The Standards for Construction of Public Non-Community and Nonpublic
Water Systems, (N.J.A.C. 7:10-12.1, et seq.) is hereby adopted in
its entirety as part of this chapter as if set forth at length herein.
Whenever any standard or requirement of N.J.A.C. 7:10-12.1, et seq.,
is referred to in this chapter, the most recent edition shall be deemed
to be incorporated herein by reference, notwithstanding the fact that
such edition may have been published subsequent to enactment of this
chapter. The provisions of N.J.A.C. 7:10-12.1, et seq., however, shall
be modified as follows:
|
1.
|
The following definitions are added to N.J.A.C. 7:10-12.3:
|
|
AQUIFER CONTRIBUTION — shall mean the portion of the well
flow at any given time which comes directly from the aquifer.
| |
|
AQUIFER CONTRIBUTION RATE — shall mean the rate at which
water flows from the aquifer to the well, established by the constant
head pumping rate.
| |
|
AQUIFER CONTRIBUTION VOLUME — shall mean the volume of
water which comes from the aquifer during the shortfall time. Aquifer
contribution volume is shortfall time x aquifer contribution rate.
| |
|
ASSURED TIME — shall mean the time it will take to pump
the assured volume out of the well at the peak demand rate.
Assured time = assured volume\peak demand rate
| |
|
ASSURED VOLUME — shall mean the volume of water in a well
between the static level and the constant head level. Assured volume
is constant head drawdown x well storage capacity.
| |
|
CONSTANT HEAD — shall mean a stable water level attained
under equilibrium pumping conditions which is attained when the water
level in a well changes at a rate of less than 0.5 feet (six inches)
per hour of pumping at a constant rate.
| |
|
CONSTANT HEAD DRAWDOWN — shall mean the drawdown in a
well when a constant head condition has been obtained. Constant head
drawdown is measured from the static level.
| |
|
CONSTANT HEAD LEVEL — shall mean the water level in a
well under constant head conditions.
| |
|
CONSTANT HEAD PUMPING RATE — shall mean a pumping rate
at which a constant head is attained in a constant head test.
| |
|
CONSTANT HEAD TEST — shall mean a pumping test conducted
upon the well so that drawdown remains constant with time. For the
purpose of this chapter, a rate of less than 0.5 feet (six inches)
per hour is considered constant.
| |
|
DRAWDOWN — shall mean the decline in the water level in
a well during pumping, measured from the static or freestanding water
level which existed prior to pumping.
| |
|
HYDROPNEUMATIC TANK — shall mean a water tank installed
in a household water supply system to maintain pressure in that system.
It is only secondarily a water supply tank.
| |
|
PEAK DEMAND RATE — shall mean the average rate of discharge
of water from a well, in gallons per minute, during peak demand periods.
The peak demand rate equals the number of bathrooms in the residence
multiplied by three g.p.m.
| |
|
PEAK DEMAND TEST — shall mean a pumping test conducted
upon a well to evaluate its capability to supply peak demand needs.
The test is conducted at a rate and a duration equal to or greater
than the peak demand rate and peak time.
| |
|
PEAK LOAD — shall mean the volume of water, in gallons,
required during each peak demand period. Peak load is equal to the
number of bedrooms in the residence multiplied by 100 gallons.
| |
|
PEAK TIME — shall mean the duration of time, in minutes,
during which the peak demand rate is exerted on a well by a home.
Peak time is computed in the following manner:
Peak time = 100 gallons x number of bedrooms\3 g.p.m. x number
of bathrooms
| |
|
SHORTFALL TIME — shall mean the time needed to pump the
shortfall volume out of the well at the peak demand pumping rate.
Shortfall time is Peak time - Assured time.
| |
|
SHORTFALL VOLUME — shall mean the volume of water needed
to supplement the assured volume in order to make up the peak load.
Shortfall volume = Peak load - Assured volume.
| |
|
STATIC LEVEL — shall mean the water level in the well
either before or after pumping when all drilling and pumping effects
on the aquifer have dissipated and the well is in equilibrium with
atmospheric pressure.
| |
|
STORAGE CONTRIBUTION — shall mean the proportion of the
well flow at any given time which comes from the storage in the well.
| |
|
WELL FLOW — shall mean the flow rate of water expressed
in gallons per minute (g.p.m.) from a well at any given time. It is
the sum of the aquifer contribution and the storage contribution.
| |
|
WELL STORAGE — shall mean the volume of water within the
well which is available for pumping.
| |
|
2.
|
N.J.A.C. 7:10-12.4, General provisions and prohibitions, shall
be amended to add the following testing and construction requirements:
|
a.
Applicability of Testing Requirements. The testing requirements contained
in this section shall be applicable to new wells or single-family
dwellings or cottages that:
1.
Are to be located in a geological region designated in the Montgomery
Township Natural Resources, Inventory (1984) Geology and Groundwater
Map as "Lockatong Argillite" or "Diabase;" or
2.
Are to be located in a geological region designated in the Montgomery
Township Natural Resources Inventory (1984) Geology and Groundwater
Map as "Stockton Sandstone" or "Brunswick Shale;" and (i) have a yield
of less than five gallons per minute (5 g.p.m.) as determined by a
well driller licensed under the laws of the State of New Jersey or
(ii) are in an area where it has been demonstrated by the performance
of existing wells that water supply capabilities in the immediate
area are limited.
b.
Test Requirements. The capability of a well to meet the peak demand
and the total daily demand of a household shall be evaluated through
a two-part pump test. The first part of the pump test, known as the
"peak demand test" is described in subparagraph c, below. The second
part of the pump test, known as the "constant head test" is described
in paragraph d below. The tests shall be conducted for each new well
to which this section, as noted in paragraph a above, is applicable.
The tests shall be conducted by a well driller licensed under the
laws of the State of New Jersey who shall certify the results of the
tests to the Administrative Authority based on the utilization of
the worksheet forms contained in Appendix A of this Code and on calculations
made through the use of Appendix B of this Code. (Appendices A and
B may be found at the end of this subsection[1] BH4-1.2) A minimum of 72 hours' advance notice of the
tests, excluding Saturdays, Sundays and legal holidays, shall be provided
to the agent of the Administrative Authority making the observation.
[1]
Appendix A and B are included as attachments to this chapter.
c.
Peak Demand Test. The peak demand test is a standard drawdown pump
test used to determine whether the well can supply the water needed
by the household during times of peak water demand. In the test the
well is pumped at the peak demand rate estimated for the household
for a time equal to or greater than the estimated peak demand time.
The results of the peak demand test must demonstrate that well flow
during peak time plus well storage will equal or be greater than peak
load of the well or the test results will be deemed "unsatisfactory."
This requirement is expressed by the following equation:
Well Flow x Peak Time + Well Storage = Peak Load
If the results of the peak demand test are "unsatisfactory,"
the well shall be modified or abandoned as set forth in paragraph
e below. Relocation of the well may be considered.
d.
Constant Head Test. The constant head test determines whether or
not flow from the aquifer to the well can replenish water removed
from the well during peak demand periods. Immediately following completion
of the peak demand test, a constant head test shall be conducted for
the purpose of measuring aquifer contribution to the well. Such measurement
shall be attained by adjusting the pumping rate to the constant head
pumping rate. The constant head pumping rate should be equal to or
as close as possible to the peak demand rate. Once achieved, the constant
head pumping rate shall be noted and expressed in gallons per day.
For one, two and three bedroom homes the constant head pumping rate
shall equal or exceed 720 gallons per day or be deemed "unsatisfactory."
For dwellings having more than three bedrooms, the constant head pumping
rate shall equal or exceed the figures noted below or be deemed unsatisfactory:
|
Number of Bedrooms
|
Minimum Required Constant Head Pumping Rate
|
|---|---|
|
4
|
800 g.p.d.
|
|
5
|
1,000 g.p.d.
|
|
6
|
1,200 g.p.d.
|
|
7
|
1,400 g.p.d.
|
e.
Unsatisfactory Results.
1.
Satisfactory Demand Test/Unsatisfactory Constant Head Test - where
the results of the peak demand test are satisfactory but those of
the constant head test unsatisfactory, the well shall be deepened
or developed so as to produce a larger aquifer contribution. The well
shall be fully retested in accordance with paragraphs b, c and d above.
If the results of the tests continue to be unsatisfactory, the well
shall be modified and retested until satisfactory test results are
achieved or abandoned and sealed in accordance with applicable State
regulations.
2.
Unsatisfactory Peak Demand Test/Satisfactory Constant Head Test -
where the results of the peak demand test are unsatisfactory and those
of the constant head test are satisfactory, additional water storage
shall be provided through the deepening of the well:
(a)
The amount of additional storage required shall be determined
by subtracting the aquifer contribution volume from the shortfall
volume and dividing that amount by the storage capacity of the well.
This requirement is expressed by the following equations:
|
Required Well Depth = static water level + constant head drawdown
+ 10 feet (drawdown safety factor) + additional well drawdown + 10
feet (pump clearance factor)
|
|
WHERE
|
|
Constant Head Drawdown = (Appendix A, Step F-18)
|
|
AND WHERE
|
|
Additional Well Drawdown = Additional
|
|
Well Storage Volume
|
|
Well Storage Capacity
|
|
AND WHERE
|
|
Additional Well Storage = Shortfall Volume - Aquifer Volume
Contribution Volume
|
(b)
When additional well storage is provided either by deepening
the well, the well shall be fully retested in accordance with paragraphs
b and c above and shall not be approved until satisfactory test results
are obtained. If the results of the test continue to be unsatisfactory,
the well shall be abandoned and sealed in accordance with applicable
State regulations and relocation may be considered.
3.
Unsatisfactory Peak Demand Test/Unsatisfactory Constant Head Test
- where the results of both required tests are unsatisfactory, the
well shall be deepened or developed to increase water flow to the
well. The well shall be fully retested in accordance with paragraphs
b, c and d above. If the results of the test continue to be unsatisfactory,
the well shall be modified and retested until satisfactory test results
are achieved or abandoned and sealed in accordance with applicable
State regulations and relocation may be considered.
f.
Well Approved Prior to Septic System Construction. All new wells
for single-family dwellings or cottages located in either the Lockatong
Argillite or Diabase Regions shall be drilled and certified for approval
in accordance with all applicable provisions of this Code prior to
issuance of any permits relating to construction of individual or
community subsurface sewage disposal systems required by the Board
of Health.
g.
Minimum Pump Size. The minimum permissible pump size for single-family
dwellings and cottages shall be sized to have the ability to deliver
the peak demand rate to the plumbing fixtures at the highest elevation
in the dwelling or cottage.
h.
Permanent Air-line System. All wells which are to be evaluated through
a two-part pump test in accordance with the requirements of this chapter
shall be equipped with a permanent air-line system, installed by the
well driller with the permanent pump as a means for measuring the
position of the water level in the well. The air-line system requires
the installation of a small diameter copper pipe or plastic tube (the
air line) from the top of the well to the final pumping level point
in a well. A pressure gauge fitted with an air pump connection fitting
shall be affixed to the top of the airline outside the pitless adaptor
so that the gauge and air pump connection fitting are permanently
accessible. The depth of the air line in the well is to be permanently
recorded on or near the air pressure gauge.
i.
Blasting Prohibited. Blasting through the use of dynamite or other
explosives shall not be permitted in the construction of wells.
j.
Certified Test Results. In addition to any water quality tests required
under N.J.A.C. 7:10, the certified tests results of any peak demand
and constant head tests as may be required by this Code shall accompany
an application for certification.
|
3.
|
N.J.A.C. 7:10-12.12, Minimum distance requirements, shall be
amended to add the following:
|
|
The placement of the pump shall be no less than 10 feet below
the depth the water measured at the end of a successful peak demand
pump test and no deeper than 10 feet above the bottom of the well.
|
