More radioactive material has been found at the West Lake Landfill in Bridgeton.
The material was detected during radioactivity testing in preparation for the construction of a trench. That trench will separate radioactive waste at the West Lake Landfill from an underground fire smoldering at the adjacent Bridgeton Landfill.
The U.S. Environmental Protection Agency is overseeing the construction of the firebreak trench.
Preliminary work to build a firebreak at the Bridgeton Landfill will begin next week. But a local environmental group is worried about what it could stir up.
To figure out where they can safely dig the trench that will separate the underground fire from the radioactive waste, contractors will test the soil for radioactivity. That involves clearing trees and shrubs away from where the firebreak will be built.
A federal audit has raised questions about the way a St. Louis social service agency spent a $2 million federal stimulus grant to retrofit diesel engines.
Grace Hill Settlement House received the grant in 2009 to install pollution-reducing technologies in vehicles like fire trucks, school buses and tugboats. It was part of the American Recovery and Reinvestment Act.
According to the EPA, approximately 140,000 tons of ash containing heavy metals and other toxic substances contaminated Jefferson County wetlands, an unnamed tributary to Plattin Creek and a portion of Willers Lake.
Residents of Saint Louis, Franklin County and Jefferson County staged a “Miss and Mr. Toxic Water Pollution” pageant on the banks of the Mississippi River on Tuesday to draw attention to the issue of water contamination from Missouri's coal-fired power plants.
