The United States US Army and the other services are mandated to comply with all federal, state, and local environmental regulations. Recent concerns over potential human exposure to depleted uranium DU at US Army test ranges, primarily, have resulted in research into numerous innovative remediation technologies. Developing methods and processes for estimating the life cycle costs LCC of implementing these various techniques is important in identifying cost-effective solutions. Total ownership costs TOC models were developed for four candidate alternatives using two new technologies Alternative 1- Physical Separation and Chemical Treatment Alternative 2- Selective Excavation Alternative 3- Selective Excavation with Physical Separation and Chemical Treatment Alternative 4- Containment and Monitoring. The team chose a generic sandy soil site roughly 10 miles square for cost estimates. A bottom up estimate was applied to all alternatives in order to get a baseline cost Alternative 3 had the best estimate for an efficient and effective remediation method. A cost estimating relationship was generated and simulation-based costing SBC was then applied to Alternative 3. Lastly, two alternatives were evaluated for DU remediation of catchboxes. Identifying the key cost drivers from SBC modeling is significant to future investments in research and development.
