The West Lake Landfill is an unlined mixed-waste landfill located in Bridgeton, Missouri, near St. Louis and the Mississippi River, whose contents have been shown to include radioactive waste; it is thus also an EPA Superfund cleanup. It is operated by Bridgeton Landfill, LLC; Rock Road Industries, Inc.; and CotterCorporation …Contamination from this landfill containing nuclear-weapons-related waste likely has migrated off-site, according to a study published in the Journal of Environmental Radioactivity...The U.S. Environmental Protection Agency, have said their radiation sampling hasn’t shown evidence of the site posing a threat to the public.
The study’s authors, who include Robert Alvarez, a former senior Energy Department official in the Clinton administration, said they gathered more than 200 samples of soil and sediments from a roughly 75-square-mile area around the landfill. Dozens of the samples contained levels of radioactive lead that exceeded a cleanup standard used in the past by the federal government, the study said. With West Lake being the largest known nearby repository of radioactive material, the findings are “strong evidence” of the landfill being the primary source, the study concluded. Radon gas is likely escaping from the site and decaying into radioactive lead, said the study. Some of the highest levels were found in dust samples from several homes, said Mr. Alvarez. Those locations ” deserve further attention,” he said. Mr. Alvarez, who has been critical of many federal nuclear policies, said some of the contamination, particularly in the homes, could be residue from old above-ground weapons-waste storage sites that were in the area until the early 1970s, when what was left was buried at West Lake.
For instance, as previously reported, federal surveys have found yards of some homes near a tainted creek that runs through the area to be contaminated with low levels of radioactive material, mainly thorium…..
