No health-based violations reported to EPA in the five years to October 2026, like 78% of the 7,966 systems serving 1,001–3,300 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2022–Dec 2024, was 7.0 ppb, below the 15 ppb action level that applied. That’s higher than 96% of similar systems’ latest results.
