Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in January 2026. The violations listed here began between April 1998 and January 2026. By type: 6 required treatment not met, 5 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Surface Water Treatment Rule (6 of them).
