Water Quality

Water quality is a top priority for Calleguas Municipal Water District. Calleguas delivers water which meets or exceeds all federal and state water quality standards; this is accomplished by a rigorous water quality program. The cornerstones of the water quality program are the certified laboratory program, the drinking water program, lake monitoring program, and the Salinity Management Pipeline program. Staff coordinate with local regulators and water purveyors to ensure compliance with existing and new regulations as the landscape of water quality compliance changes.
