The report analyzes the results of the SITE Program demonstration of BioTrol's Soil Washing System at the MacGillis and Gibbs wood treatment facility in New Brighton, MN. The contaminants of primary interest are pentachlorophenol (penta) and polynuclear aromatic hydrocarbons (PAHs). From tests with two soils (130 mg/kg and 680 mg/kg penta), it is concluded that the soil washer effectively segregates contaminated soil into a large fraction of relatively uncontaminated washed soil, a small fraction of fine clay and silt retaining about 30% of the original penta contamination, contaminated woody debris and contaminated process water. Biotreatment of the process water from the two soil washing tests degraded 91-94% of the penta; removal of PAHs could not be determined. While steady state was not achieved, the biological treatment of the contaminated fines in a Slurry Bio-Reactor suggested that >90% removal of penta and PAHs could be achieved with a fully acclimated system. Combined operating and capital costs for an integrated, full-scale system are estimated to be $168/ton of soil treated; incineration of the woody debris is a major cost factor.
