Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in January 2023. The violations listed here began between January 2004 and January 2023. By type: 9 contaminant level above the legal limit and 3 monitoring and reporting. The contaminant or rule involved most often is Nitrate (10 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. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
