ABSTRACT:
A process for removing solvent from soil and debris comprised of the steps of removing the solvent by soil vapor extraction and then washing the soil with a mixture of solvent eating bacteria, nutrients, and water is shown. The process decreases overall capital costs of solvent extraction systems, allows flexibility to size the equipment according to the needs at the individual clean-up site, allows for the purchase of "off the shelf" equipment, allows for easy transportation from site to site, operates more energy efficiently than current art, reduces material handling problems, and reduces the possibility of air emissions.
