Of the 12 most recent violations in EPA's records, 8 are health-based, and the most recent began in January 2026. The violations listed here began between July 2022 and January 2026.

The contaminant or rule involved most often is Total trihalomethanes (TTHM) (8 of them). EPA lists 7 as archived and 5 as resolved.
