What's in LITCHFIELD PARK's tap water
Top water quality concerns identified by the EPA and Environmental Working Group across the utility serving LITCHFIELD PARK.
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 6.93 ppt, 6929x above the EWG health guideline of 0.001 ppt.
Arsenic significantly above health guideline
Moderate concernArsenic detected at 6.09 ppb, 1522x above the EWG health guideline of 0.004 ppb.
Chromium (hexavalent) significantly above health guideline
Moderate concernChromium (hexavalent) detected at 9.83 ppb, 491x above the EWG health guideline of 0.02 ppb.
