Description:
In support of the U.S. Environmental Protection Agency's (EPA) Superfund Innovative Technology Evaluation (SITE) Program, this report evaluates the Chemfix Technologies, Inc. (Chemfix), solidification/stabilization technology for on-site treatment of hazardous waste. The Chemfix technology mixes and chemically treats waste material with proprietary additives and water in a patented pugmill to form a more stable material. This report evaluates treatment efficiency and economic data from the SITE demonstration of the Chemfix technology and other past applications. The Chemfix demonstration was conducted at the Portable Equipment Salvage Company (PESC) site in Clackamas County, Oregon, in March 1989. The PESC site was a transformer and metal salvage facility. Activities at the site left the soil contaminated with polychlorinated biphenyl (PCBs), lead, copper, and other metals. Four on-site areas that differed in soil type and contaminant concentrations were selected to test the Chemfix process on a range of feed materials. Approximately 7 to 8 cubic yards of contaminated soil were excavated from each area and treated. Extensive waste material sampling and analysis were performed before and after treatment so that physical, chemical, and leaching properties could be compared. According to results from the Toxicity Characteristics Leaching Procedure (TCLP), the Chemfix technology is capable of decreasing the mobility of cadmium, copper, chromium, lead, nickel, and zinc. Lead and copper removals greater than 95 percent were achieved. Available data do not allow conclusions to be drawn regarding the effectiveness of the Cemfix technology in stabilizing organic contaminants or in dechlorinating PCBs. Demonstration data suggest partial dechlorination of PCBs; however, no byproducts of complete dechlorination were found.
