DOE Environmental Management Los Alamos Strategic Vision Development
In 2022, the Department of Energy (DOE) Environmental Management Los Alamos (EM-LA) initiated the development of a long-term strategic vision for future LANL Legacy Cleanup Campaigns. The goals of the EM-LA strategic vision are to enhance stakeholder engagement in cleanup decisions, and to align with the objectives of the Los Alamos Legacy Cleanup Contract, regulatory interfaces, anticipated cleanup funding and desired outcomes. The EM-LA strategic vision will be integrated with DOE’s broader goals for the legacy cleanup completion.
Our Top Priorities
In cleaning up legacy waste, or waste generated before 1999, we are working in two key areas: Environmental Remediation and Waste Management. Our goal is to clean up the environment and protect our natural resources.
Groundwater and surface water monitoring, chromium and RDX plume monitoring, and waste site characterization and remediation
Hazardous and radioactive waste characterization, management, packaging and transportation off-site for permanent disposal
