Evaluation and Demonstration of an Advanced Electromagnetic System for Nonintrusive Underground Surveys
Abstract
This report documents field evaluations of the capabilities of GEM-1, an electromagnetic subsurface surveying instrument. GEM-1 was developed under the Small Business Innovative Research (SBIR) program as a tool for the expedient location of lost underground fuel storage tanks. GEM-1's characteristics allow its application to a variety of nonintrusive subsurface exploration applications. Evaluations conducted by USACERL included successful location and mapping of known and unknown underground storage tanks, pipes, a leach field, and a retired landfill. Searches for small buried pipes and small surface placed ordnance were relatively unsuccessful, however, because the geometry and sensitivity of GEM-1 were designed for significantly larger targets. Many more applications of electromagnetic subsurface exploration will likely become common with the availability of GEM-300, a commercially produced device based on the concepts and capabilities tested in this program.
