Chlorinated volatile organic compounds (CVOCs) in fractured, low permeability media can be a long-term source of groundwater contamination, and they are among the most challenging sites for remediation. The objective of this research is to characterize contaminant mass transfer in low permeability clays at boiling temperatures. The research is motivated by the need to advance understanding of the thermal remediation of tight sediments containing CVOCs. The experimental design considers a cylinder normal to the plane of a fracture. 1,2-dichloroethane (DCA) was dissolved in degassed water...
