Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in April 2025. The violations listed here began between October 2016 and April 2025. By type: 6 contaminant level above the legal limit, 4 monitoring and reporting, 1 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (10 of them). EPA lists 7 as archived, 4 as resolved and 1 as addressed. 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.

Addressed means the violation is not resolved or archived and is covered by formal enforcement.
