Two things here need 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 25,212 people in Johnston County.
Purchased water is treated by the seller before it arrives, so the seller's compliance record travels with the water it sells.

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, 3 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; 8 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 Kenly — which has 6 unresolved health-based violations on record. Purchased water is treated by the seller, so the seller's record travels with it.
Buys water from Sampson Co WTR Dist Ii, whose recent record shows no unresolved health-based violations.
Buys water from Wayne Water Districts — which has 1 unresolved health-based violation on record. Purchased water is treated by the seller, so the seller's record travels with it.
Buys water from Wilson Co Southwest Water Dist, whose recent record shows no unresolved health-based violations.
Also holds emergency-only connections (Fork Township Sanitary District) — backup interconnections, not routine supply.
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 8 detected. PFOA measured up to 7.7 ppt, above the 4 ppt limit that takes effect in 2029; PFOS measured up to 9.7 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 25,212 people served in Johnston. 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.
