  • Site Description
    Stage of Clean-up: Construction Underway

    Conditions at proposal (October 15, 1984): The Midwest Solvent Recovery Co., Inc. (MIDCO) II Site occupies approximately 7 acres across the highway from the airport in Gary, Lake County, Indiana. The area is primarily industrial. MIDCO II recycled solvents and disposed of industrial waste at the site using the following methods: temporary storage of waste and reclaimable material in tanks and drums and disposal of wastes via open dumping in trenches, sludge pits, and filter pits. The company operated until August 17, 1977, when a fire burned most of the above-ground tanks and drums containing wastes. Following the fire, the company abandoned the site without cleanup. Several thousand drums containing burned residues were left on-site, along with several tanks. Soils, ground water, and possibly surface water are contaminated, according to tests conducted by EPA. About 479,000 people live within 3 miles of the site. Status (June 10, 1986): Between January and March 1985, EPA used CERCLA emergency funds to remove 85,500 drums and drum remnants, which cleared the site of surface wastes. In July and August, EPA excavated approximately 5,000 cubic yards of highly contaminated soil from a former sludge pit and filter bed and piled the solidified soil on-site.  More...

    Sources of Contamination:
    • Dumping - unauthorized
    • Inadvertent spill
    • Landfill
    • Recycling (Other than primary operation)
    • Storage - drums/containers of waste
    • Waste tank - above ground
    • Waste tank - below ground

  • Threats and Contaminants
    Contaminants affecting the groundwater include VOLATILE ORGANIC COMPOUNDS (VOCS) such as METHYLENE CHLORIDE, BENZENE, TOLUENE, and TRICHLOROETHYLENE (TCE); other organics including isophorone; cyanide; and ARSENIC, LEAD, and other HEAVY METALS. The groundwater also is so highly contaminated with SODIUM and POTASSIUM chloride that it is unacceptable for a surface water discharge even if treated to remove hazardous substances.  More...
