Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in April 2024. The violations listed here began between January 1996 and April 2024. By type: 8 monitoring and reporting and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them).
