Highway agencies need a simple, effective, nondestructive way to inspect certain properties in rights-of-way for the possible presence of abandoned underground storage tanks, without disturbing the ground, before actual construction begins. Overall, ground-penetrating radar (GPR) fills this need better than other nondestructive methods. This report explains why GPR was chosen over the other nondestructive methods available, discusses the principle of GPR, describes the basic radar equipment needed and the general procedures involved in conducting such inspections, and provides examples of the type of radar data such inspections produce.
