Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in May 2021. The violations listed here began between May 1998 and May 2021. By type: 5 monitoring, 5 contaminant level above the legal limit and 2 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 9 as resolved and 3 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.
