Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2024. The violations listed here began between January 2003 and January 2024. By type: 8 monitoring and reporting, 3 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 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.
