Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between July 2024 and January 2026. By type: 9 monitoring, 1 public notice, recordkeeping or other, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (9 of them). EPA lists 9 as archived and 3 as unaddressed.
