What's in KANNAPOLIS's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving KANNAPOLIS.
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.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 46.6 ppb, 776x above the EWG health guideline of 0.06 ppb.
Perfluorohexane sulfonate (PFHXS) significantly above health guideline
Moderate concernPerfluorohexane sulfonate (PFHXS) detected at 0.6 ppt, 600x above the EWG health guideline of 0.001 ppt.
Haloacetic acids (HAA5) significantly above health guideline
Moderate concernHaloacetic acids (HAA5) detected at 37.2 ppb, 372x above the EWG health guideline of 0.1 ppb.
