Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in December 2025. The violations listed here began between January 1986 and December 2025. By type: 7 monitoring and reporting, 2 required treatment not met, 2 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is E. coli (2 of them). EPA lists 7 as resolved, 3 as archived and 2 as unaddressed. 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
