The Water Quality Section is responsible for administering and carrying out the Water Quality, Cross Connections Control, and Flushing Programs. Staff is responsible for keeping current with all new State and Federal mandated water quality regulations and integrating any new requirements into the existing procedures. This section insures that Garden Grove’s water meets all applicable State and Federal water quality standards, is protected from possible cross connections, contamination and pollution.
Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are chemicals that are prevalent in the environment and were once commonly used in many consumer products. They are part of a larger group referred to as per-and polyfluoroalkyl substances (PFAS). Due to the prolonged use of PFOA and PFOS, the chemicals are now being detected in water sources throughout the United States.
Last year, Garden Grove was 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 PFAS in drinking water supply wells. While the wells tested below state and Response Levels (RLs) for drinking water use at that time, the City continued to monitor and consistently work to further reduce the PFAS levels.
Recently, the state lowered RLs for PFOA and PFOS that resulted in a number of water agencies voluntarily removing groundwater wells from service, including six wells from Garden Grove. This, and any other immediate actions needed to maintain the safety and quality of our drinking water, will result in increased reliance on costlier imported water until we find other ways to meet our community’s long-term water demands, such as implementing new water treatment systems.
The City is focused on continuing its efforts to provide safe and high-quality water to more than 32,000 Garden Grove water customers. We will continue to closely monitor PFOA and PFOS levels, and keep the community informed of any potential issues or concerns.
