Summary
Through the use of core columns we have demonstrated the potential for the release of low-levels of Pu from contaminated saturated zone soils. Transport of the reduced species of Pu occurs as both dissolved (soluble plus colloidal) species and as particulates. The colloidal plus particulate species account for 50 to 70 % of the total Pu released under our oxidizing conditions. The mechanisms for release of soluble versus colloidal plus particulate species appear to be different with bacterial involvement in the release of the latter species being highly probable.
