Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 2018. The violations listed here began between April 1991 and October 2018. By type: 5 monitoring and reporting, 3 public notice, recordkeeping or other, 2 contaminant level above the legal limit, 1 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 7 as archived and 5 as resolved.

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.
