Excerpt from Water Well Standards: Del Norte County

Bulletin No. 7h-3, Recommended Minimum water well Construction and Sealing Standards for the Protection of Ground Water Quality, Del Norte County, gives the results of a comprehensive Ground water Quality Investigation conducted throughout Del Norte County. This is the final report incorporating the comments and recommendations of cooperating agencies and individuals on our preliminary edition of March l96h. The investigation was conducted under authority of Section 231 of the water code and at the request of interested agencies operating in the County.

This is one of a series of reports designed to formulate and recommend water well construction and sealing standards for particular localities of the State where regulation is deemed necessary for the protection of ground water quality. In Del Norte County, where no such regulation exists, many water wells which have been improperly con structed or abandoned are contributing to quality impairment of ground water. The report concludes that water well construction and sealing standards should be adopted and enforced. The recommended standards presented are based on geologic, hydrologic, and water quality condi tions and well construction practices found in Del Norte County. These standards are similar to and should supplement the minimum standards presented in Bulletin No. 7h entitled, Recommended Minimum Well Con struction and Sealing Standards for the Protection of Ground Water Quality, State of California.

The report recommends adoption of water well construction and sealing standards in Del Norte County. The report also recommends continuation of investigational work by the local agencies, leading to the identification and correction of existing improperly constructed and abandoned water wells.
