Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2025. The violations listed here began between January 2022 and January 2025.

The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 11 as resolved and 1 as archived. 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.
