In the past government and private industry have produced hazardous waste in ever increasing quantities. These untold millions of tons of environmentally dangerous wastes have been disposed of by undocumented burial, simple carelessness, and purposeful abandonment. Society has recently dictated that before new construction may be initiated, these wastes must be found and cleaned up. The first step is to locate these undocumented waste depositories. The noncontact, nondestructive, remote sensing techniques of computer enhanced IR thermography and ground penetrating radar, may be used to detect buried waste sites, buried tanks/pits, and tank/pit leak plumes. These technologies may be used from mobile vehicles, helicopters, or man-portable systems and are able to cover tens of acres per day depending upon the system fusion method used. This relatively new combination of technologies will be described in theory by procedure and the use of case studies based upon successful projects.
