Ground freezing for hazardous waste containment is an alternative to the traditional and expensive slurry wall or grout curtain barrier technologies. The parameters quantified in this analysis of it include thermal properties, refrigeration line spacing, equipment mobilization and freezing time constraints. The economics of the process is discussed based on the Poetsch method for ground freezing. Vertical drill holes with concentric refrigeration lines are spaced along the desired freezing line. Temperature-measuring instrumentation is appropriately placed to monitor the progress of the freeze front. Plotting costs for equipment rental, drill expenses, fuel costs and time as a function of refrigeration line spacing produces an overall expense estimate that can be used to compare ground freezing with other barrier construction technologies.
