Lead & copper sampling

Lead: latest 90th-percentile result 0 ppb — below the 10 ppb action level (sampled 2025-12-31, 1 result 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

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.

Where the water comes from

Groundwater.

Also holds emergency-only connections (Town of Surf City) — backup interconnections, not routine supply.

What the record doesn’t establish

  • Whether this system has PFAS — systems serving under 3,300 people generally weren't required to test.
  • 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.
