Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in September 2025. The violations listed here began between July 2023 and September 2025.

The contaminant or rule involved most often is Public Notice (5 of them). EPA lists 10 as resolved, 1 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.
