123 community water systems tested

8.1%
of tested systems detected PFOA or PFOS
(10/123)

PFAS — “forever chemicals” — are synthetic compounds that accumulate in the body and are linked to cancer, liver damage and immune effects. In 2024 the EPA set enforceable limits of 4 parts per trillion each for PFOA and PFOS. These are the only nationwide PFAS measurements, from the EPA’s UCMR-5 program.

Water systems

PFAS value per system, 2023–2025. EPA limit — 4 ppt (0.004 µg/L) for PFOA and PFOS, set in 2024. Systems that detected PFOA or PFOS are highlighted and listed first. “Not detected” means the contaminant was measured but not found.
