Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in September 2025. The violations listed here began between September 2012 and September 2025. By type: 10 monitoring and reporting, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is E. coli (6 of them). EPA lists 6 as unaddressed, 5 as resolved and 1 as archived. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
