Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2023. The violations listed here began between September 1992 and January 2023.

The contaminant or rule involved most often is Consumer Confidence Rule (5 of them). EPA lists 6 as archived, 5 as resolved and 1 as unaddressed.

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