Does Hanna City have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in December 1999. The violations listed here began between July 1987 and December 1999. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 12 as archived. 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.
