Health-based violations
Separately from PFAS, EPA records 16 health-based violations across 5 of the county’s water systems since 2020, the most recent in 2025. They involved E. coli, trihalomethanes, haloacetic acids, nitrate.
What this means
PFAS are industrial chemicals that EPA describes as breaking down only very slowly in the environment. In April 2024 EPA set the first enforceable national limits: 4 ng/L for PFOA and PFOS, 10 ng/L for PFHxS, PFNA and GenX.
These figures are county-level and come from EPA’s sampling of public water systems. They describe the worst result found in the county, not what comes out of any particular tap — that depends on which system serves the address, and on the plumbing in the building. A private well is not covered by this programme at all.

This is a county-level reading from federal monitoring. What comes out of your own tap depends on your system — and on your home.
