||This report summarizes the U.S. Environmental Protection Agency (EPA) Superfund Innovative Technology Evaluation (SITE) Program evaluation of the In Situ Thermal Destruction (ISTD) technology developed by others and refined by TerraTherm, Inc. The demonstration was designed to evaluate the technology's ability to treat soil-and-waste material contaminated with hexachlorocyclopentadiene (hex) and chlorinated pesticides at a former disposal pit (the Hex Pit) located at the Rocky Mountain Arsenal in Commerce City, Colorado. Operation of the system was terminated soon after initial startup and before the SITE demonstration could be completed, due to the destruction of system components from highly corrosive vapors and liquids. ISTD is a soil remediation process that applies heat and vacuum simultaneously to contaminated soils, either with surface heater blankets or with an array of vertical heater and vacuum extraction wells. The ISTD system at the Hex Pit used an array of vertical heater and combination heater and vacuum extraction wells.
