What's in MENASHA's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving MENASHA.
PFAS contamination
Severe concernPerfluorooctanoic acid (PFOA), Total PFOS and PFOA detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 22.0 ppb, 367x above the EWG health guideline of 0.06 ppb.
Total PFOS and PFOA significantly above health guideline
Moderate concernTotal PFOS and PFOA detected at 2.23 ppt, 318x above the EWG health guideline of 0.007 ppt.
Total trihalomethanes (TTHMs) significantly above health guideline
Moderate concernTotal trihalomethanes (TTHMs) detected at 32.5 ppb, 216x above the EWG health guideline of 0.15 ppb.
Recommended filters for MENASHA
Filters matched to the specific contaminants in MENASHA's water supply.
Reverse Osmosis or NSF P473 certified carbon
$80-$750Activated carbon and RO are the only technologies proven to remove PFAS at certified levels.
Carbon block (NSF/ANSI 42 + 53)
$40-$750Activated carbon is highly effective for disinfection byproducts like TTHM and HAA5.
