Acceleration of Field-Scale Bioreduction of U(VI) in a Shallow Alluvial Aquifer: Temporal and Spatial Evolution of Biogeochemistry
Uranium mill tailings sites provide access to uranium-contaminated groundwater at sites that are shallow and low hazard, making it possible to address the following scientific objectives: (1) Determine the dominant electron accepting processes at field sites with long-term metal/rad contamination; (2) Define the biogeochemical transformations that may be important to either natural or accelerated bioremediation under field conditions; and (3) Examine the potential for using biostimulation (electron donor addition) to accelerate reduction of U(VI) to U(IV) at the field scale.

Bacterial Biotransformations for the In situ Stabilization of Plutonium
Plutonium contamination in the environment is generally low-level and may be present and transported in a range of forms (IV, V, VI). Current remediation strategies are costly, financially and in terms of increased exposure risk to people and the environment. In situ bacterial biostabilization is a promising alternative.

Comparative biochemistry and physiology of metal-reducing organisms from acidic and neutral pH environments
Comparison of the metal reduction efforts between a sampled acidophile alphaprotebacteria (Acidiphilium cryptum JF-5) and a neutrophile deltaprotebacteria (Geobacter spp.), for the purposes of discovering if the two samples reduce metal with similar structured organelles.

Reoxidation of Bioreduced Uranium Under Reducing Conditions
Stimulation of U(VI) bioreduction is becoming an attractive in-situ method for stabilizing U in contaminated sediments. After reduction of U(VI) is completed in sediments, how stable is bioreduced U(IV) upon exposure to oxidizing groundwaters?
