Well Permitting Agencies

In California, regulatory authority over well construction, alteration, and destruction activities rests with local jurisdictions (cities, counties, or water agencies), who have the authority to adopt a local well ordinance that meets or exceeds DWR Well Standards.  If no local well ordinance has been adopted, the state's Model Well Ordinance takes effect in that jurisdiction. Permitting and enforcement are carried out by the local enforcing agency (LEA), such as the County Department of Environmental Health. LEAs are listed below alphabetically by county; cities and water agencies are listed under the counties they reside in. Please help us keep this list up to date.
