Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in January 2013. The violations listed here began between August 2006 and January 2013. By type: 5 required treatment not met, 4 contaminant level above the legal limit and 3 monitoring and reporting. The contaminant or rule involved most often is Surface Water Treatment Rule (5 of them). EPA lists 11 as resolved 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. 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.
