Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in October 2025. The violations listed here began between January 2019 and October 2025.

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.
