Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in January 2026. The violations listed here began between August 2023 and January 2026. By type: 10 contaminant level above the legal limit, 1 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Asbestos (10 of them).
