To protect against or abate salt water encroachment or
deterioration of the water quality of the ground water, the Division shall take
into consideration the best information on the geologic and hydrologic
characteristics of the rocks and the ground water withdrawals of the area
involved and shall require the user to take such action as it deems necessary
for control of brackish or salt water intrusion into fresh water aquifers. The
control measures may include, but not be limited to, the following:
(a) pumping arrangements to reduce ground
water withdrawal in areas of concentrated pumping;
(b) rearrangement of the location of wells to
eliminate or reduce concentrated areas of ground water withdrawals;
(c) requirement of selective withdrawal from
other available fresh water aquifers than presently used;
(d) curtailment of ground water withdrawal of
proposed water users in the area;
(e) selective curtailment or reduction of
ground water withdrawal where it is found to be in the public interest or
general welfare to protect the water resources;
(f) conjunctive use of fresh water or
brackish water or salt water aquifers, or waters of less desirable quality
where water quality of a specific character is not essential;
(g) use of observation or monitoring wells,
drilled into fresh water aquifers between areas of ground water withdrawal and
the seacoast, to detect the inward movement of salt water or to detect the
deterioration of water quality;
(h)
use of interceptor wells, drilled into the area of encroachment, to the
intercept the brackish or salt water moving toward the center of excessive
ground water withdrawal;
(i) use of
relief wells, drilled into the brackish or salt water aquifer, to relieve
hydraulic pressure in the aquifer causing encroachment;
(j) plugging with cement of deep wells that
have penetrated brackish or salt water zones or zones of undesirable quality
water, where hydraulic pressure cause leakage and contaminate fresh water
aquifers of lower pressures;
(k)
abandonment of wells, which are then to be filled, plugged and sealed; and
(l) Such other control or
abatement techniques as are technically feasible and proven to be successful in
other areas and nationally.
