North Carolina · water system · PWSID NC0197020
One thing here needs attention.
One more thing is worth knowing, and one could not be determined from the record.
What EPA and state records show about this community water system — compliance, PFAS testing, lead sampling, and where its water comes from. Serving about 12,573 people in Wilkes County.
A health-based violation means a contaminant limit or a required treatment step wasn't met.

Most PFAS compounds tested have no federal drinking-water limit — detection is not the same as exceeding a standard.

Lead: latest 90th-percentile result 0 ppb — below the 10 ppb action level (sampled 2025-12-31, 4 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.
29 PFAS compounds tested under EPA's UCMR5 program; 1 detected.
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.
Surface water.
Buys water from Town of North Wilkesboro, whose recent record shows no unresolved health-based violations.

EPA compliance records list 1 health-based violation since 2021, 1 without a recorded resolution. Administrative (paperwork) records are counted separately and never added in.
Yes — 29 PFAS compounds under EPA's UCMR5 program, with 1 detected. Samples are taken at entry points to the distribution system — treated water, not source water.
EPA records list about 12,573 people served in Wilkes. Service-area boundaries have known errors — a water bill is the ground truth for any single address.

Records lag their agencies' refresh cycles — a recent change may not appear yet. Absence from a dataset is absence of a record, never evidence that water is clean.
