What's in Woodbury's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving Woodbury.
PFAS contamination
Severe concernPerfluorooctane sulfonate (PFOS), Perfluorooctanoic acid (PFOA) detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.
Perfluorohexane sulfonate (PFHXS) significantly above health guideline
Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 1.92 ppt, 1915x above the EWG health guideline of 0.001 ppt.
Perfluorooctanoic acid (PFOA) significantly above health guideline
Moderate concernPerfluorooctanoic acid (PFOA) detected at 10.0 ppt, 112x above the EWG health guideline of 0.09 ppt.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 3.43 ppb, 57x above the EWG health guideline of 0.06 ppb.

Recommended filters for Woodbury
Filters matched to the specific contaminants in Woodbury'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.
