Abstract |
The Airco site is a 2.7-acre industrial waste landfill located outside the zoned area of Calvert City, Marshall County, Kentucky. By 1971, 18,000 tons of caustics, acids, VOCs, zinc and mercuric acetate, and mercuric chloride reportedly were disposed at the site. Air Products and Chemicals, Inc. leased the landfill from Airco until 1980, during which time they disposed of approximately 14,000 tons of coal ash containing low level metal contaminants, as well as polyvinyl chloride solids, ferric hydroxide sludge, and construction waste at the site. The landfill was capped and closed in September 1981. The selected remedial action for the site includes: Excavation and consolidation of approximately 5,000 cu. yds. of contaminated soil and sediments within the dikes and around the landfills from both the Airco and BFG sites, with onsite disposal in the former burn pit area at the BFG site followed by construction of an organic vapor recovery system. |
