Technical Abstract: One of the more frustrating problems confronting farmers and land improvement contractors in the Midwestern United States involves locating buried agricultural drainage pipes. Conventional geophysical methods, particularly ground penetrating radar (GPR), presently being used for environmental and construction engineering applications can potentially provide a solution to this problem. Scientists and engineers from the USDA-Agricultural Research Service, the Ohio State University (OSU) ElectroScience Laboratory and the OSU Department of Geological Sciences collaborated in an extensive study funded by the Ohio Agricultural Research and Development Center. They found that GPR was quite successful in detecting clay tile and corrugated plastic tubing drain pipe down to depths of around 3 feet (1 meter)in a variety of different soil materials. GPR grid surveys were conducted in Ohio at 11 test plots containing subsurface drainage systems. The technology proved to be 81 percent effective in locating the total amount of pipe present.
