PFAS Contamination Detected

PFAS ("forever chemicals") have been reported in samples from water systems associated with ZIP code 54435. One or more compound results are above the level of a federal PFAS MCL with compliance required from 2029.

Detected compounds: PFOA, PFPeA, PFBA, PFHxA, PFHpA.

Highest measured level: 0.021 µg/L

Reverse osmosis (RO) and activated carbon block filters can reduce PFAS at the tap. Certifications list the compounds covered: an NSF/ANSI 53 or 58 claim for PFOA/PFOS does not cover every PFAS, so check that the product lists the compounds detected here.
