National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Hanford Contaminant Distribution Coefficient Database and Users Guide.

DE200215001324

Publication Date	2002
Personal Author	Cantrell, K. J.; Serne, R. J.; Last, G. V.
Page Count	88
Abstract	The purpose of this work is to compile and thoroughly document all useful distribution coefficient data determined for Hanford sediment and related materials into one database. This report provides the background information to access the database and provides guidance on how to properly and effectively apply the information in the database to select appropriate K(sub d) values for numerical transport modeling efforts. A part of this work will be to identify significant data gaps and technical needs and make appropriate recommendations. The intent of this work is to maximize the value of existing K(sub d) data, ensure consistency, and eliminate duplication of effort among various programs. An additional purpose of this work is to increase the defensibility of the linear isotherm model that will be used in SAC Rev. 1 and other up coming performance assessments. The work will provide transport modelers guidance for selecting appropriate K(sub d) values for various conditions that are consistent and scientifically defensible rather than excessively conservative.
