Does Seven Mile Water & Sewer District have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in June 2011. The violations listed here began between January 1993 and June 2011. By type: 11 monitoring and reporting and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 of them). EPA lists 7 as archived and 5 as resolved. 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.
