The state of Montana today announced its chosen method of cleanup at a Missoula railyard.
Among the contaminants in the site’s groundwater and soil are arsenic and benzene according to the Montana Department of Environmental Quality. The agency’s prescribed remedy includes bioventing, which uses oxygen and microorganisms to clear contamination from soil.
The Burlington Northern Missoula State Superfund Facility earned superfund status in the 1990s. BNSF Railway Company, which formerly owned the facility, is responsible for $3.5 million in cleanup costs. The DEQ expects cleanup to take 30 years
