40B-3.512. Well Construction Requirements  


Effective on Tuesday, June 22, 1999
  • 1(1) In the construction of a well, reasonable caution shall be taken to maintain the premises in sanitary condition and to minimize the entrance of contaminants into the water resource. Water and materials used in construction shall be reasonably free of contamination.

    43(2) For wells which penetrate multiple aquifers or zones, the well shall be completed so as to prevent cross-contamination of different aquifers or zones if significantly different water quality exists between these aquifers or zones, and to prevent leakage of water from one aquifer or zone to another aquifer or zone.

    94(3) For wells completed into unconsolidated aquifers, casing shall extend from land surface to the well screen. The well screen shall be attached to the casing with a watertight seal.

    124(4) For wells obtaining water from consolidated aquifers, a continuous casing shall extend from land surface into the top of the producing aquifer, provided however, that the bottom end of the well casing must extend to or below the static water level of the aquifer intended to supply the water to the well. In addition, all caving zones below the uppermost consolidated unit shall be cased.
