Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in March 2025. The violations listed here began between October 1999 and March 2025.

The contaminant or rule involved most often is Consumer Confidence Rule (5 of them). EPA lists 8 as resolved, 3 as archived and 1 as unaddressed. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.

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