Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2025. The violations listed here began between January 2024 and January 2025. By type: 9 monitoring and reporting and 3 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 10 as archived and 2 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
