area of a Superfund site in Missouri, but the agency says it still has a ways to go.The Joplin Globe reports that the agency's cleanup contract expires in 2020 for the Oronogo-Duenweg Mining Belt. The nearly 7,000-acre (2,833 hectare) site in Jasper County received Superfund designation because it was contaminated by about 10 million tons of mining waste.
Crews in recent months have removed mine waste and covered scarred land with clean soil on what's known as the Snowball site.
Several people who privately own the Snowball site say they don't have
immediate plans to redevelop the land.
So far, the agency has cleaned about 1,600 acres (648 hectares) of the overall Superfund site.
