Speciation and structural characterization of Plutonium and Actinide-organic complexes in surface and ground waters

This report summarizes work after 3 years of the project. Activities so far included: 1) development and testing of sampling and analytical techniques for both actinides and organic constituents from natural waters, 2) confirmation of Pu and organic carbon concentrations, 3) field work at the Savannah River site (SRS) and at Hanford site (HS), and sample analysis, and 4) preparation of publications. While activities 1-2 have been summarized in prior reports, we are focusing on activity 3 in this report.
