Hydrologic characterization of the vadose zone (from soil surface to the underlying water table) is needed to assess contaminant migration from buried wastes. The Pacific Northwest National Laboratory, under contract with the U. S. Department of Energy’s EM-50 (Subsurface Contamination Focus Area), and in collaboration with CH2MHILL Hanford Group, the Idaho National Engineering and Environmental Laboratory (INEEL), and Duratek Federal Services (DFS), deployed a suite of vadose-zone instruments at the Hanford Site near Richland, Washington. Several new instruments were tested.
