Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in March 2026. The violations listed here began between December 2024 and March 2026.

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.
