Permits are required for the construction and/or abandonment of all water wells including, but not limited to driven wells, monitoring wells, cathodic wells, extraction wells, agricultural wells and community water supply wells. The wells are inspected during different stages of construction to help verify standards are being met. All drinking water wells are evaluated once they complete installation to ensure they comply with State well standards and meet minimum drinking water standards. If found in compliance, the homeowner is issued a clearance letter authorizing their use. In addition, bacterial and chemical sampling of water can be provided upon request.
Local Primacy Agency (LPA)
This program has been delegated primacy from the State to provide regulatory oversight and inspect at various frequencies all public water systems in the County that have between 15 and 199 service connections and those serving restaurants, schools and industry. Currently this program permits about 200 systems of these types.
This program also currently provides limited regulatory oversight to those water systems serving between 5 and 14 service connections. Inspections are conducted on each system annually. There are currently about 100 water systems of this size.
In January 2017, the State Water Resources Control Board (State Board), Division of Drinking Water (DDW) sent out a summary of Senate Bill 1263 (SB 1263), effective January 1, 2017. Click here for more information on how this impacts water systems.
