Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in January 2026. The violations listed here began between July 2016 and January 2026. By type: 5 public notice, recordkeeping or other, 4 monitoring and reporting and 3 required treatment not met. The contaminant or rule involved most often is Consumer Confidence Rule (3 of them). EPA lists 8 as resolved, 3 as archived and 1 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.
