Does Riverside Sd Chattaroy Elementary have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in June 2019. The violations listed here began between January 2008 and June 2019. By type: 10 monitoring and reporting and 2 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (2 of them). EPA lists 10 as archived and 2 as resolved.
