North Carolina · water system · PWSID NC0467046
One thing here needs attention.
Two things 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 3,500 people in Onslow County.
Purchased water is treated by the seller before it arrives, so the seller's compliance record travels with the water it sells.

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.
No UCMR5 results on file for this system. Systems serving under 3,300 people generally weren't required to test — this is absence of testing, not absence of PFAS.
Groundwater.
Buys water from Onslow WTR and Sewer Authority — which has 1 unresolved health-based violation on record. Purchased water is treated by the seller, so the seller's record travels with it.
No health-based violations on record since 2021. Records can lag by up to a quarter, and they don't cover building plumbing.
No UCMR5 results are on file for this system — absence of testing, not absence of PFAS.
EPA records list about 3,500 people served in Onslow. 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.
