Description:
The Risk Reduction Engineering Laboratory (RREL) Releases Control Branch (RCB) has developed a pilot-scale Mobile Volume Reduction Unit (VRU) to determine the feasibility of soil washing for the remediation of contaminated soils. This mobile unit, mounted on two trailers, can process 100 lb/hr of soil feed. Soil washing is a cost effective technology used in conjunction with other methods for remediating contaminated soil. The process reduces the quantity of contaminated material that must be processed by more expensive technologies, such as incineration or bioremediation. In some cases, soil washing may be a successful stand-alone technology. Region VIII of the United States Environmental Protection Agency (EPA) requested the VRU to evaluate soil washing as a treatment for contaminated soil at the Sand Creek Superfund Site in Commerce City, CO. This site contains approximately 14,000 yd3 of soil contaminated with pesticides. Soil washing, a relatively inexpensive technology, might provide a significant cost savings by reducing the volume of soil requiring expensive treatment by incineration. Region VIII defined the objectives of the test: Determine if the soil washing is effective in removing heptachlor and dieldrin from contaminated soil. Determine whether the VRU can achieve the cleanup goals set for the site: less than 0.553 ppm heptachlor and less than 0.155 ppm dieldrin. Estimate the process parameters and cost factors for the full-scale operation. Provide data for process scale-up.
