TECHNOLOGY EVALUATION REPORT: SILICATE TECHNOLOGY CORPORATION, SOLIDIFICATION/STABILIZATION OF PCP AND INORGANIC CONTAMINANTS IN SOILS SELMA, CA. U.S. Environmental Protection Agency, Washington, D.C., EPA/540/R-92/010 (NTIS PB95255709), 1995.
Description:
A Superfund Innovative Technology Evaluation demonstration was conducted to evaluate the ability of the solidification/ stabilization treatment process developed by Silicate Technology Corporation (STC) to reduce the mobility and leaching potential of organic and inorganic contaminants in soils. he treatment process is based on STC's proprietary alumina-silicate product, FMS Silicate. he demonstration was held at the Selma Pressure Treating site in Selma, CA, in November 1990. he STC technology,was demonstrated using contaminated soils from an unlined waste disposal pond at this site that contained significant levels of pentachlorophenol (PCP), arsenic, copper, and chromium. he evaluation of STC's treatment process was based on (1) contaminant mobility, as measured by several leaching tests and total waste analysis; (2) structural integrity of the solidified material, as measured by physical, engineering, and morphological tests; and (3) economic factors based on cost information from STC supplemented by information from the demonstration. reated soil from the demonstration was monitored for a period of 32 mo, ending in July 1993.
