Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in July 2016. The violations listed here began between June 1979 and July 2016. By type: 9 contaminant level above the legal limit, 2 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (10 of them). EPA lists 9 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.
