It draws ground water influenced by surface water and serves 1,298 people in all.
1 health-based violation reported to EPA in the five years to October 2026: a lead and copper treatment requirement (Lead and Copper Rule Revisions), beginning Oct 2024. 78% of the 7,966 systems serving 1,001–3,300 people had none. 1 older violation is still open, since 2024: a lead and copper treatment requirement (Lead and Copper Rule Revisions), per EPA’s records.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2018–Dec 2020, was 0.0 ppb, below the 15 ppb action level that applied. It’s from 2020: EPA has no newer result for this system. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
