The Dixon Iron and Metal Company (DIMCO) is a former scrap metal recycler that operated from the 1940s until 2017. DIMCO is located at 78 Monroe Ave in Dixon, IL, adjacent to the Rock River, residential, commercial, and industrial properties. In 2018 Illinois EPA and/or their contractor conducted soil, groundwater, and soil vapor sampling as part of a Brownfield Redevelopment Assessment. The property was acquired by the City of Dixon in 2019.

Polychlorinated biphenlys (PCB), metals, volatile organic compounds (VOCs), and semi-volatile organic compounds (SVOCs) were detected in surface soils (two feet or less) based on Illinois EPA sample results. However VOCs and SVOCs were below EPA removal management levels (RMLs). The most notable near-surface contamination is PCB concentrations of 600 mg/kg (SB19), lead at 93,400 mg/kg (SB11), and TCLP lead at 52.8 mg/L (SB19).

The Superfund Division Director signed an action memorandum on May 29, 2019, to document approval to conduct a time-critical removal action. The time-critical removal action will include removal of lead contaminated soil above 400 milligrams per kilogram (mg/kg) to 24-inches, PCB contamination above 25 mg/kg within the first 24-inches, and PCB contamination above 50 mg/kg to groundwater. PCB contaminated soil above 25 mg/kg will be capped.

Removal activities are starting August 13, 2019, and are anticipated to last 8 to 12 weeks.
