Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2025. The violations listed here began between October 2000 and December 2025. By type: 6 monitoring and reporting, 3 monitoring and 3 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 8 as resolved, 2 as unaddressed and 2 as archived.
