Borehole radar (BHR) measurements, collected adjacent to a landfill site, demonstrate the useful application of this technique in understanding the near surface (upper 30m) hydrogeological conditions. The stratigraphy consists of relatively uniform ice-contact sand deposits, with the water table at a depth of 16.5 m. Zero offset gathers provide a simple technique for defining stratigraphy, water content and contaminate delineation. Multiple offset gathers, before and during a water injection experiment, demonstrate that velocity tomograms can image water content changes on the order of 0.5 percent.
