle Farms Pond
ssing temporary pipes and pumps. Water is pumped directly from Barlow
Pond into the treatment plant.
The one (1) million gallon per day surface water treatment plant
was constructed during the 1920's. The treatment process includes
aeration, coagulation, sedimentation, filtration, pH adjustment and
disinfection. However, it was removed from service during 1990 and is on
stand-by. The plant is located adjacent to, and draws its supply from
Barlow Pond.
The sources of groundwater supply include the "SIMA" well, the
"Church" well and the "Hers" well. The well water is of good quality
except for its iron content which is relatively high. Iron effects water
taste and odor and can clog well screens. Iron also stains laundry and
plumbing fixtures.
A groundwater treatment facility was recently constructed 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 untreated well water can be pumped to Middle Farms Pond te
augment the surface supply, and to dilute the concentrations that the
treatment facility, when operating, would treat.
The distribution system consists of mostly unlined cast iron mains,
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.
The 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-
day 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 ifs present rate.
During 1988, Buuk and Bi~k Engineers of gartfor~, CT prepared s
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
Farms Pond during 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/1 (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 d~str~but~on system. HoweYer, thls method is
suitable only for concentrations up to 1 mg/1. Iron concentrations in
excess of 0.3 mg/1 are unsatisfactory. If manganese is present, the
allowable total of iron and manganese is 0.5 mg/1.
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 budget can be described algebraically as follows:
WS = DP + SR + I - E - ET - Consumption
Where WS is Water Surplus
DP is Direct Precipitation
SR is Surface Run-off
! is Infiltration into the Well Field Cone of Depression
E = Evaporation from Pond Surfaces
ET = Evapotranspirat]on 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
3-3
of April, 1990. Surface run-off for the sandy soils and extremely brushy
watershed based upon review of the above mentioned report is about 15%.
Many rain events were observed during the field work, however run-off was
observed only at the low points of the roadways. No rivelets 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 Middle Farms
Flats aquifer is estimated to be 90% of the precipitation which does not
transpire or evaporate.
Evaporation on Fishers Island ranges from ]2 inches to t7 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
Water Works, Inc. is 87 million gallons for the year 2015. This data was
taken from "Report on F~sbers Island Water Works", dated ~n.'~ry 29i ~a~,
by Buck & Buck Engineers of Hartford, Connecticut.
The areas of the reservoirs and watersheds are listed in Table 3-1.

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

the usable pond storage which has been estimated by Buck and Buck,
Inc. to be 114 million gallons would be utilized.
The water budget during a drought using the Well Field and

would yield the following:

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 C02, iron, manganese,
phosphate, and sodium. Bacteriological analyses included total coliforms,
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 mg/1 for all three ponds.
Nitrogen for all three water bodies was typical for small northeastern
reservoirs with low density developed watersheds on both sampling
occasions.
4-1
Chlorides were in a similar range for all three ponds. The chloride
content of about 30 mq/1 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 pond~ w~s
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 Ag/l) whereas Middle Farms Pond was lower at 0.16 ppm and Treasure
Pond was very low at less than 0.01 mg/1. 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 clarificafion of ~he backwash water which would allow iron to setti~
out. The Bureau of Drinkin§ Water believes the backwash water c]arifier
h~ not beer ,~=~ }n many y~ars due to a broken line.
£=~.=.=~ samples rev=~d b~t~zi~i c~nt~nt The Barlow [~o~d ~ample
indicated 5, 2 and 3 per 100 A1 for total coliforms, fecal coliforms and
fecal streptococcus respectively during the 9/17/92 sample and 20, 18 and
2 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 RI 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 hydrogeolo~ic report published April
1990, by Ground Water, Inc., and existing and potential future sources of
pollution 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 described by U.S.G.S. as "sand plain deposits" which are sand and minor

l
gravel underlying "sand plains" lO to 20 feet above sea level on Fishers
Island.
Based upon the boring logs for monitoring well I1 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.G.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.G.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. Gordon 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 15 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.G.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 iE
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 Bar]ow 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 Reed's residence at the south end of Barlow Pond. Thp soil to a
?~Sf]~ >f i' L~et is light brow~ fine t, mediu~ sand, with a trace cl
silt. The so]Is 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
water yielding material and the location with respect to the water
d~ve]~ped 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
hole (B-l) about 12 feet from the monitoring well ~ and explore the
Sn~slbility of a new water supply well. The boring log and observations
~od]cate that the soil is not sufficiently permeable for a h~gh yield
water supply well.
Monitoring well #7 located south of Middle Farms Pond near the Miller
residence remulted in light b~nwn fin~ to medium san,~ with a trace cf 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 fee~
per day.
Monitoring well #8 boring and soils observations were conducted to a
d~pth of 1[1.5 feet. This boring and well were installed deep to

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 sumn~ry,
the m~terial 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
aquifer 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
depression 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 the 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 pollutants would most likely travel slowly in this soil.
The monitoring well #10 is located adjacent to the main road north of
the Bafferty 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 permeahilities and fits the description of
end-moraine deposits.
The boring and monitoring well Ill 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 #11 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 mow
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.
Th~ dir n and j'~di~nt of the grnundwater surfaces around
the ponds determines the destination and velocities of pollutants within
the oquifer.

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:

were then determined

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 Samnlina and Analyses
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 residences 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
chlor]des to dete:mine 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

· ' 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/1 and 0.17 mg/1 respectively.
The field pH was low at 5.7
Monitorin~ 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/1 indicating most likely decaying vegetation. All
other constituents were low, indicating good quality water. The field pM
was low at 5.2.
Monitoring Well ~3 was not sampled because it was installed to
determine soils and groundwater characteristics only.
Monitoring 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/1 and nitrates were above background levels indicating
some probable human impact on the groundwater quality. The field pH was
Iow at 5.7.
Monitoring 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/1
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/1. This elevated
nitrate cannot be explained at this time. The pH was 6.5 which most
likely indicates the influence of Barlow Pond water.
Monitoring Well ~6 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/1.
Monitoring Well #7 was located south of Middle Farms Pond and several
residences. The gradient of the groundwater indicates that the flow was
most likely from und~ at least one residence. It i~ possib]~ ba~ed upon
review of the topography, that groundwater flows from under several of
these £e-~d~I,,es. No VOC's, pesticides or herticides we~= [~ ".d.
Albuminoid nitrogen content was high at 0.96 mg/1 which may be the result
of human activities or natural decay of vegetation. Nitrate nitrogen was
elevated above background levels at 1.18 mg/1 indicating possible
fertilizer or septic system influence.
Monitoring Well #8 is a 150 feet deep well west of Middle Farms Pond.
The purpose of this well was the determination of soils characteristics
and potential chloride intrusion at deep depths. The chloride content was
elevated at 30 mg/1 which is not extremely high for this area. Monitoring
well 2D which was installed about 600 feet south of MW 8 had 91 mg/1
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/1
of chloride concentration does not seem excessive. However, in view of
the relatively low chloride concentration at 150 feet deep in MW #8, the
concentration of 91 mg/1 in MW 2D which is about 80 feet deep does seem
excessive and should be monitored very carefully and frequently.

Monitorin~ Well 19 is located near the main road, north-northwesterly
of Middle Farms Pond. The groundwater gradient indicates that water flows
from Middle Farms Pond toward Fishers Island Sound through the Laughlin
property.
Monitoring 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 Sound and most likely flows under a
residence.
The conductivity at 220 micromhos, the manganese at 1.3 mg/1, the
nitrate nitrogen at 12.4 mg/1, the pH at 7.1 and the sodium at 26.0 mg/1
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.
Monitoring We]] ~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 wel! 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 18 in the future.
No VOC's, herbicides or pesticides were found. Albuminoid nitrogen
and manganese were elevated. However, no sources of pollution were
indicated to be present.

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. Description
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
clearl~ 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 ~773. 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-zag~ about 500 feet northeast across the DuPont land to
an un-named road. It then turns about 20 degrees in an easterly directb~
and extends about 400 feet to Grey Gull Lane. It then turns northward and
extends about 1,700 feet to the intersection of the Bar]ow Pond Roadway
From this point, it e×tends about 300 feet to a point that extends
approximately 25 feet into Barlow Pond.
The pipe is tile, based upon the field observations, discussions
Mr. cavanaugh Iwho bas indicated that he worked on the construct]on 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 6~rlow
?ond is mnst /i~ly 15 inches diame*er.
Manholes l, 2, 5 on the map shown in Figure 6-1, and two more near
the swamp behind the 5uPont house were found and inspected. They are 5
foet diameter brick and mortar manholes.
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 e×ceptior~ cf
manhole ~5, whioh she, uld be repaired.
Manhole #2 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
sbnuld be pumped an~ examined.
C. Tributar~ Area
The total infiltration gallery tributary surface area is about !27
acre5 as compared with Barlow Pond's 31 acre tributary area. The surface
tributary area extends southwesterly to within 300 fe~t of the Pb?ket:

Landfill. About 92 acres of land between the main road and the Isabella
Bluffs contribute surface water to the drainage ditches near Pole ~773 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
towards it, the total 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
"Infiltration 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
investigations 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
to 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
A~other key piece of evidence that the drab', was extended to augment
the Bar]ow Pond water supply ia the fact that an abandoned well field lies
immediately southwesterly of the pond. The well f]~]d bad numerous we]]
points, an ~laborate suction manifold, a huge gasoline driven pump and a
raw water main extending toward Bar]ow Pond. It was most likely used to
supplement the Barlow Pond water supply. Therefore, we conclude the need
for Barlow Pond augmentation e×ist~d d',ring early years.
Flow Evaluations
No movement of the existing water was noted during numerous
inspections of m~i~noles 1, 2 and 5. Substantial overland fi.~ f~om th~
northwes~ s]npes cf the isabella Bluffs has been observed enterlng the
head wails of the conduit near the main road and Pole ~773, and
substantial flows have been seen entering the cracked mortar of Manhole

Dye tracing of flow between Manhole ~1 and Manhole ~? near Bar]ow

It can be hypothesized that during rainstorms, the Barlow Pond water

the Fishers ts]~nd Water Works Supervisor, ind]=oted that when i+ rain=

rises more slowly and therefore forms a sink to accept flow, and results
in flow away from Barlnw Pond.
During drought conditions, the flow would be reversed toward
Pond, and the infiltration gallery would provide added water · [.~

to Barlow Pond. The drain and surrounding aquifer provide additional
water sturage. 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 nnderdrain.
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.
6-5
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 Bar/ow 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
underdra]n 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 flow~
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 ms l. 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 l~kely
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
th=t polluted run-off f-om th~ roa north of t]~e well field cou]~ 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 ~2 and greater than 38 feet at MW
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
MW ~8, it is about 100 feet deep and at MW 2D 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 buring
data, it Pay be concluded that the aquifer thickens as it extends from the

well field area to Middle Farms Pond and it is not confined. It is
probable that water flows from Middle Farms Pond into the well field.
Figure 7-2 shows the cross-section line on a topographic map.
Monitoring wells 12, 5, MW2D and 8 are shown on this map because they
were used to determine cross section characteristics.
In order to illustrate the effect of droughts or drawdown on the
pathways of pollutants, and to illustrate general 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 from Barlow Pond and the west end of
Middle Farms Pond.
Figure 7-4 shows a condition which cuuld exist during a drought.
Barlow Pond's water elevation was 1.5 feet msl during the 1960 drought.
During the drought period the gradient reverses. This condition would be
worse in the southwest and northern edges of Barlow Pond. As previously
mentioned, the result would be travel 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 the following point sources:
Residential septic systems
O]1 storage tanks
Swimming pool discharges
Non-point sources include:
Herbicides and pesticides used for lawns, shrubs and gardens
Fertilizers used for lawns and shrubbery
Roadway runoff
Salt water intrusion of ground and surface waters
Construction erosion and sedimentation
Animal manure
Water fowl
8-1
1. Point Sources
a. Residential On Site Disposal Systems
Many of the existin~ on site wastewat~r di=~a] Sybte~L=
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.
Bacteria including fecal colifor~ 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 cf 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 lime D
saturated soils and will therefore travel grea[
d~t~nces (Jr +~v sur~["c' to reach the ~r _.~ ~.
level. The critical safeguard is maintenance of a_Sn
adequate 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.
Nitrogen~ N in the form of nitrate ion (NO3 ) is
considered a pollutant if it exceeds the concentration
of greater than 10 mg/1 as N according to the U.S.
Public Health Service. The nitrate has been known to
cause an infant disease known as Methemoqlobinemia.
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,
photograp~~ chemicals and other ho,~=e~o!d
Some septic system additives contain organic chemicale
which enter and pollute groundwaters.
In addition to groundwater pollution, failed septic
systems within the watershed could result in overland
flow and water po?~ut~on w!th trace organics.
Normally, some trace organics will be removed in the
soils by volatilization, chemical reactions, and
absorption.
b. Heating Oil Storage Tanks
Heating oil storage tanks, especially underground tanks can
rust and leak causing contamination of s~.ii_ and the ~[oundw~t=~. Mu=~ ~,
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 (RTH), stabilizing acids such ae cyanatic acid, algae, alkalinit3
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 samples analyzed for this study is most probably indicative of
presence 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
reservoirs and 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 BUD, 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 b= transported to the east end of the Is]~n~ 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, ~rease, i~,w i~vel 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
surface waters. The fecal matter contains HOD, 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,
squirrels, deer, etc. 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
ail three reservoirs.
8-7
The potential sources of pollution from existing residences
within the study area are shown in Tables 8-1 through 8-4.

Mapping Potential Sources of Pollutfon
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 Mr.
Robert Wall, the Water Works Superintendent, and coordination with Mr.
Rarold Cook of Gada~ Inc., which supplies fuel oil and pumps septage from
the septic systems.
The field review included assessment of the residential
areas and facilities, edit of the watershed tributary area topography and
extent, identification of pollution pathways and review of the drainage
patterns.
It was assumed that all residences are served by septic
systems, are utilized at least from Memorial Day through Labor Day and
some are used for greater lengths of time. The water treatment plant is
not served by a septic system. Most 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.
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. Sam~lin$
Samples were collected prior to a storm event and immediately after
one. The initial set of alternative runoff samples were collected on
Octut~< 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.
The sample points, descriptions of the sample points and the types of
samples obtained are shown below in Table 9-1.

In 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.
The travel time for pollutants from on-site disposal systems to the
surface waterbodies.
The permeability and voids in the profiles of the soils present in
the study area.
The above factors present a unique situation in the evaluation of
bacteriologic analyses of the waters from the study area. The population
is at its greatest on Fishers Island from late June to early September.
In the remainder of the year, the number of inhabitants dwindles to almost
nil particularly in the study area.
Once established in a properly designed and maintained on-site
system, the "bio-crust" and qeo chemical reactions remove bacteria, virus,
phosphorus, nitrogen, etc. provided there is adequate distance between the
groundwater table, the "bio-crust" and any receiving waterbody.
Highly permeable soils, particularly those known to have voids in the
soil profile can allow rapid movement of wastewater through the ground.
Septic tank effluent requires three to six weeks of residence in
groundwaters to insure bacterial dieoff.' Viruses passing through the
"bio-crust" and entering the groundwater can survive for much longer
periods than bacteria. The soils in the study area are of the Riverhead
and Plymouth series. They are noted as possible pollution hazards and are
known to have voids which facilitate "pipinp" of groundwater through the
soil profile.
Samples of reservoir water taken in September from the Centers of
Barlow, Middle Farms and Treasure Ponds indicate low levels of
bacteriologic pollution in mid September under dry conditions. 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 runofi
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 10].
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 tn 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 least 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
disposal 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. Rouses 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
WATER SURFACE ELEVATIONS (MSL)

MAP ELEVATIONS
Barlow Pond 6.0+ 10.5
Middle Farms Pond 7.9A 12.5
Treasure Pond 7.9~ 12.5
Island Pond 3.9~ 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 inYestigate 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
coliform bacteria in septic systems originate in the human intestine. The
presence of the coliform indicator organisms infers the possible presence
of pathogenic organisms. In sensitive areas such as water supply
watersheds, analyses of the time of travel of bacteria should be done
prior to construction of a septic system.
B. Method of Analysis
Time of travel analyses utilizes the soil permeability, porosity and
hydraulic gradient to arrive at the velocity of groundwater movement.
V = Ki
N
Where V = Velocity (ft/day)
K = Permeability (ft/day
i = The Hydraulic Gradient
N = Porosity of the Soil
11-1
The estimated values for areas around the Barlow Pond Water~he.~
are as follows:
50 ft/day for fine to medium sand
2..343 [perched w~tcr table]
0.35 estimate
V = K__i = 50 ft/day x 0.043 = 6 ft/day
N 0.35
6 ft/day x 71 days 1~6 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
watershed 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
appear 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 several 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
problems.
Although septic tanks contribute to the nitrogen concentrations in
surface and groundwaters 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 density housing, the brief seasonal occupancy which predominates on
Fishers Island and the absence of housing on the majority of the watershed
appears to support this conclusion.
Procedure for nitrogen computations:
Assume 3 bedroom house with two people per bedroom
3 bedrooms x 2 people x 75 gpcd = 450 gpd, 450 gal/day x 3.8 liter/gal
bedroom
= 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
Rainfall for dilution, 250 ftx 250 ft = 62,500 sg ft average daily
precipitation 0.01 ft, 60% infiltrates, therefore 375 cu ft/day
or 2805 gallons or 10,659 L.
4, Delivery to site, 1710 L/day at 24 mg/L = 41040 mg/day
Dilution, 10,659 L/day + 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 ky 250 ft
appears tn compare well with modelling ('Protection and Restoration of
Ground Water in Southhold, N.Y.," Trautman et al, Cornell University,
1983) and actual sampling ('Suffolk County Comprehensive Water Resources
Management Plan" [CWRMP], SCDHS, Dvirka and ~artilucci, and Mal-o]m
Pirnie, 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 n~n-=ewered areas to 40,000 square feet per single family home [or its
equivalent in terms of 300 gpd of sanitary flow) in Hydrogeologic Zones
3,5, and 6, and 20,000 square feet per unit (medium-density) with average
groundwater 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 doe5 not exceed the
10mg/1 drinking water limit.
Phosphate can tzi.~ge: ~:.~rophi£at[ of surface waters if .t .£
the limiting nutrient. Phosphate generally has a concentration of 20 mg/L
in domestic sewage. Some researchers such as Shawney and Hill subscribe to
the theor}' that soils absorbs phosphorous. As the groundwater fluctuates,
a soil section that has been absorbing phosphate is left with no recharge.
Over a 6 month period, phosphate will combine with Iron (Fe), Aluminum
(Al), or Calcium (Ca) to form less soluble precipitates. The original
absorption sites are then regenerated. This theory results in the following
computation:
Normal domestic waste concentration is 20 mg/L
40% removal by biocrust & septic tank: 20 mg/L x 60% = 12 mg/L
Absorption rate by soil: 22 mg/lb, of soil
Daily flow to septic system (600 gal/day) (3.8 L/gal) = 2271 L/day
PO = 12 mg/L x 2271 L/day = 27,252 mg/day
Calculate absorption in one foot section of soil:
1 ft (width) x 1 ft (height) x 120 ft (length of system) = 120 cf

Soil weight: 120 cf x 120 lb/cf = 14,400 lb/cf
Absorption per foot: 14,400 lb/cf x 22 mg/lb = 316,800 mg/ft
Distance traveled per day: 27,252 mg/day - 316,000 mg/ft = 0.087 it/day
Distance traveled in 6 months: 0.087 it/day x 30 days x 6 months = 15.6 ft
Distance available: + 120 ft
Other prominent investigators such as Vollenwilder 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
ponds and the Middle Farms Flat aquifer should be carefully evaluated
prior to any additional construction of residences.
