Mapping subsurface radionuclide migration and groundwater flow with organic tracers. [Shallow-land burial]

Conference ·
OSTI ID:6883521
; ; ;
At Pacific Northwest Laboratory we have had the opportunity to study the subsurface migration of radionuclides at the Maxey Flats burial site. We constructed an experimental study area adjacent to one of the waste-filled trenches at the site. In this report we describe some preliminary results of organic research currently underway at Maxey Flats. This research is aimed at: (1) elucidating the role of organic species in the subsurface migration of radionuclides; and (2) testing the usefulness of artificial and in situ organic groundwater tracers for mapping radionuclide migration and groundwater flow. We also describe two analytical procedures developed for this research. First, as part of a survey study of organics in Maxey Flats groundwater we have developed a procedure for the isolation and characterization of trace levels of organics in radioactive groundwaters. Second, for a detailed chemical speciation study we developed a procedure based on steric exclusion chromatography for testing whether or not organics are chelated to radionuclides. 1 figure, 1 table.
