What the records flag
Needs attention
PFOS measured at 19 ppt — above the 4 ppt limit systems must meet by 2029
This is not a violation today. EPA's PFAS limits take effect in 2029 (an extension to 2031 has been proposed).
PFOA
11 ppt (limit 4)
PFOS

Lead & copper sampling
Lead: latest 90th-percentile result 3 ppb — below the 10 ppb action level (sampled 2025-12-31, 11 results in the 10-year window).
The 90th-percentile result means 9 out of 10 sampled homes were at or below this level. It measures the water system's corrosion control — it cannot tell you whether your own home's plumbing adds lead. Results older than 10 years, future-dated compliance periods, and physically implausible values are excluded.
PFAS testing
29 PFAS compounds tested under EPA's UCMR5 program; 2 detected.
PFOA: up to 11 ppt — above the 4 ppt limit systems must meet by 2029.
PFOS: up to 19 ppt — above the 4 ppt limit systems must meet by 2029.
UCMR5 sampling (2023–2026) at entry points to the distribution system. 'Not detected' means below the reporting limit (~4 ppt for PFOA/PFOS), not zero. A result above a future MCL is not a violation today — compliance deadlines are 2029 (2031 extension proposed). These results describe treated water leaving the plant — not the river or lake this system draws from.
Where the water comes from
Surface water. No purchased-water records on file.
What the record doesn’t establish
Whether your home's own plumbing adds lead or copper — no dataset covers indoor pipes.
