Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in May 2025. The violations listed here began between June 1980 and May 2025. By type: 8 monitoring and reporting, 2 public notice, recordkeeping or other, 1 reporting and 1 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (2 of them). EPA lists 10 as resolved and 2 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.
