The Remediation Decision Support (RDS) project, managed by the Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy (DOE) and the CH2M HILL Plateau Remediation Company (CHPRC), has been compiling physical and hydraulic property data and parameters to support risk analyses and waste management decisions at Hanford. In FY09 the RDS project developed a strategic plan for a physical and hydraulic property database. This report documents prototype data models and dictionaries for these properties and associated parameters.v

“…Based on Kos' contaminant visualizations (DOE 1998b), the cesium-137 and cobalt-60 plumes appear to have migrated to a depth of 120 ft bgs and 80 ft bgs, respectively. Generally, cesium-137 is much less mobile than cobalt-60 (see other tank farm borehole reports such as Serne et al 2002aSerne et al , 2002bSerne et al , 2002cSerne et al , 2002dSerne et al , 2002e, 2002f, and 2004 ) data compilations by EPA 1999 andCantrell et al 2003) so the DOE (1998b) data and interpretation are unique.…”

To meet this goal, CH2M HILL Hanford Group, Inc. tasked scientists from Pacific Northwest National Laboratory (PNNL) to perform detailed analyses on vadose zone sediments from within Waste Management Area (WMA) C. This report is the first of two reports written to present the results of these analyses. Specifically, this report contains all the geologic, geochemical, and selected physiochemical characterization data collected on vadose zone sediment recovered from borehole C4297, installed adjacent to tank C-105, and from borehole 299-E27-22, installed directly north of the C Tank Farm. This report also presents the interpretation of data in the context of sediment types, the vertical extent of contamination, the migration potential of the contaminants, and the likely source of the contamination in the vadose zone below the C Tank Farm. The information presented in this report supports the WMA A-AX, C, and U field investigation report in preparation by CH2M HILL Hanford Group, Inc. Sediments from borehole 299-E27-22 were characterized for their potential to be used as background (i.e., uncontaminated) sediments against which to compare contaminated sediments during the C Tank Farm characterization effort. Upon analysis of sediment samples from borehole 299-E27-22, elevated concentrations of chloride, nitrate, sulfate, phosphate, magnesium, calcium, strontium, and sodium were encountered at various depths within the borehole. Although no known spills have been recorded at the location where borehole 299-E27-22 was emplaced, the data strongly suggest the sediment has been contacted by a non-radiological waste stream. While the data from borehole 299-E27-22 are presented within this report, it is not recommended that the data be used holistically as background or baseline values for uncontaminated sediment. Instead, data from a companion report (Lindenmeier et al. 2002), which was an investigation of samples from borehole 299-E33-338, should be used for baseline comparisons. A core log was generated for both boreholes and a geologic evaluation of all core samples was performed at the time of opening. Aliquots of sediment from the borehole core samples were analyzed and characterized in the laboratory for the following parameters: moisture content, gamma-emitting radionuclides, one-to-one sediment:water extracts (which provide soil pH, electrical conductivity, cation, trace metal, and anion data), total carbon and inorganic carbon content, and 8 M nitric acid extracts (which provide a...

“…Empirical K d data for Hanford formation and Ringold Formation sediments are fairly abundant for dilute waste solutions and groundwater (Cantrell et al 2002(Cantrell et al , 2003a. Fewer K d data are available for the Cold Creek unit sediments, or for high ionic strength waste solutions with slightly acidic to slightly basic pH values.…”

This data package was originally prepared to support a 2004 composite analysis (CA) of low-level waste disposal at the Hanford Site. The Technical Scope and Approach for the 2004 Composite Analysis of Low-Level Waste Disposal at the Hanford Site (Kincaid et al. 2004) identified the requirements for that analysis and served as the basis for the data collection effort documented in this data package. Completion of the 2004 CA was later deferred, and the 2004 Annual Status Report for the Composite Analysis of Low-Level Waste Disposal in the Central Plateau at the Hanford Site (DOE 2005) indicated that a comprehensive update to the CA was in preparation and would be submitted in 2006. However, the U.S. Department of Energy (DOE) has recently decided to further defer the CA update and will use the cumulative assessment currently under preparation for the environmental impact statement (EIS) being prepared for tank closure and other site decisions as the updated CA.
