Biosorption of uranium and its effect on uranium transport in groundewater
… has been explored as a remediation method for uranium-contaminated groundwater at U.S. Department of Energy sites with promising results. Although transport models have been improved to include variations in geochemical concentrations, reductive microbial processes, and adsorption of uranium to …

URANYL DEPOSITION IN UNCONFORMITY-RELATED DEPOSITS IN THE ATHABASCA BASIN: EVIDENCE FROM URANIUM SPECIATION IN HEMATITE AND GOETHITE
… conditions, genetic models for the formation of uranium deposits had almost invariably invoked the pivotal roles of soluble U6+ species for the transport of uranium-bearing fluids and their reduction to sparingly soluble U4+ as the deposition mechanism. However, the questions of when and how this …

Basic studies for the incorporation of uranium in sediments
Uranium migration in natural aqueous systems is an ongoing concern in environmental research. Investigation on sorption interactions with soil, sediments and rocks are important to understand uranium mobility, in order to correct U/Th dating methods in open systems. Uranium immobilization is …

Origin of Uranium Mineralization at Coles Hill Virginia (USA) and its Natural Attenuation within an Oxidizing Rock-Soil-Ground Water System
… of a scientific basis for management of uranium bearing wastes and contaminants requires information from natural geologic systems. The following study of the Coles Hill uranium deposit and associated weathered zone constrains processes leading to the natural attenuation of uranium within …
