A copper mine operating under state discharge and aquifer-protection permits found that water leaving one of its tunnels carried elevated traces of selenium and copper after groundwater infiltration pushed the outlet past surface-water-quality standards. CEI led a multidiscipline feasibility study, providing project management and the electrical, instrumentation, and controls scope while partners covered civil, mechanical, structural, and process work. The study evaluated valve automation, dewatering-well conversion, solar power, telemetry-connected monitoring, and treatment and lift-station upgrades, producing a design a contractor could bid and build to bring discharge to permissible levels.
