WATER SUPPLY REPORT
ANGEL SHORES
SOUTHOLD, L.I., NEW YORK
INTRODUCTION
The Angel Shore project consists of a proposed 29 lot
subdivision on Main Bayview Road in the Town of Southold
Long Island, New York. As five individual 2" test wells
were driven in various locations on the site resulting in 4
unsatisfactory wells and 1 satisfactory well, (see test
results in Appendix A), The Suffolk County Health
Department required a community well and water supply
system. Based on the test results of these five
preliminary test wells, the proposed well site and a 200'
radius protection field were proposed on Lot 1, thus
reserving Lots 1, 2, and 3 for the protection field, (see
proposed well site). Therefore, the community water supply
system was originally intended for 26 single family lots.
The site plan .has since been modified, allowing maintenance
of a 200 foot protective radius while using only two lots.
The system has therefore been modified to serve 27 single
family lots at Angel Shores.
The Angel Shores subdivision has since been expanded with
the original 27 lots comprising Section 1 and an additional
24 lots immediately east of the first section forming
Section 2, bringing the total number of lots in the Angel
Shores subdivision to 51.
Test wells were driven at the proposed well site and a
pumping test was performed using a conservative rate from
which was derived the original design critera of this
report.

Subsequent Revisions
It was subsequently proposed that the Angel Shores water
supply be constructed with sufficient pumping and storage
capacity to also serve the proposed subdivision known as
the Cove, to be located approximately 4900 feet from the
Angel Shores project. The Cove is to consist of 33
condominium units, bringing the total to be served up to
84. This substantially increases the projected water usage
and requires greater pumping and greater storage capacity.
Additional pumping tests were performed in January of 1986
in order to observe the time needed to stabilize the well
drawdown at the increased flow rate and d~monstrate that
chlorides would not appear at the increased flow rate.
Based on the well test and pumping test performed on the
proposed well site, the quanity of water is more than
satisfactory and no significant draw down on the
groundwater regime occured.
Summary of Revisions
1. Angel Shores prOject has increased from 26 to 51 units.
The water supply plant will also serve a
known as "The Cove", consisting of 33
units.

Required Quantity of Potable Water
Based on 100 single family units at 3-1/2 persons per unit
and an average per capita demand of 100 gpd, we calculates

This calculation is based on the use of three 30 gpm wells
with a maximum of two wells running a peak times with the
third as a backup in case of well malfunction for a maximum of
60 gpm during peak demand. Please note that the above
calculation is tabulated using 100 single family units, this
is based on the servicing of 84 units plus a 15% ~ contingency
which yields a more conservative design.
HENDERSON AND BODWELL ~ONSULTING ENGINEERS
Well Testing
The following well tests were performed in the proposed
location, (see Site Plan), to obtain quantity and quality
assurances. First a 2' dia.'well was driven to a depth of
57 feet, the well was then pulled back every 5 feet, pumped
off and sampled for choride, nitrate and iron. All samples
were analyzed by New York Testing Laboratories Inc.., of
Westbury, New York. The results from this first test can
he found in Appendix B. Next the depth of the supply well
was selected based on the test results of' the first test
and various requirements of the Suffolk County Health
Department. A four inch test well was installed to a depth
of 53.5 feet. The well was pumped at a rate. of 40 gpm for
a 7 hour period on two separate occasions. Water samples
were secured by both Henderson and Bodwell and the Suffolk
County Health Department. Results can be found in Appendix
C and Appendix D.
These tests provided sufficient evidence that the water
quality is satisfactory and well within the New York State
guidelines, and that the well was capable of producing a
' free yielding supply with negligible draw down on the
surrounding groundwater regime. Therefore, this source
should be more than adequate in supplying the Angel Shore
development.
Additional Well Testing for Expanded Project
On January 7, 1986 and January 22, 1986, the existing test
well was operated at a flowrate of 60 gallons/minute.
Samples were taken by the Suffolk County Department of
Health Services on January 7 (Start, 3 hr and 7.5 hr) and
by Henderson and Bodwe11 on January 22 (Start, 2.5 hr and
drawdown measurements). Samples taken on January 22 were
taken to Ecotest Laboratories, North Babylon, New York.
HENDERSON AND BODWELL CONSULTING ENGINEERS
Samples analyzed by the County were generally well within
New York State limits with the exception of iron, which
fluctuated widely (0.01 - 3.91 mg/1 vs. a limit of 0.3).
Samples analyzed by Ecotest (for iron and manganese only)
were within state drinking water limits. It is proposed
that a polyphosphate system be included as a precautionary
measure in the event that transient iron concentrations are
encountered. It is also proposed to install an
automatically operated blowoff valve system which would
purge the water initially pumped from a well during
startup. The (pilot-solenoid) valve would be energized by
a timing relay which in turn would be started by either of
the well pump motor starters. A third well will also be
installed to serve as a backup in the event of a well pump
malfunction.
Water Quality
Based on the test results from samples taken during the
initial well test and during the 7 hour pumping test, the
overall guality of the water is satisfactory. Samples were
collected by both Henderson and Bodwell and the Suffolk
County Health Department.
The initial well test compared chloride, nitrate and iron
levels at various depths to determine the best depth for
the community well. These results can be found in Appendix
B. They indicate chloride levels ranged from 16 to 31,
nitrate levels ranged from 0.3 to 7, and iron levels ranged
from .05 to 0.17. All levels were well under the
allowable.
~u:in] the pumping test samples were secured by Henderson
and Bodwell at 15 minutes after the pump test started and
after 7 hours of pumping, these samples along with samples
from the onsite pond were sent to New York Testing for
HENDERSON AND BODWELL CO~U,~'r, Nr- ,:.o,.E;.s
analysis. The Suffolk county Health Department secured
samples at I hour, 3 hours, and 6~ hour intervals after
pumping had started. The New York Testing analysis can be
found in Appendix C, while the Suffolk County Health
Department results can be found in Appendix D. In
comparing the test results there appears to be substantial
conformance between them. The only exception is the
detection of chloroform by New York Testing in both the
well samples and the pond sample. Although the level of
chloroform detected is below the allowable, a second
pumping test was performed and new samples were taken by
both Henderson and Bodwell and the Suffolk County Health
Department.
The second set of samples was taken to Ecotest Laboratories
(test results in Appendix E). Both their test results and
the Suffolk County Health Department's additional test
results, (test results in Appendix F), indicated no
detectable level of chloroform in the samples. Therefore,
it appears that the chloroform reported by New York Testing
was a laboratory problem and not a water quality problem.
SYSTEM DESCRIPTION AND OPERATIONAL GUIDELINES
Well Construction
The three production wells would each be about 54 feet
deep, located about 30 feet apart; each six inch diameter
well would be equipped with a submersible motor pump
capable of delivering 30 gpm at a dynamic head of between
40 and 60 feet, to be determined by the specific capacity
of the well.
6
HENDERSON AND BODWELL CO~UL~NGENGINEER$
The wells would be constructed and equipped in accordance
with New York State Standards.
Storage Required
An above ground storage tank of 54,000 gallon capacity is
proposed. This will provide sufficient storage to meet all
the peak demands. The tank would be of epoxy coated steel,
inside and out, meeting New York State Health Department
requirements, and would be 9 feet in depth and 32 feet in
diameter. (Approximate dimensions, subject to shop
drawings, etc.).
Well Pump Controls
The three well pumps will discharge into the above ground
54,000 gallon storage tank. They will be started and
stopped by 'Asco Tripoint" pressure switches of the
adjustable dead-band type. This type of switch is
exceedingly accurate and will be able to control the water
level in the 5~,000 gallon tank within a range of two or
three inches. One pump will be controlled to start when
the tank content is at 90% of capacity, and the second pump
to come on-line to supplement the first pump whenever less
than 66% of its capacity is contained in the 54,000 gallon
tank. The third well will act as a backup and come on line
in the event that one of the first two pumps fails to
operate.
This arrangement for controlling the pumping operations
from the wells will provide minimum disturbance of
hydraulic balance between fresh and salt water in the
strata beneath the well screens, as the wells will operate
HENDERSON AND BODWELL CONSULTING ENGINEERS
against a constant head and will not have a wide range of
pumping rates (such as they would have if they were pumpin9
directly to the hydropneumatic tank).
Service Pump Control
The 54,000 gallon tank will act as a clear well for two
service pumps~ each 125 gpm capacity when discharging
against a pressure of 6.0 pounds per square inch (psig).
Hydropneumatic Tank
These service pumps will discharge into a 3,000 gallon
nominal size hydropneumatic tank. The tank will be fitted
with the same type of PreSsure switch used for controlling
the well pump operations and arranged to control the
maximum pressure in the tank at 70 psi and the minimum
pressure at 35 psi. Normally, only one pump will be used
to feed this tank and the other will be a spare; but at any
time of high demand, when the one pump running cannot keep
the pressure above 35 psi, the second pump 'will come
on-line to aid it.
A small air compressor will be installed to maintain the
air-water balance in the hydropneumatic tank. From the
hydropneumatic tank, the water passes directly into the
small distribution system.
Chlorination
A small chemical feeder and associated equipment would be
furnished for disinfection, together with a complete spare
unit.
HENDERSON AND BODWELL CONSULTING ENGINEERS
Electrical tie-ins with the well pump control system would
start and stop the feeder When a well pump starts or stops.
It is expected to dilute 15% to 5% solutions
Hypochlorite for use as the disinfection agent.
of Sodium
Control
Control of pH will be provided by means of either sodium
hydroxide or sodium bicarbonate. Either compound would be
fed as a 4-5 percent solution, with the same equipment used
for either. Bicarbonate has the advantages of being safer
and self buffering (maximum pH about 8.3) in the event of
an overdose. Its major disadvantage is limited solubility
(6.5~ percent).
Stabilization
.Laboratory results obtained from the sampling at 60
gallons/minute indicate that iron may be found
intermittentl~ (present on January 7, 1986, absent on
January 22, 1986). Because of this, the Suffolk County
Department of Health Services has requested and it is
proposed that a chemical stabilization system be provided.
The method proposed is an additional drum/mixer/feeder
combination to be used for the addition of sodium
hexametaphosphate or other mutually acceptable stabilizing
agents.
Chemical Feeders - General
A total of six chemical feeders will be installed - two for
hypochlorite, two for alkali and two for polyphosphate.
All feeders will be the same size and a seventh will be
provided as a spare. When a well pump starts and runs, it
will start the operation of a set of feeders: one
HENDERSON AND BODWELL CONSULTIN§£NSlNEER$
hypochlorite, ~ne ~lkali, and one polyphosphate
The power circuits to the feeders will be tri~le
interlocked. In order for the feeders to run,. there will
have to b~ flow, pressure.and successful auxilllary contact
closure in the well pump motor starter. .Each. of t~ese
conditions will close a pair of contacts (wired In series) .
in the chemical feed pump motor circuit.
.
..
Although objectionable quantlti?s of pesticides or
fertilizers have not been found in the samples of w~ter
that have bee~ analyzed, the Department of Healt~ .Services
~alls attention to the presence of pesticides in
neighb?ring wells. They believe it possible that
objectionable chemical pollutants might be found in these
waters in the future. . . .
For that reason, space is provided in the plant d~slgn for
the installation of granular activated carbon filters' at
such time should they.become n~c~ssary. Space is provided

_
Distrlbution System . . .
The distribution__ system will consist of slx. inch mains.
No piping carrying potable water will be installed closer
than 10 feet to any piping carrying wastewater.
I~ 10
HENDERSON AND BODWELL CON~ULTiNS ENGINEER~
All piping is expected to be either rigid PVC pressure pipe
with ductile iron fittings or ductile iron pipe. PVC pipe
will conform with AWWA standard C900-81. Ductile iron pipe
fittings and joints respectively will conform with AWWA
standards C-151, C-150, C-110, and C-111, with cement
mortar lining in accordance with AWWA standard C-104.
Pipe will be installed in trenches at a depth of not less
than 4' 6".
Connectin~ Water Main
The water main connecting Angel Shores with the Cove will
be constructed of ductile iron pipe, thickness Class 52,
cement lined. Pipe will conform, with the iron pipe
specifications listed under "Distribution System".
The pipe will be eight (8) inches in diameter and will not
be connected to any fire hydrants.
Standby Power
The plant will be equipped with a standby generator of 40
KW capacity, sufficient to runn all machinery in the plant,
and one space heater. It is proposed to lock out the other
heater. Transfer of power'will be automatic. Fuel will be
L.P. gas or propane.
Summary
The water supply system described would furnish an adequate
supply of good quality water to the proposed residential
community. It would be essentially completely automatic in
operation and require a minimum of operational labor.
HENDERSON AND BODWELL CONSULTING ENOIN£ER$
Additional structural and operational details will be
furnished in the construction drawings and specifications
including, among other items, sterilization of tanks and
water mains, spare parts, chemical storage, chemical
testing equipment and supplies, etc.
An operating manual would also be provided.
