Description:

The BioGenesis Enterprises, Inc. (BioGenesis) soil washing technology was demonstrated as part of the US Environmental Protection Agency's (EPA) Superfund Innovative Technology Evaluation (SITE) program in November 1992. The demonstration was conducted over three days at a petroleum refinery where soils were contaminated with crude oil. The BioGenesis soil cleaning process consists of two stages. In the first stage, contaminants are transferred from the soil matrix to a liquid phase using a proprietary surfactant solution. In the second stage, the surfactant solution enhances biodegradation of residual contamination in soil. For the SITE demonstration, three runs were conducted over three days, each treating 18 cubic yards of soil. Based on chemical analyses conducted on soils collected prior to the demonstration, total recoverable petroleum hydrocarbon (TRPH) was selected as the parameter of concern for the SITE demonstration. TRPH concentrations were monitored in treated and contaminated soils, water, and wastewater. Results of chemical analyses show that TRPH levels decreased by 65–73% in washed soils. The TRPHs in residual soils indicate that soil washing and biodegradation together removed 85–88% of TRPH after 120 days. The treatment system's performance was found to be reproducible at constant operating conditions. This paper presents an introduction, a technology description, the experimental design of the SITE demonstration, SITE demonstration results, and conclusions.
