The SASW method was applied to determine the depths of three covered landfill cells on the Tonopah Test Range (NV), which potentially contained unexploded ordnance. The cells were approximately 10 m wide and 40-80 m in length.  Along with crosshole radar measurements made by another contractor, these investigations were applied to develop a drilling plan, which would enable investigation of the soil close to the cell bottoms without penetrating the cells themselves.
