Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in July 2025. The violations listed here began between July 2014 and July 2025. By type: 8 monitoring and reporting, 2 contaminant level above the legal limit, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Chlorite (4 of them).
