One thing here needs attention.
One thing 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 20,549 people in Cabarrus County.
This is not a violation today. EPA's PFAS limits take effect in 2029 (an extension to 2031 has been proposed).

Records can lag by up to a quarter, and they don't cover your home's own plumbing.

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; 5 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 City of Concord, whose recent record shows no unresolved health-based violations.
Buys water from Charlotte Water, whose recent record shows no unresolved health-based violations.
No health-based violations on record since 2021. Records can lag by up to a quarter, and they don't cover building plumbing.
Yes — 29 PFAS compounds under EPA's UCMR5 program, with 5 detected. PFOS measured up to 10.3 ppt, above the 4 ppt limit that takes effect in 2029. Samples are taken at entry points to the distribution system — treated water, not source water.
EPA records list about 20,549 people served in Cabarrus. 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.
