EPA's records list 11 violations for this system; 1 is health-based, and the most recent began in July 2025. The violations listed here began between January 1991 and July 2025. By type: 6 monitoring and reporting, 4 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 7 as archived, 3 as resolved and 1 as unaddressed. 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.

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