BE IT ORDAINED by the Township
Committee of the Township of Wantage that a new Chapter 15A of the Revised
General Ordinances of the Township of Wantage being the entitled “The
Aquifer Protection and Well Testing Chapter” shall be adopted as
follows:
Section 1. A new Chapter 15A shall be added
as follows:
CHAPTER XV-A
AQUIFER PROTECTION AND WELL TESTING
15A-1.1 Purpose
This aquifer protection and well testing ordinance is adopted to ensure
the adequacy of potable groundwater supply for residential and commercial
development in areas not served by public water supply and to ensure that
such water is safe for human consumption and use. Abandoned and faulty
wells may cause pollutants to reach the aquifer, creating risk to life
safety of residents drawing water from that source. These provisions are
established to promote the health, safety and welfare of the citizens
of the Township of Wantage. These provisions do not excuse any person
or entity from complying with all other relevant requirements and obligations
imposed by State and federal laws and regulations and other local ordinance
provisions.
15A-1.2 General Provisions
a. A plot plan with locations of all existing
wells must be submitted with all development applications. Every reasonable
effort, including records search and field investigations, must be employed
to locate existing wells. The assistance of a licensed well driller should
be sought when subsurface wells (where well casing does not come above
ground surface) are probable (e.g., old farmsteads, abandoned houses,
foundations). If there are no existing wells, a letter from the applicant’s
engineer so stating must be submitted. A field inspection may be required.
b. A “statement of intent” as to which
wells, if any, are to remain in use and which wells are to be abandoned
must be submitted to the Township for each development project. Well
status must also be designated on the plot plan referred to in section
15A-1.2(a) above.
c. All existing wells which do not meet New Jersey
Department of Environmental Protection (“NJDEP”) Standards
for the Construction of Public Noncommunity and Nonpublic Water Systems
set forth in N.J.A.C. 7:10-12, et seq. must be brought up to those standards
or certified sealed by a licensed well driller prior to site improvements.
Temporary exception can be made for wells in use and existing wells,
which will be used as monitor wells during pumping tests. Requests for
a temporary exception must be made to the Township Engineer.
d. All wells which are to be abandoned in accordance
with Section 15A-1.2(b) must also be sealed and certified by a licensed
well driller prior to site alteration or improvements and aquifer well
testing.
e. Joint patterns should be taken into consideration
when locating wells and septic systems. Because vertical joints are
abundant, every reasonable effort shall be made to ensure that wells
and septic systems are not located along the same joint line, and to
maximize separation.
f. A wellhead protection area may be reserved as open
space on the up-gradient side of the cluster of domestic wells in a
subdivision. Location and size of the wellhead protection areas for
each subdivision will be determined on a case-by-case basis.
15A-1.3 Aquifer Testing for Commercial/Industrial/Multi-Family
Residential Development
a. Projected water demand of the project must
be determined in accordance with NJDEP Standards for the Construction
of Public Noncommunity and Nonpublic Water Systems set forth at N.J.A.C.
7:10-12, et seq.
b. If the project water demand is 100,000 gallons per
day (gpd) or more, the applicant must obtain a water diversion permit
from the NDJEP. Pumping tests must be in accordance with NJGS GSR 29,
“Guidelines for Preparing Hydrogeologic Reports for Water-Allocation
Permit Applications”. A copy of the permit application must be submitted
to the Township for review.
c. If the projected water demand is less than 100,000
gpd but greater than or equal to 50,000 gpd, at least two observation
wells are required in accordance with the testing procedure set forth
at Section 15A-1.3(b) above. One observation well should be located along
structure, and one across structure from the test/production well. Existing
wells, on and off site, may be used as observation wells with the property
owner’s permission. Any owner of an existing well within 500 feet
or the zone of influence, whichever is greater of the test/production
well may request monitoring of that well as an observation well at the
applicant’s expense. Locating and accessing the well shall be at
the observation well owner’s risk and expense. The owner of the
observation well shall sign a release holding the well tester harmless
for any inconvenience. The observation well should be sampled for coliform
before and after the pumping test. The applicant is required to chlorinate
and resample any observation well contaminated with coliform during testing.
d. If the project water demand is greater than 3,000
gpd but less than 50,000 gpd, one test/production well and one observation
well shall be required. An existing well may be used as the monitoring
well subject to the conditions stipulated in Section 15A-1.3(c) above.
Any owner of an existing well within 500 feet or the zone of influence,
whichever is greater, of the test/production well may request monitoring
of that well at the applicant’s expense, and subject to the conditions
provided in Section 15A-1.3(c) above. An aquifer pumping test of 24 hours
followed immediately by a standard recovery test must be conducted on
the test/production well. Discharge must be metered. Draw down during
the pumping test must be monitored in the pumping and monitor wells.
e. For any test conducted under Section 15A-1.3 hereof,
water samples shall be collected near the end of the pumping test and
analyzed for the following:
pH
Hardness
Fe
Mn
Nitrate
Chloride
Coliform bacteria
VO scan
Pesticides
Herbicides
Additional tests as required by the Private Well Testing Act of 2002,
N.J.S.A. 58:12A-26, et seq., shall also be completed. The pumping rate
and total gallons pumped should demonstrate that the needed water is available
without detrimental impact on the aquifer or nearby wells.
The test/production well site shall be chosen by the applicant’s
hydrogeologist to maximize yield and minimize interference with other
wells. The hydrogeologist shall be responsible for the design and supervision
of the pumping test.
f. A geologic and hydrogeologic report containing appropriate
maps, well logs, pumping test data, information on nearby wells, onsite
water balance, results of the water analyses, discussion of the adequacy
of the water supply and local/regional effects on the water table, and
recommendations must be prepared by the applicant’s hydrogeologist
and submitted to the Township for review.
g. The report described in Section 15A-1.3(f) above shall
be reviewed by the Township Engineer who may require additional testing
or information.
h. Monies to cover all review expenses must be deposited in an escrow
account prior to preliminary site plan approval in accordance with the
requirements of N.J.S.A. 40:55D-53.1, et seq.
15A-1.4 Aquifer Testing for Single-Family Residential
Developments
For all major subdivisions, an aquifer test and hydrogeologic report shall
be submitted and reviewed prior to granting of preliminary subdivision
approval. Aquifer testing and data to be included in the report are as
follows:
a. The average daily, peak day, and average
yearly water demand for each subdivision of 4 or more lots must be determined
according to guidelines set forth at N.J.A.C. 7:10-12.7; peak day is twice
the average daily demand.
b. The minimum number of test wells required is based
on the number of lots, and the acreage of the tract to be developed as
follows:
Number of lots |
Wells |
4-10 |
2 test wells, 1 pumping test |
11-25 |
3 test wells, 1 pumping test |
26-50 |
4 test wells, 1 pumping test |
>50 |
4 test wells plus one additional test well for each additional
25 lots or part thereof; at least 4 test wells per 100 acres. More
wells may be needed depending on geology and well yield; one pumping
test per each 50 lots or part thereof. |
Each pumping well must have an observation well within 500 feet. More
pumping tests than indicated above may be needed to pump the estimated
water demand of a project in a 24-hour period, depending on the yield
of the test wells.
c. Wells should be located by applicant’s hydrogeologist
on lots in such a manner that they may become the domestic supply for
that lot. Locations should take into consideration:
- area distribution of test wells on the tract;
- geologic variability beneath the site;
- topography;
- geologic structures, joints, faults, etc.; and
- 5. two wells in each group should be located on adjacent proposed
lots and along the dominant joint direction. One of these wells should
be the pump-tested well in each group.
Wells must be constructed in accordance with Standards for the Construction
of Public Noncommunity and Nonpublic Water Systems set forth at NJDEP
N.J.A.C. 7:10-12, et seq.. Each test well must have a locking cap.
d. Pumping Test(s).
1. The pumping test(s) shall be designed by the applicant’s
hydrogeologist to pump at least the average daily water demand and preferably
the peak day demand at the highest rate possible. For 50 or more lots,
the peak day demand plus 20% additional must be pumped.
2. The pumping test(s) must last at least 4 hours and up to 24 hours.
Test(s) must be conducted in accordance with standard methods. All test
wells shall be monitored for drawdown by reliable methods; dip tubes
should be installed for this purpose in a pumping well. Discharge must
be metered and channeled away from the wellhead. The pumping test must
be followed immediately by a standard recovery test to 90% recovery
in the pumping well. If the water level has not recovered to 90% in
one hour, a water level should at least be taken the following morning
to be sure that the level has recovered to 90% of static.
3. The pumping rate, total gallons pumped, amount of drawdown and recovery
rate should demonstrate that the needed water is available without detrimental
impact on the aquifer or nearby wells.
e. Water samples must be collected near the end of the
pumping test(s) and be analyzed as per Section 15A-1.3(e) above, or as
required by the Township Engineer. Projects of 50 or more lots must comply
with Public Community Water Supply testing standards.
f. A geologic and hydrogeologic report containing appropriate
maps, well logs, pumping test data, information on nearby wells, onsite
water balance, results of the water analyses, discussion of the adequacy
of the water supply and local/regional effects on the water table, and
recommendations must be prepared by the applicant’s hydrogeologist
and submitted to the Township Engineer for review. For developments of
50 or more lots, the hydrogeologic report must also be reviewed by NJDEP.
g. The report required in Section 15A-1.4(f) above shall
be reviewed by the Township Engineer who may require additional testing
or information.
h. Monies to cover all review expenses must be deposited in an escrow
account prior to preliminary site plan approval in accordance with the
requirements of N.J.S.A. 40:55D-53.1, et seq.
15A-1.5 Individual Well Testing
1. Any new well constructed in the Township must have an approved water
supply yielding at least two (2) gallons per minute for the proposed dwelling
size before a building permit can be issued.
Section 2. Should any section, paragraph,
sentence, clause or phrase of this Ordinance be declared unconstitutional
or invalid for any reason by any Court of competent jurisdiction, such
provision(s) shall be deemed severable and the remaining portions of this
Ordinance shall remain in full force and effect.
Section 3. All ordinances or parts of ordinances
or resolutions that are inconsistent with the provisions of this Ordinance
are repealed to the extent of such inconsistency.
Section 4. The Township Clerk is directed
to give notice at least ten days prior to the hearing on the adoption
of this ordinance to the County Planning Board and to all others entitled
pursuant to the provisions of N.J.S.A. 40:55D-15. Upon the adoption of
this ordinance, after public hearing, the Township Clerk is further directed
to publish notice of the passage and to file a copy of this ordinance,
as finally adopted, with the Sussex County Planning Board, as required
by N.J.S.A. 40:55D-16.
Section 5. This ordinance shall take effect
after publication and passage according to law.
