Navarro is a teaming subcontractor to the Idaho Environmental Coalition and supports the Idaho Cleanup Project which is responsible for the environmental cleanup of the Idaho National Laboratory – a site contaminated with legacy wastes generated from WWII-era conventional weapons testing, government-owned research and defense reactors, spent nuclear fuel reprocessing, and laboratory research and defense missions. Specific areas of support include environmental remediation, facility D&D, environmental compliance, environmental monitoring, and engineering. Other program management activities are also performed to support projects such as closure of the Radioactive Waste Management Complex and design of a new onsite disposal cell within the Idaho CERCLA disposal facility.
