PFAS in ZIP Codes This System Serves

PFAS ("forever chemicals") have been reported in samples from water systems associated with the ZIP codes in this system's area. These results can come from other water systems serving the same ZIP codes; check the UCMR5 section for any results reported for this system. 3 detections recorded.

State PFAS values in our reference data (state action level (not an enforceable limit)); check current state rules: PFOA: 10 ppt, PFOS: 10 ppt
Health concern: Exposure to certain PFAS has been associated with some cancers and with immune and developmental effects; effects differ by compound. Many PFAS break down very slowly in the environment.
Recommended filter: An activated carbon filter certified under NSF/ANSI 53 or a reverse osmosis system certified under NSF/ANSI 58 for the PFAS listed in its certification. Find the right filter โ†’
