Water Quality Reports

PFOA/PFOS

June 2019 - Garden Grove is one of several local agencies that received a Monitoring Order from the California State Water Resources Control Board (SWRCB) Division of Drinking Water (DDW), requiring testing for per- and polyfluoroalkyl substances (PFAS) in six of our drinking water supply wells.

While the PFOA and/or PFOS levels require local governing body notification, they are below state and response level for drinking water use. At this time, we will continue to provide service to our customers and closely monitor PFOA, PFOS, and other water-quality measurements to ensure the health and safety of our customers. There are several factors that led us to this decision, with safety and water quality as the top considerations. The City of Garden Grove is consistently working to reduce these levels in our water supply.
