Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2025. The violations listed here began between April 2023 and October 2025. By type: 12 monitoring and reporting. The contaminant or rule involved most often is Gross alpha (excluding radon and uranium) (2 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.
