In a settlement announced Wednesday, the U.S. Department of Justice, Environmental Protection Agency and the state of Missouri ordered metal and mining company Doe Run Resources Corporation to clean up lead contamination in more than 4,000 residential properties in St. Francois County.
The work is estimated to cost a total of $111 million. Of that, the Environmental Protection Agency will contribute about $31 million. The company will remove lead contamination in the Big River Mine Tailings Superfund Site, an area added to the EPA's National Priorities List in 1992. It's part of Missouri's "Old Lead Belt," one of the largest lead mining districts in the world.
