class to construct a well or wells.
The form provided by the NJDEP that depicts the construction
details of a well, which is completed by the well driller subsequent
to well permit issuance and well installation.
A.
Purpose and intent. The objective
of the water quality evaluation is to assess if the proposed water
supply sources for a development or commercial establishment meet
NJDEP drinking water quality MCLs. In the event that one or more constituents
do not meet the applicable MCLs, standard treatment systems need to
be readily available.
B.
Groundwater quality determination.
(1)
Groundwater quality will
be determined for the pumping well and on-site observation wells as
part of this program. Groundwater samples from the pumping well, used
for the aquifer pumping test, will be collected during the pumping
phase of that test.
(2)
The water samples from the
on-site observation wells can be collected either three days in advance
or three days after the pumping test has been completed. The samples
must be collected in accordance with the NJDEP Field Procedures Manual.
At a minimum, the samples shall be analyzed by an NJDEP-certified
laboratory for hardness, gross alpha particle activity, arsenic, iron,
manganese, copper, lead, nitrate, and total and fecal coliform bacteria.
The samples shall also be analyzed for volatile organic compounds
for which the United States Environmental Protection Agency or NJDEP
has determined maximum contaminant levels using USEPA Method 524.2.
(3)
During the pumping test,
field measurements of pH, conductivity/total dissolved solids and
temperature shall be made with calibrated instruments.
(4)
If site conditions or the
site history indicate the potential historic use of materials containing
heavy metals, pesticides, herbicides, or other volatile or semi-volatile
organic compounds at or near the site, these analyses must also be
conducted.
(5)
Based on past historical
operations at the site or at nearby properties, the Board, at its
discretion, may require additional analyses of the groundwater to
assess current and potential future impacts. The results of the water
sample analyses will be used to assess background (pre-development)
water quality conditions.
A hydrogeologic report must be submitted with each application
for subdivision of two or more lots and all site plans. This report
shall document the design and implementation of the aquifer test and
include the following data, information and analysis:

Calculations of aquifer characteristics
such as transmissivity and storage coefficient, calculations of the
cone of depression, potential impacts to adjacent well owners, and
an evaluation of the long-term sustained yield for the wells.
B.
All water-level measurements
obtained during the three phases of the aquifer test in electronic
format acceptable to the Township.
C.
A detailed hydrogeologic description
of the aquifers encountered beneath the site and adjacent properties.
D.
A detailed evaluation of the
water supply demand for an average and peak day. This demand should
be supported with information on anticipated population, expected
unit density, size of units, lawn and garden irrigation needs, pool
filling requirements, and other anticipated water uses.
E.
An inventory of all wells within
1,000 feet of the proposed subdivision/site plan boundaries appended
and placed on a base map of the site area. This inventory must be
submitted in electronic format acceptable to the Township.
F.
Figures depicting site geology,
topography, surface water bodies, water level elevations, groundwater
flow, and development plans.
G.
All laboratory water quality
sampling data tabulated and summarized. One copy of the laboratory
reports is necessary for filing with the Township.
H.
A detailed evaluation of potential
impacts from subsurface sewage disposal systems on groundwater quality.
A site plan depicting topography, actual and planned well locations,
septic leach field locations, and fracture trace locations at a minimum
scale of one inch equals 200 feet should be included. For any and
all locations where a fracture or set of fractures intersects one
or more wells and/or septic leach fields, a detailed assessment of
treatment technologies should be included. The treatment technologies
should provide adequate assurances that any and all groundwater pumped
from the wells will satisfy federal and New Jersey drinking water
standards (MCLs) and will not be degraded by the septic leach field
discharges.
I.
The hydrogeologic report shall
be prepared and signed by a qualified hydrogeologist using applicable
sections of GSR 29 or successor document as a guide.
J.
The hydrogeologic report shall
include the name and license number of the well driller and pump installer.
The report shall include the names of the persons and firm responsible
for collecting the water level measurements. In addition, the report
shall include copies of the completed NJDEP well records.
A.
Precipitation. A test conducted
during a period in which 0.5 inch or more of precipitation is recorded
at or near the site must be repeated or technical documentation provided
that the precipitation event had no impact on water levels 24 hours
before, during, and 24 hours after the test.
B.
Background phase. Antecedent
influences must be determined and, if necessary, water level data
from the pumping phase and recovery phase must be corrected. Insufficient
data to assess these influences will require repetition of all three
phases of the aquifer test.
C.
Pumping phase.
(1)
If the pumping rate does
not exceed the average daily demand by 120% or the peak day demand
cannot be pumped within a twenty-four-hour period, the aquifer beneath
the site may be deemed insufficient to meet the proposed demands and
the applicant may need to review and adjust the site demand and development
units. Some alternatives include:
(a)
Repeating the pumping
test with two or more pumping wells to achieve average or twenty-four-hour
peak day demand for a development. This may be particularly applicable
for large developments in low-yielding bedrock aquifer systems.
(b)
Decreasing the number
of developed lots.
(c)
Rearranging the lot configuration.
(2)
If the pumping rate varies
by more than 10% of the average flow rate, the entire test shall be
repeated.
(3)
If the pump shuts down during
the pumping phase, the entire test must be repeated.
(4)
If water levels in the pumping
and/or observation wells exceed the measurement capacity of the devices
used for measuring changes in water levels and measurements are not
recorded with other devices in accordance with the schedule listed
in Table A-1, the test must be repeated.
(5)
If the pumping data indicate a change in aquifer transmissivity as a result of fracture dewatering, all analyses of the potential radius of influence and impacts to neighbors, streams, and wetlands must be conducted using the lower value of aquifer transmissivity. If this lower aquifer transmissivity indicates that the anticipated demand cannot be supported by the aquifer beneath the site, the applicant will need to review and adjust the site demand and development units as outlined in Subsection C(1) above.
D.
Recovery phase.
(1)
For purposes of evaluating
water level recovery, the recovery phase duration will be equal to
the pumping phase duration. For example, if the pumping phase is eight
hours in duration, water levels eight hours after the pump has been
turned off will be compared to the pre-pumping static water level
to assess recovery magnitude and degree of recovery.
(2)
If water level recovery is less than 90% of full recovery at the end of a recovery phase of similar duration as the pumping phase, the applicant must show through standard/recognized aquifer test analytical methods and calculations that the well or wells are capable of full recovery. If full recovery cannot be shown or groundwater mining/dewatering has occurred, the applicant will need to review and adjust the site demands and development units as outlined in Subsection C(1).
E.
Neighboring well.
(1)
If the drawdown is measured
or projected to be more than one foot at any existing adjacent property
well or along the subdivision boundary, the applicant's hydrogeologist
must evaluate long-term potential impacts to adjacent properties based
on the actual operating condition of wells in that zone or along that
portion of the subdivision/site plan boundary.
(2)
If a drawdown of five feet
or more (this may be adjusted by a Township hydrogeologist and should
take lot sizes into account) is noted in any existing adjacent property
well, or is projected at any property boundary, then the aquifer will
be deemed to have insufficient transmissivity and capacity to support
the proposed subdivision/site plan. The applicant will need to review
the site demand, development units, and well locations to ensure that
drawdown will not exceed five feet at any site boundaries.
F.
Impacts to streams and wetlands.
If drawdown is measured or projected to induce leakage from streams
or wetlands such that base flow in these streams will be directly
reduced or wetlands partially or entirely dewatered, then the demand
and development units must be reduced to prevent adverse impacts to
stream flow and wetlands.
G.
Additional testing. Any test
that must be repeated, restarted, or re-conducted at a reduced demand
must satisfy all the requirements of this article, including but not
limited to renotification of all property owners within 500 feet and
resubmission of an aquifer test plan for Board approval prior to implementation
of the test.
A.
The first test phase will involve
the collection of background water levels prior to the start of the
test. The second test phase will involve the pumping of water from
the well and the monitoring of water level drawdown in the observation
and pumping wells. The third test phase will involve the measurement
of water level recovery in the observation and pumping wells after
the pump has been shut down. This third phase of the test must, at
a minimum, be the same length as the pumping phase.
B.
The aquifer test (all three phases)
shall not be conducted during a precipitation event or events in which
total precipitation equals or exceeds 0.5 inch. Precipitation must
be recorded with a National Weather Service acceptable rain gauge
on site during all phases of testing, and measurements for each day
must be included in the hydrogeologic report. If precipitation occurs
during the test, the applicant shall provide precipitation amounts
and sufficient data to show that the precipitation did not recharge
the aquifer during the test and impair the test results. If precipitation
amounts exceeding 0.5 inch are recorded, the test may have to be repeated.
C.
The pumping equipment must be
installed in the pumping well at least 24 hours prior to the start
of the background phase.
D.
Prior to starting the background
phase, water levels in the test well and observation wells must be
permitted to stabilize for a minimum of three days after all drilling
activities are completed.
E.
During the background phase,
water levels should be collected at a minimum of one measurement per
hour for the twenty-four-hour period prior to the start of the pumping
test. It is the applicant's responsibility to collect sufficient data
to determine background conditions and to ensure that antecedent influences
can be fully characterized. Barometric measurements and additional
water level measurements can be made by the applicant to evaluate
the change in water levels resulting from barometric pressure changes
and/or influences from off-site pumping.
F.
On the day of the pumping phase,
water levels shall be collected from the pumping and observation wells
to determine static water level conditions prior to the start of pumping.
Water levels in wells on neighboring properties should be allowed
to stabilize to at or near static prior to the start of pumping. For
any observation well which has been pumped within the 24 hours preceding
the test, two depth-to-water measurements, at least one hour apart,
shall be collected to assess if the well has fully recovered prior
to the start of pumping.
G.
When the aquifer test is started,
the pumping flow rate shall be adjusted, within the first several
minutes of pumping, to a uniform (constant) pumping rate as required
for a constant-rate test and in accordance with the approved aquifer
test plan. The flow rate shall not vary by more than 10% throughout
the test. If the flow rate fluctuates more than 10%, the test may
be deemed invalid and the applicant will be required to repeat the
notification and testing process.
H.
Water level measurements during
the pumping phase of the test shall be collected in accordance with
Table A-1. This same schedule shall be followed for the recovery phase
of testing upon shutdown of the pump in the test well.

I.
Aquifer pumping test rate and
duration. The rate and duration of the aquifer test will depend upon
the size of the proposed development and expected average and peak
daily demands for water.
(1)
The average daily and average
yearly water demand for human consumption within the subdivision or
site plan must be determined according to the guidelines in N.J.A.C.
7:10-12.6. Demand calculations must include irrigation systems, if
proposed, and water usage for filling of swimming pools and all other
demands. The peak day demand is twice the average daily demand. For
nonresidential developments, peak day demand must include seasonal
factors.
(2)
The pumping phase must simulate
peak day demand and, therefore, the pumping phase duration is not
to extend more than 24 hours. The minimum pumping rate is calculated
by dividing the peak day demand by 1,440 minutes per twenty-four-hour
period. If the well yield is sufficient, shorter pumping periods can
be used, but should be no less than eight hours in duration.
(3)
If the demand exceeds 100,000
gallons per day, a New Jersey water allocation permit must be obtained
from the New Jersey Department of Environmental Protection.
(4)
For mixed developments containing
both residential and nonresidential properties, each portion will
be tested separately. Wells installed for the residential portion
must be used as observation wells for the nonresidential testing and
wells installed for nonresidential use must be used as observation
wells for the residential testing.
(5)
The pumping rate will be
determined by equipping the discharge pipe with a calibrated flow
meter to measure flow rate and determine total volume pumped from
the well.
(6)
The discharge shall be directed
so that it leaves the site without infiltrating to the aquifer. The
pumped water discharge location must be at least 200 feet from the
pumping well. Any and all permits required by the NJDEP and/or local
authorities for the discharge of pumped water must be obtained prior
to starting the test.
A.
The number of observation wells
required per aquifer test will depend on the number of dwelling units
and/or commercial water demand. New and existing observation wells
may be located such that they can be used as future water supply wells
but they shall be located in such a manner that will yield the most
accurate information concerning the aquifer.
B.
Observation wells should be completed
to similar depths as the pumping well.
C.
Observation wells must be located
parallel and perpendicular to strike of the primary regional fractures
and those intersected by the tested well. Additional observation wells
should be located to evaluate potential secondary fractures and impacts
to adjacent properties.
D.
A fracture trace analysis showing
the location and orientation of fracture lineaments must be included
with the aquifer test plan. This same analysis with additional information
regarding septic system locations must be included in the final hydrogeologic
report. The fracture trace analysis must be used to identify all observation
wells on the site and to identify neighboring property owners' wells
to be monitored during the test.
E.
All wells must be located in
accordance with the minimum distances required by N.J.A.C. 7:10 12.12.
F.
One observation well should be
located within 200 feet of the test well and at least one observation
well should be located along a fracture trace or preferential fracture
direction between 200 and 500 feet from the pumping well.
G.
For residential developments
of two new residential units or more, the number of observation wells
shall be as shown in Table B-1.
H.
For nonresidential developments
with anticipated daily demands exceeding 800 gallons per day, the
number of observation wells shall be as shown in Table B-2.
I.
The observation wells and the
pumping well must have a geologic log describing the depth and types
of soils and rocks encountered and the depth and yields of all water-bearing
fracture zones. The logs must include static water level measurements
and total yield estimates for each well.

decide to participate and to have their existing wells monitored,
only three must be monitored.
(3)
However, if any of the property
owners requesting monitoring have wells completed to a depth less
than 100 feet, these wells must also be monitored in addition to three
other wells.
(4)
A map depicting the location
of all wells to be monitored and a list of all property owners within
500 feet of the subdivision boundary that requested monitoring is
to be submitted to the Board's hydrogeologist for review and approval
prior to implementing the test.
(5)
The observation wells on
neighboring properties should be selected to assess whether water
level drawdown impacts from the pumping well will extend beyond the
subdivision boundary in any direction.
[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. II)]
(6)
The Board reserves the right
to retain a qualified hydrogeologist to review the proposed monitoring
locations and to make recommendations to revise the locations to be
monitored.
Sample notices shall follow the form as recommended and approved
by the Township Planning Board. An application package containing
the recommended form shall be kept on file in the Planning Board office.
