The owners of the West Lake Landfill in Bridgeton, Mo., are suing Mallinckrodt LLC to help pay costs of the U.S. Environmental Protection Agency (EPA) cleanup. The EPA ordered a $205 million cleanup to remove radioactive waste from the site.

According to a St. Louis-Dispatch report, Mallinckrodt's predecessor, Mallinckrodt Chemical Works, processed uranium at its factory in St. Louis that was used in the U.S. government's Manhattan Project, a World War II-era program that produced the first nuclear weapons. In 1973, about 8,700 tons of leached barium sulfate from the weapons program was “mixed with approximately 38,000 tons of contaminated soil and used to cover trash being dumped” at the landfill, according to the EPA.

The $205 million cleanup calls for excavating about 70 percent of the landfill's Manhattan Project-era radioactivity and disposing of it out of state.
