Title: Speciation and structural characterization of Plutonium and Actinide-organic complexes in surface and ground waters (Sept. 1996-Sept. 1999) & Speciation, Mobility and Fate of Actinides in the Groundwater at the Hanford Site (Sept. 1999-Sept. 2002)

Abstract

Our first project focused on the development and testing of appropriate sampling and analytical techniques to study the association of actinides with dissolved organic complexes in subsurface waters. Our ongoing project is designed for: (1) the determination of the speciation of plutonium and other actinides (Np, U) in groundwater at the 100 and 200 areas at the Hanford Site. This includes the separation of Pu into particulate, colloidal and <1 kilo- Dalton dissolved phases and the determination of redox states and isotopic composition in each fraction; (2) the characterization of groundwater colloids, which includes submicron-sized inorganic particles and organic macromolecules (3) the prediction of the rate of transport and fate of actinides in the groundwater of the Hanford Site using a three-phase (dissolved-colloid-particulate) model.
