The Technical Advisory Group (TAG) of the Innovative Treatment Remediation Demonstration Program (ITRD) made technology recommendations after reviewing thirty in situ remediation technologies for implementation at the Paducah Gaseous Diffusion Plant (PGDP) to treat groundwater contaminated with trichloroethylene (TCE) and technetium-99 (Tc-99). The 1999 data used in the ITRD final report were considered to be obsolete as of the year 2004. In this work, cost and performance of the ITRD recommended technologies were updated and compared to newer technologies not in the original review. The technologies were described and case studies were used to evaluate cost and performance with costs brought up to 2005 values. Bioremediation and In Situ Chemical Oxidation (ISCO) methods proved to be the most effective technologies based on the case studies. Site assessment will determine what technology is the most feasible to implement from the bioremediation and ISCO choices. Permeable Reactive Barriers (PRB) can be effective in preventing contaminant migration. Humic products prove to be very effective on a laboratory scale and warrant further investigation.
