PREFACECun'cnfly available technology is not adequate to assess environmental contamination at Department of Energy (DOE) sites, take permanent remedial action, and eliminate or minimize the environmental impact of futm'eoperations. Technical resources to address these shortcomings exist within the DOE community and the private sector, but the involvement of the private sector ] in attaining permanent and cost=effective solutions has been limited. L During 1990, on bohalf of DOE's Office of Technology I_velopment, Argonne Nadonal Laboratory (ANL) conducted a competitive procurement of research and development projects addressing soil remediation, groundwater remediation, site characterization, and contaminant containment, Fifteen contracts were negotiated in these areas. This report documents work performed as part of the Private Sector Research and D_velopment Program sponsored by the DOE's Office of Technology Development within the Environmental Restoration and Waste Management Program. The research and development work described herein was conducted under contract to ANL.On behalf of DOE and ANL, I wish to thankthe performing contractor and especially the report authors for their cooperation and their contribution to development of new processes for characterization and remediation of DOE's environmental problems. We anticipate that the R&D investment described here will bc repaid many-fold in the application of better, faster, safer, and cheaper technologies.Details of the procurement process and status reports for all 15 of the contractors performing under this program can be found in "Applied Research and Development Private Sector Accomplishments = Interim Report" (Report No. DOE/CH-9216
