At DOE and Department of Defense facilities, EVS has designed and implemented site-specific ecological risk assessments. These projects involve designing and implementing field and laboratory studies, developing species-specific dose models, and developing conceptual models to link contaminants and biota. These site-specific assessments address chemical and radiological contaminants for the DOE Weldon Spring Site Remedial Action project in Missouri, chemical contaminants at the Army’s J-Field site at Aberdeen Proving Ground in Maryland, and depleted uranium at the China Lake Naval Air Station in California.

We applied our expertise to help DOE and the Navy develop policy and guidance related to ecological risk assessment, hazardous materials and waste, background chemicals at cleanup sites, and natural resource injuries during cleanup and restoration. For Navy and Superfund sites, we assisted in developing monitoring plans for contaminated sites, as well as guidance for biomonitoring.

We also developed and conducted environmental restoration training for the Navy and other Department of Defense services through the Naval Civil Engineers Corps Officers School and other avenues. This training includes courses such as Ecological Risk Assessment, Human Health Risk Assessment, Environmental Background Analysis, Environmental Geographic Information Systems/Geostatistics, and Naval Environmental Restoration Program.
