North and South Basin groundwater cleanup projects

The Orange County Water District implements a proactive groundwater monitoring and surface water program to protect the quality of the Orange County Groundwater Basin, which supplies 85% of the drinking water for 2.5 million people in north and central Orange County. Water provided by OCWD meets or exceeds state and federal drinking water standards.

Industrial chemicals have impacted an area in the North Basin (near Fullerton, Anaheim, Placentia and Buena Park) and the South Basin (near Santa Ana, Tustin and Irvine) of the Orange County Groundwater Basin. OCWD is proactively seeking ways to clean up the pollution in a united effort with local and national regulatory agencies.

OCWD is committed to working with the community to solve threats to groundwater. Together, we can ensure a clean and reliable water supply, protect ratepayers and protect long-term property values. Information including presentations, reports, studies, press releases, and other related data will be updated regularly on this website.To submit questions or comments, please Contact Us.
