Arctic Foundations, Inc. (AFI), of Anchorage, Alaska has developed a freeze barrier technology designed to prevent the migration of contaminants in groundwater by completely isolating contaminant source areas until appropriate remediation techniques can be applied. With this technology, contaminants are contained in situ with frozen native soils serving as the containment medium. The U.S. Environmental Protection Agency's (EPA) Superfund Innovative Technology Evaluation (SITE) Program evaluated the technology at the U.S. Department of Energy's (DOE) Oak Ridge National Laboratory facility in Oak Ridge, Tennessee from September 1997 to July 1998. For the evaluation, an array of freeze pipes called 'thermoprobes' were installed in a box-like structure around a former waste collection pond. The thermoprobes were installed vertically to a depth of 32 feet below ground surface and anchored in bedrock. The thermoprobes were connected to are frigeration system by a piping network. A cooled refrigerant (R404A) was circulated through the system to remove heat from the soil.
