Description:
The Environmental Protection Agency has conducted a series of bench-scale and pilot-scale studies to evaluate the feasibility of washing pentachlorophenol (PCP) and creosote from the soil at an abandoned wood-treatment Superfund site in Pensacola, FL. he high sand content and low silt/fines content of the soil made soil washing a promising alternative to incineration. he bench-scale tests confirmed the feasibility of washing the PCP and the carcinogenic creosote compounds from the soil using a nonionic surfactant at a pH of one to ten and a water temperature of approximately 120 degrees F. he target concentrations for total creosote were not achieved, but the results were sufficiently close to warrant further testing. he pilot-scale tests using the EPA's while Volume Reduction Unit produced residual PCP, carcinogenic creosote, and total creosote levels below the target levels. he tests also produced comparison data on the effects of surfactant concentration, pH, temperature, and liquid solid ratio.
