Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in July 2025. The violations listed here began between June 1979 and July 2025. By type: 8 monitoring and reporting, 2 public notice, recordkeeping or other and 2 contaminant level above the legal limit.
