Doug McKenzie Donald E. Sebo Kirk M. Green Vivian G. Schultz Edited by Lynn Bailey November 2005 Idaho Cleanup Project Idaho Falls, Idaho 83415 Prepared for the U.S. Department of Energy Assistant Secretary for Environmental Management Under DOE Idaho Operations Office Contract DE-AC07-05ID14516 ABSTRACT This report provides the history of the development and updating of various databases leading to development of the Waste Information and Location Database (WILD). WILD contains the inventory of waste buried in the Subsurface Disposal Area, a radioactive waste landfill located at the Radioactive Waste Management Complex, part of the Idaho National Laboratory. WILD makes available the most current and comprehensive information about waste buried in the Subsurface Disposal Area through June 1997 by linking updated estimates of contaminant inventories and burial locations. This report presents the method for verification and validation of WILD to enable its use in the comprehensive remedial investigation and feasibility study by Waste Area Group 7, Operable Unit 7-13/14. A data set was taken from WILD on November 29, 2004, to serve as the source term inventory for the Operable Unit 7-13/14 remedial investigation/baseline risk assessment and feasibility study. This particular data set is referred to as the remedial investigation/feasibility study Snapshot. Subsequent modifications to the source term inventory applied to the Snapshot and used in the remedial investigation/feasibility study will be documented in the remedial investigation/baseline risk assessment report. In addition, this report documents refinement of the waste inventory from the Reactor Technology Complex (formerly Test Reactor Area), enabling this updated information to be included in WILD. iii iv CONTENTS ABSTRACT.................................................................................................................................................iii ACRONYMS............................................................................................................................................... ix 1.
