PFAS detected

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

Contaminant	Max	Detection rate	Period
Pfpea	0.0040 µg/L	2/8	2023
PFBS	0.0037 µg/L	1/8	2023
PFOA	0.0057 µg/L	1/8	2023

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.

Contaminant	Level vs EPA limit	Detection rate	Source	Period
Copper	115 µg/L 8.8% of the EPA limit 1300 µg/L worst single sample: 1337 µg/L	131/182	SYR4	2013–2019
TTHM	57.795 µg/L 72% of the EPA limit 80 µg/L worst single sample: 90.9 µg/L	100/100	SYR4	2013–2019
Total Haloacetic Acids (HAA5)	60.82 µg/L 101% of the EPA limit, at the 95th percentile of samples — 60 µg/L worst single sample: 76 µg/L	100/100	SYR4	2013–2019
Lead	0.0 mg/L 0% of the EPA limit 0.0150 mg/L	15/15	LCR	2024
