Anaerobic reductive dechlorination of TCE and TCFE in TCE contaminated sediments : enhanced bioremediation and bioaugmentation

Creator:

Lee, Jae-Hyuk

Abstract:

This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...

Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

Creator:

Michalsen, Mandy M.

Abstract:

Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...
