Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in August 2025. The violations listed here began between October 2010 and August 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.
