Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in March 2026. The violations listed here began between October 2025 and March 2026. By type: 5 monitoring, 5 monitoring and reporting and 2 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 7 as archived, 3 as unaddressed and 2 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
