What is one method used to locate UXO?

Ground-penetrating radar (GPR) is an effective method used to locate unexploded ordnance (UXO) due to its ability to provide high-resolution images of subsurface features. This technology utilizes radar pulses that are transmitted into the ground, which then reflect off different materials and structures beneath the surface. The data collected allows operators to identify anomalies, such as metallic objects associated with UXO, providing a non-intrusive way to survey the area before conducting any physical excavation or removal operations.

While visual inspection is limited to surface observations and geographic mapping does not provide subsurface insights, and magnetic surveying has its own set of limitations in terms of object types it can reliably detect, GPR offers a more detailed and direct approach to identifying buried ordnance. Its ability to differentiate between various subsurface materials enhances the accuracy of locating UXO, making it a preferred choice in this context.
