What's in SOUTHPORT (T)'s tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving SOUTHPORT (T).
PFAS contamination
Severe concernPerfluorooctanoic acid (PFOA), Perfluorooctane sulfonate (PFOS) detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.

Moderate concernHaloacetic acids (HAA9) detected at 23.4 ppb, 390x above the EWG health guideline of 0.06 ppb.
Total trihalomethanes (TTHMs) significantly above health guideline
Moderate concernTotal trihalomethanes (TTHMs) detected at 49.3 ppb, 329x above the EWG health guideline of 0.15 ppb.
Haloacetic acids (HAA5) significantly above health guideline
Moderate concernHaloacetic acids (HAA5) detected at 22.4 ppb, 224x above the EWG health guideline of 0.1 ppb.
