In an agreement between the U.S. Environmental Protection Agency (EPA) and the Michigan Department of Environmental Quality (MDEQ), $9.7 million has been dedicated to fund a cleanup remedy at the Velsicol Superfund Site in St. Louis, Mich.

The 54-acre main plant site produced various chemical compounds, including DDT (dichloro-diphenyl-trichloroethane), from 1936 to 1978.  The funding is for underground thermal heating.  Contaminated soil and groundwater is heated to approximately the boiling point of water.  The water and vapors are captured and treated on site aboveground.  This type of treatment reduces the risk to workers and the community.  The system should be installed and begin heating the soil in late fall.
The agreement provides for a 90-10 split in cost of remedies implemented by EPA.  The State of Michigan’s cost share is $970,000.
