ORONOGO-DUENWEG MINING BELT
Superfund Site Profile
The Oronogo-Duenweg Mining Belt Site includes numerous mine waste areas that are spread across roughly 270 square miles in southwest Jasper County, and part of northwest Newton County, Missouri. Former mining and smelting operations contaminated soil, groundwater, and surface water sediments with lead, zinc and cadmium. Over 10 million tons of surface mining wastes contaminated about 11,000 acres of the site. Cleanup activities and monitoring are ongoing.
