Having completed full-scale testing of the Lasagna™ treatment technology, an experimental electro-osmosis remediation system developed by Monsanto, Dupont, and General Electric in conjunction with the EPA and DOE, CDM applied this innovative technology to a larger area of trichloroethene (TCE) contamination at the Paducah gaseous diffusion plant. Lasagna uses electrokinetics to move TCE-containing soil and water through treatment zones installed in situ to form an integrated remedial process. TCE is captured and decomposed into non-hazardous compounds as it comes into contact with the iron fillings in the treatment zones.
After 2 years of operation, TCE concentrations at the site dropped from an average of 84 milligrams per kilogram (mg/kg) to 0.38 mg/kg, far below the project's goal of 5.6 mg/kg. CDM has provided operations and maintenance support during normal operations by performing routine maintenance and weekly equipment and system checks of key process variables to record operational data and ensure effective and safe system operation.
