Local California certified laboratories

Irvine Ranch Water District tests its water regularly to monitor and ensure the quality of the water throughout our distribution system. But when it comes to testing water at individual homes and businesses, customers should reach out to a California certified laboratory for assistance.

For more information, visit the California Department of Social Services webpage.
