EPA's records list 11 violations for this system; none is health-based, and the most recent began in June 2023. The violations listed here began between January 1994 and June 2023. By type: 9 monitoring and reporting, 1 reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 8 as resolved and 3 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.
