Please find attached recommendations for edits to the current California Well Standards Bulletins. The California Conference of Directors of Environmental Health (CCDEH) is an association of California Environmental Health Directors. Our association’s Well Technical Advisory Committee drafted the recommendations over the last year as part of a collaborative effort of technical experts from local jurisdictions and representatives from the California Ground Water Association (CGA). The attachments also incorporate recommendations preparedby a prior Well Technical Advisory Committee group between July 2010 and August 2013. There are some areas noted that need further technical review, particularly as it relates to the use of Bentonite.
