Does North 16 Domestic Water Assn have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in September 2006. The violations listed here began between January 2002 and September 2006. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminants or rules involved are Total coliform bacteria (TCR), Beryllium, Cyanide and Barium. 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.
