Does Rapid River Water & Sewer Dist have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in February 2013. The violations listed here began between January 1993 and February 2013. By type: 9 monitoring and reporting, 2 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 7 as archived and 5 as resolved.
