Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2024. The violations listed here began between October 2018 and January 2024. By type: 11 monitoring and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (11 of them). EPA lists 11 as resolved and 1 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.
