Of the 12 most recent violations in EPA's records, 8 are health-based, and the most recent began in January 2026. The violations listed here began between May 2024 and January 2026. By type: 8 contaminant level above the legal limit, 3 public notice, recordkeeping or other and 1 monitoring and reporting. The contaminant or rule involved most often is Arsenic (6 of them).
