What's in KENOSHA's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving KENOSHA.
PFAS contamination
Severe concernPerfluorononanoic acid (PFNA), Perfluorooctanoic acid (PFOA) detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.
Total PFOS and PFOA significantly above health guideline
Moderate concernTotal PFOS and PFOA detected at 3.65 ppt, 521x above the EWG health guideline of 0.007 ppt.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 23.0 ppb, 383x above the EWG health guideline of 0.06 ppb.
Perfluorohexane sulfonate (PFHXS) significantly above health guideline
Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 0.255 ppt, 255x above the EWG health guideline of 0.001 ppt.

Recommended filters for KENOSHA
Filters matched to the specific contaminants in KENOSHA's water supply.
Filter certified for PFOA/PFOS (NSF/ANSI 53 or 58)
$180-$750Reverse osmosis and some carbon block filters reduce PFAS. Look for certification to NSF/ANSI 53 or 58 for PFOA/PFOS.
Carbon filter certified for VOCs (NSF/ANSI 53)
$180-$599Activated carbon is effective for disinfection byproducts. Look for NSF/ANSI 53 VOC reduction.
