In response to community concerns, Sweetwater Authority recently announced the detection of a small amount of PFAS (per- and polyfluoroalkyl substances) in treated water from the Sweetwater Reservoir.
The detected concentration was below levels that would necessitate mitigation measures, meaning additional water treatment is not required. However, regulatory guidelines mandate notification to customers about such findings.
PFAS are complex chemical compounds widely found in everyday products, including non-stick cookware, water-resistant clothing, and food packaging. Their pervasive presence has posed challenges for water providers worldwide, prompting efforts to monitor and reduce these substances in distribution systems.
Sweetwater Authority assured the public that its water is entirely safe for consumption and meets all current federal and state regulations. To maintain transparency and ensure continued safety, the agency plans to conduct quarterly tests over the next year to monitor PFAS levels in treated water.
To keep the community informed, Sweetwater Authority has added resources to its website, offering detailed information about PFAS and their impact on water quality. Customers can also direct inquiries via email at PFAS@sweetwater.org or by calling (619) 409-6786.
