Area 7 Emergency QBS Memo Signed.pdf

This is a memorandum from the Illinois Environmental Protection Agency (IEPA) regarding an Emergency Quality Based Selection procurement for continued work at the Southeast Rockford Superfund Site Area 7 in Winnebago County, Illinois. The site, located in the southeast portion of Rockford, encompasses approximately 3 miles by 2.5 miles and includes Ekberg Park, which contains recreational facilities and is bordered by residential homes. The groundwater contamination includes 1,1-Dichloroethene, 1,2-Dichloroethane, 1,2-Dichloroethene, Ethylbenzene, Tetrachloroethene, 1,1,1-Trichloroethane, Trichloroethene, and Vinyl Chloride. The selected remedy involves groundwater containment with collection and treatment, multi-phase extraction wells, groundwater and soil gas treatment, monitoring, and restrictions on groundwater usage. The contract is intended to continue site work through the end of 2026.

This Emergency Quality Based Selection procurement is classified as a stop-gap measure necessitated by the expiration of the current contract and the critical nature of protecting public health and environmental safety. Immediate services are necessary to maintain the treatment system's functionality and prevent exposure to the large residential area adjacent to the site. The remedial design is in final stages approaching remedy selection, with federal funding tied to this work plan. The memorandum was dated October 31, 2025, and signed by Andrew Shackelford on behalf of the Bureau of Land procurement authority.
