Public Notice: Washington County Lead District – Old Mines, Potosi and Richwoods Superfund Sites, Old Mines, Potosi and Richwoods, Washington County, Missouri

Summary

Second Five-Year Review Started

The U.S. Environmental Protection Agency (EPA) Region 7 has started the Second Five-Year Review for the Washington County Lead District – Old Mines, Potosi and Richwoods Superfund sites. 

Five-Year Reviews are required by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, when hazardous substances remain on-site above levels that permit unrestricted use and unlimited exposure. Five-Year Reviews provide an opportunity to evaluate the site remedy to determine whether it remains protective of human health and the environment. These Five-Year Review Reports should be completed by November 2026. 

Site project information is available to the public at web repositories. To view cleanup documents, see Site Documents & Data on EPA’s Site Profile pages:
