Clients & Projects

U.S. Department of Energy

We are managing the nuclear liabilities for the U.S. Department of Energy (DOE) by reducing the overall footprint of the nuclear weapons complex, remediating the sites and, in some cases, returning them back to the local communities.


Idaho Cleanup Project

By honoring commitments to stakeholders, reducing risks to people and communities, and relieving future generations of environmental and financial liabilities, this extraordinary cleanup program is helping the Idaho National Laboratory continue a critical research and development mission that began more than 63 years ago.

West Valley Decommissioning Project

West Valley Phase 1 Decommissioning Project

In the small, quaint town of West Valley, New York, CH2M works year-round against harsh and challenging conditions to successfully decommission a former high-level nuclear waste vitrification facility and protect the environment. 

We are pleased to be recognized by DOE for delivering work safely across the complex. Our success is a result of the commitment, dedication, and creativity of our decommissioning and waste management folks, from senior project managers to waste specialists to project control professionals.
