City of Rockingham: drinking water record

Three 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 12,510 people in Richmond County.

What the records flag

Needs attention

This system buys water from HAMLET WATER SYSTEM, which has 11 unresolved health-based violations

Purchased water is treated by the seller before it arrives, so the seller's compliance record travels with the water it sells.

Needs attention

PFOS measured at 4.9 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).

Lead & copper sampling

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.

PFAS testing

29 PFAS compounds tested under EPA's UCMR5 program; 5 detected.

  • PFOS: up to 4.9 ppt — above the 4 ppt limit systems must meet by 2029.
  • PFOA: up to 4.4 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.

Buys water from Hamlet Water System — which has 11 unresolved health-based violations on record. Purchased water is treated by the seller, so the seller's record travels with it.

Buys water from Richmond County Water System, whose recent record shows no unresolved health-based violations.

What the record doesn’t establish

  • Whether your home's own plumbing adds lead or copper — no dataset covers indoor pipes.

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.
