Does Echo Glen Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2025. The violations listed here began between January 2020 and February 2025. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Revised Total Coliform Rule, Nitrate, trans-1,2-Dichloroethylene and Tetrachloroethylene. EPA lists 10 as archived and 2 as resolved.
