Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2026. The violations listed here began between November 2024 and February 2026. By type: 8 monitoring, 3 reporting and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (11 of them). EPA lists 8 as archived and 4 as resolved.
