PFAS detected

PFAS are industrial “forever chemicals”. These are the EPA's latest nationwide test results (2023–2025).

Contaminant	Max	Detection rate	Period
Hfpo-Da	0.0097 µg/L	8/8	2025
Pfhxa	0.0053 µg/L	8/8	2025
PFOS	0.0079 µg/L	8/8	2025
Pfpea	0.0059 µg/L	8/8	2025
PFOA	0.0061 µg/L	7/8	2025
PFBS	0.0041 µg/L	4/8	2025

Other contaminants detected

Each bar shows the measured level as a share of the EPA limit: green is well under, amber is close to it, red is over. For lead and copper the limit applies to exactly the 90th-percentile figure shown, so red there means a real exceedance. For everything else the limit applies to a running annual average while the figure is the 95th percentile of this system's samples — over 100% is worth reading, but is not by itself a violation. Where a single sample came in higher than that percentile, it is noted under the bar. Formal violations are listed separately.
