Iowa Army Ammunition Plant
Location: Middletown, IA
Client: U.S. Army Corps of Engineers
R8I Cabrera is currently performing remediation of the Iowa Army Ammunition Plant OU-8 (IAAAP) in Middletown, IA. IAAAP encompasses approximately 19,000 acres, including active and inactive production and storage areas, undeveloped areas, and agricultural leases. The Atomic Energy Commission (AEC) operated at portions of IAAAP from 1947 to 1975. Historical operations by both the Army and AEC resulted in releases of hazardous substances to soil, surface water, and groundwater at IAAAP. The primary contaminants of concern at the site include explosives, metals, volatile organic compounds, and depleted uranium (DU).
R8I Cabrera’s five year contract with USACE St. Louis focuses on excavation and removal of contaminated soil and associated debris exceeding the RG of 150 pCi/g DU. Our team will achieve project objectives through the use of a soil sorting system that manages the soil and debris based on its radioactive content. We will segregate DU-contaminated soil and debris from clean soil, and transport and dispose of the waste at an off-site permitted facility. To date on the project, R8I Cabrera has completed work plan development and is currently performing the site set up, construction of temporary facilities and site-required adjustments to the soil sorting system prior to actual field work. After the completion of these tasks excavation and processing of DU-contaminated soil and associated debris will begin. R8I Cabrera excavated and radiologically soil sorted approximately 14,500 cubic yards of soil and debris in 2019, and expects to excavate and sort another 16,500 cubic yards of soil and debris in 2020.
