OCWD is first public lab in California to achieve PFAS detection certification

Orange County Water District’s (OCWD; the District) Philip L. Anthony Water Quality Laboratory is the first public agency laboratory in California to achieve state certification to analyze for per- and polyfluoralkly substances (PFAS) in drinking water by Environmental Protection Agency (EPA) Method 533. Certification was granted by the Environmental Laboratory Accreditation Program (ELAP) administered by the State Water Resources Control Board.

The lab previously became the first public agency lab to receive ELAP certification for PFAS analysis via EPA Method 537. Together, these certifications enable the lab to analyze 29 PFAS targets in drinking water.
