A -- LARGE-SCALE DEMONSTRATION FOR TREATMENT OF PRIMARILY TRICHLOROETHENE CONTAMINATION IN LOW PERMEABILITY SOILS (PACKED CLAY) AT THE PADUCAH GASEOUS DIFFUSION PLANT POC Contact Point, Maurice Davis 615 576-7599, Contract Specialist; Nancy Frolio 615 576-4094, Technology Development The Department of Energy anticipates awarding a follow-on sole source contract with the Monsanto Company for large-scale demonstration of the Lasagna technology with an option to extend the scope to entire site which is approximately one-half acre. The Lasagna technology has been developed and tested to treat trichloroethene (TCE) contamination in low permeability soils (packed clay) at the Paducah Gaseous Diffusion Plant. The Lasagna technology, a Monsanto patented process, incorporates both innovative and standard technologies into a system that has been demonstrated to be effective in removingTCE from low permeability soils at a cost significantly less than baseline technologies. Treatment zones are emplaced in the subsurface and electro-osmosisis used to move contaminants into these zones. This sole source is focused on completing development and conducting large scale demonstration of the Lasagna technology to assess the scale-up factors, to evaluate the ability to destroy thecontaminant in the treatment zones and to assess the cost on a large-scale to ensure it is still cost effective when compared to the baseline. Based on a successful large scale demonstration, an option will be available to deploy the technology for treating the remainder of the one-half acre site. See Numbered Note 22. (0243)
