Environmental Remediation and Decommissioning

Amentum is a leading provider of comprehensive environmental remediation and decommissioning services, with over a century of experience delivering innovative solutions to complex environmental challenges. Our expertise encompasses the decontamination, dismantling, deactivation, and demolition of high-hazard facilities, as well as the remediation of contaminated land and water resources. We have successfully executed projects at some of the world’s most challenging sites, including the Sellafield nuclear facility in the UK, Fukushima Daiichi Nuclear Power Plant in Japan, and Department of Energy legacy Manhattan Project Sites such as Hanford, the Savannah River Site, West Valley, and Oak Ridge Reservation. Amentum has consistently delivered innovative solutions for deactivating, decommissioning, and remediating contaminated facilities, while addressing soil and groundwater contamination with advanced treatment technologies. Amentum also brings decades of experience supporting the US Army Corps of Engineers under the Formerly Utilized Sites Remedial Action Program as well as nuclear reactor Decommissioning programs.

These projects showcase Amentum’s ability to manage high-hazard, technically complex remediation efforts, utilizing advanced engineering, cutting-edge technologies, and industry-leading safety protocols. With a steadfast commitment to regulatory compliance and environmental stewardship, Amentum is uniquely equipped to tackle the world’s most challenging remediation missions.

We see decommissioning and remediation as both a challenge and an opportunity. The challenge is to optimize timelines and costs without compromising on safety. The opportunity is to maximize local economic impact, driving transformational change and creating lasting social value through decommissioning. To unlock the potential for shared value from investment in nuclear clean-up, we build stronger relationships between clients, supply chain partners and local communities.
