EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in October 2024. The violations listed here began between April 1994 and October 2024.

The contaminant or rule involved most often is Lead and Copper Rule Revisions (2 of them). EPA lists 4 as resolved, 2 as unaddressed, 1 as addressed and 1 as archived. 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.

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