Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2026. The violations listed here began between April 2025 and February 2026. By type: 7 monitoring and reporting and 5 public notice, recordkeeping or other. The contaminant or rule involved most often is Public Notice (5 of them). EPA lists 6 as resolved and 6 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.
