[ARCHIVED] Yorba Linda Water Providers Give Update on PFOA and PFOS Testing

Water Providers Give Update on PFOA and PFOS

Yorba Linda residents’ water needs are served by two entities, Golden State Water Company and the Yorba Linda Water District.

In compliance with guidance from the State Water Resources Control Board’s Division of Drinking Water (DDW), Golden State Water Company recently completed additional water quality testing at certain groundwater production wells in the Placentia-Yorba Linda System. The new testing requirements are for detecting very low concentrations (measured in parts per trillion) of unregulated drinking water contaminants.

This week, Golden State Water mailed letters to customers informing them that recent tests of groundwater extracted by two GSW wells supplying the Placentia-Yorba Linda system have detected the presence of Perflurooctanoic Acid (PFOA) and Perfluorooctanesulfonic Acid (PFOS). Golden State Water has proactively taken the wells out of service. Golden State Water has elected to take these steps to ensure customers can rest assured regarding the quality of their water. Although customer notification is not required, GSW is taking steps to proactively inform customers and to maintain full transparency with regards to water quality.

The Placentia-Yorba Linda system provides drinking water to customers in Placentia portions of Anaheim, and Yorba Linda. The water delivered to customers in these communities has and continues to meet all quality and safety standards, which are established to protect public health.


These substances have also been found at low levels in the Yorba Linda Water District's water supply. Rest assured, YLWD water is safe and reliable; it meets all drinking water standards. 

YLWD is building a treatment plant that will have the ability to remove PFOA and PFAS contaminants. While the plant is being built, the district will purchase water that the Metropolitan Water District of Southern California imports from Northern California and the Colorado River.
