Contaminants such as lead, zinc, and cadmium remain as cleanup efforts are still ongoing today. So far, EQM has assisted with the following:
Excavated, consolidated, and transported over 2.4M cubic yards of arsenic, lead, and zinc-contaminated soil from 32 properties over 770 acres.
Developed, constructed, and filled a 60-acre repository with stormwater retention basins, let-down channels, and rip-rap swales.
Transported waste and contaminated soil to repository.
Performed site restoration activities – fine grading and hydroseeding of 32 disturbed hours.
Removed sediments with visible chat/mine waste from a 1500-foot stream.
Excavated banks and stream bottom and restored stream.
