Quick actions for Woodbury residents
Top concerns in this water
Based on the most recent EPA and EWG data, these are the most significant water quality issues for 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.
