In March of 1994, the U.S. Department of Energy Office of Science and Technology performed a subsurface ground freezing demonstration at the Scientific Ecology Group (SEG) test site in Oak Ridge, Tennessee. The objective of this demonstration was to evaluate the effectiveness of frozen soil barriers to isolate point sources of contamination by surrounding the contaminant by an impermeable wall of frozen soil. The engineering results of this study can be found in SEG`s final report, and in the 1995 Proceedings of the International Containment Technology Workshop. The ground freezing demonstration at SEG extended from March to October of 1994. At the end of the demonstration, MIT`s Earth Resources Laboratory was invited to test the utility of ground penetrating radar (GPR) to help characterize the structure and integrity of the frozen soil barrier. This paper reports the results of these investigations which were performed on November 5 and 6 of 1994.
