EPA's records list 11 violations for this system; 6 are health-based, and the most recent began in January 2023. The violations listed here began between April 2002 and January 2023. By type: 6 contaminant level above the legal limit and 5 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 8 as resolved, 2 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.
