The 4-acre Midco I site is an abandoned, industrial waste recycling, storage, and disposal facility in Gary, Indiana. The surrounding land use is mixed industrial, commercial, and residential. The Calumet Aquifer underlies the site and provides drinking water to wells within 1 mile of the site. The primary contaminants are VOCs, including TCE, toluene, and xylenes; metals, including chromium and lead; and inorganics. The amended remedial action for the ROD includes a reduction in the amount of soil to be treated to a minimum of 5,200 cubic yards because of the amendment to soil CALs and the determination that arsenic may not be present above background levels at the site; and treating the contaminated soil onsite using with soil vapor extraction, followed by in-situ solidification/stabilization; and excavating and treating contaminated sediment from the surrounding wetlands.
