Amentum specializes in the assessment, monitoring, and remediation of contaminated groundwater at federal, state, and commercial sites. Our hydrogeologists, environmental engineers, and remediation specialists design and implement solutions for a wide range of contaminants-including chlorinated solvents, petroleum hydrocarbons, metals, and per- and polyfluoroalkyl substances (PFAS). We employ proven and innovative treatment technologies, including pump-and-treat, permeable reactive barriers, in situ chemical oxidation and reduction, and enhanced bioremediation, to achieve cleanup goals efficiently. Amentum manages long-term monitoring programs and works proactively with regulators to move sites toward closure.
