Environmental Risk Assessment

Amentum delivers rigorous environmental risk assessments that characterize contaminant exposure pathways, evaluate human health and ecological risks, and inform cleanup decisions at contaminated sites. Our risk assessors bring expertise in baseline risk assessment, risk-based corrective action (RBCA), and remedial investigation/feasibility study (RI/FS) frameworks for sites regulated under CERCLA (the Comprehensive Environmental Response, Compensation, and Liability Act), RCRA (Resource Conservation and Recovery Act), and state programs. We integrate site-specific data with current toxicological and exposure science to develop defensible risk characterizations that support regulatory negotiations and cleanup optimization. Amentum’s environmental risk assessment capabilities help clients understand their true liability, prioritize remediation investments, and achieve regulatory acceptance efficiently.
