The Orange County Water District (OCWD; the District) strives to deliver clean, reliable drinking water to 2.5 million customers every day. OCWD and the water agencies in its service area are committed to operating in compliance with all state and federal and guidelines and regulatory requirements.
Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are chemicals that are prevalent in the environment and were once commonly used in many consumer products. Through an ongoing investigation, California and many other states have found that PFAS have made their way into our groundwater due to releases from a number of sources, including airports and fire training centers associated with the use of firefighting foam, and industrial facilities where PFAS is used in the manufacturing process.
PFAS have been detected in the Orange County Groundwater Basin. OCWD provides regular PFAS updates to community stakeholders to inform them of the proactive measures that the District and retail water agencies have take to address PFAS in the Basin.
