Experimental design of physical aquifer models for evaluation of groundwater remediation strategies

Creator:: Humphrey, Mark D.
Abstract:: Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...

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...

Demonstration of a permeable barrier technology for the in-situ bioremediation of pentachlorophenol contaminated groundwater

Creator:: Cole, Jason David
Abstract:: A pilot scale demonstration of a biological permeable barrier was conducted in a pentachlorophenol-contaminated aquifer at a wood preserving facility. A permeable reactor was constructed to fit within a large diameter well. Arranged in series, a cylindrical reactor 24" x 36" (0.61 x 0.91m) (diameter x height) was partitioned to...

Down-borehole permeable barrier reactor : primary substrate selection for aerobic dichlorophenol degradation

Creator:: Kaslik, Peter J.
Abstract:: In situ bioremediation of pentachlorophenol-contaminated ground water in a sequential anaerobic-aerobic down borehole permeable barrier reactor requires a non-toxic primary substrate for dichlorophenol cometabolism. Serum bottle tests comparing the effectiveness of eight primary substrates for aerobic dichlorophenol degradation showed phenol to be the most effective followed by imitation vanilla flavoring,...

Uranium and technetium bio-immobilization in intermediate-scale permeable reactive scale barriers

Creator:: Sapp, Mandy M.
Abstract:: Groundwater at Oak Ridge National Laboratory's Field Research Center (FRC) is contaminated with U(VI) and Tc(VII), has pH values as low as 3.3, and nitrate concentrations as high as 120 mM. The objective of this research was to determine if in-situ bio-immobilization is a viable treatment alternative for this water....

Aerobic cometabolism of 1,1,1-trichloroethane and 1,1-dichloroethene by a bioaugmented butane-utilizing culture in a continuous flow column

Creator:: Maremanda, Bhargavi
Abstract:: The transformation of 1,1,1 -trichioroethane (1,1,1 -TCA) and 1,1 -dichioroethene (1,1 - DCE) was evaluated in a continuous flow column reactor using a mixed culture that grew on butane. The column was packed with aquifer materials and groundwater obtained from the in-situ bioremediation test site at Moffett Field, CA. The...

Construction of a model organism for performing calcium carbonate precipitation in a porous media reactor

Creator:: Kaufman, Megan J.
Abstract:: Aquifers are an important storage location and source of fresh groundwater. They may become polluted by a number of contaminants including mobile divalent radionuclides such as strontium-90 which is a byproduct of uranium fission. A method for remediating such divalent radionuclides is sequestration through co-precipitation into calcium carbonate. Calcium carbonate...
