92103.04 - Special groundwater protection.

The enforcement agency may designate areas where potable groundwater quality is known to exist and where a well will penetrate more than one aquifer. The enforcement agency may require in these designated areas special well seals to prevent mixing of water from several aquifers. Where an applicant proposes well construction, reconstruction, alteration, repair or construction work, in such an area, the enforcement agency may require the applicant to provide a report prepared by a registered geologist or a registered civil engineer that identifies all strata containing poor quality water and recommends the location and specification of seal or seals needed to prevent entrance of poor quality water or its mitigation into other aquifers.

The enforcement agency may take such other action as it determines reasonably necessary to protect the degradation of both quantity and quality of any known aquifer resulting from the installation, modification, refurbishing, construction, repair or destruction of well or from improper well operations, maintenance, and/or from excessive pumping capacity.
