This revision of PNNL-13895 is an updated version of the original document. The changes in this document include the addition of K d data for iodide and uranium that became available during fiscal year 2003. Supplementary data are also included regarding the sediment and solution characteristic used in the studies. This document compiles in a single source the K d values measured with Hanford sediment for radionuclides and toxic compounds that have the greatest potential for driving risk to human health and safety in the vadose zone and groundwater at the Hanford Site. A small number of available K d values that had limited documentation and could not be readily evaluated were excluded from this compilation. In addition to the actual K d values, all significant experimental parameters and solution and sediment characterization data associated with these K d values have been compiled and documented as part of this task. These data will be compiled and made available on a site wide database. This database will be periodically updated as new data become available.
