District Context & Mission Impact
This critical environmental restoration contract is administered by the U.S. Army Corps of Engineers Detroit District in support of federal and state environmental cleanup programs. The Detroit District manages Great Lakes water resources, commercial navigation channels, and environmental engineering projects throughout Michigan and the upper Great Lakes basin. The Tar Lake Superfund Site, a former iron manufacturing and chemical production waste impoundment in Antrim County, accumulated creosote-like tar wastes that impacted localized soils and groundwater reserves. Executing targeted soil excavation along with expanding in-situ bio-sparging—a process injecting pressurized air into subsurface groundwater to stimulate microbial degradation of organic contaminants—protects surrounding drinking water aquifers and restores land for future community reuse through autumn 2030.
