§ 33.0636 General Location of Water Wells.

It shall be unlawful for any person or entity to drill, dig, excavate, or bore any water well at any location where sources of pollution or contamination are known to exist, existed, or otherwise substantial risk exists that water from that location may become contaminated or polluted even though the well may be properly constructed and maintained. Every well shall be located an adequate distance from all potential sources of contamination and pollution as follows:

Sewers 50 ft. minimum
Septic tank, sewage holding tank, subsurface sewage leach lines or leach fields 100 ft. minimum
Cesspool or seepage pit 150 ft. minimum
Animal or fowl confined 100 ft. minimum
Any subsurface sewage disposal system discharging 5,000 gal./day or more 200 ft. minimum

Minimum distances from other sources of pollution or contamination shall be determined by DEHS upon investigation and analyses of the probable risks involved.

Where particularly adverse or special hazards are involved, the foregoing distances shall be increased or special approved means of protection, particularly in the construction of the well, shall be provided as determined by DEHS.
