No health-based violations reported to EPA in the five years to October 2026, like 83% of the 3,525 systems serving 10,001–50,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2022–Dec 2024, was 3.0 ppb, below the 15 ppb action level that applied. That’s higher than 79% of similar systems’ latest results.
