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...

Quantification of advection and dispersion in lateral subsurface flowpaths at the hillslope-scale

Creator:: Victory, Nichole I.
Abstract:: It is becoming increasingly important to understand fundamental hillslope-scale hydrological processes. Most hillslope-sale transport experiments have generally focused on conceptual findings or other aspect of flow behavior, rather than the quantification of the mass transport mechanisms of advection and dispersion. When the velocities have been quantified, dispersion has been mentioned...

A kinetic model for dissolved gas transport in the presence of trapped gas

Creator:: Donaldson, Jeremy H.
Abstract:: Understanding the processes involved in the transport of dissolved gas plumes in groundwater aquifers is essential for comprehending the effect that these transport processes can have on site characterization and remedial design applications. Previous laboratory and field studies have indicated that dissolved gas transport in groundwater can be greatly affected...

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....

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...

Reliability-based Serviceability Limit State Design Procedures for Shallow Foundations

Creator:: Huffman, Jonathan C.
Abstract:: Reliability-based geotechnical foundation design focusses on soil and structure analysis that meets necessary safety, performance and/or serviceability criteria, calibrated based on probabilistic analyses and an accepted level of risk. As the civil engineering community seeks to better harmonize geotechnical and structural design methodologies, reliability-based design is being incorporated more into...

Effect of electron donors on the reductive dechlorination of trichlorofluoroethylene in anaerobic microcosms and in situ push-pull tests

Creator:: Louie, Erika N.
Abstract:: This research focuses on the anaerobic transformation of trichloroethylene (TCE) that is occurring in the subsurface of the Evanite site in Corvallis, OR. Two anaerobic studies were conducted to investigate the effects of microbial communities in the presence of different electron donors during the anaerobic degradation of trichlorofluoroethylene (TCFE), and...

Fate of THMs in Columbia River basalts during aquifer storage and recovery

Creator:: Bertrand, Danelle
Abstract:: Use of basalt aquifers for aquifer storage and recovery (ASR) systems is increasing in the Pacific Northwest due to the large aerial extent of the Columbia River Basalt Group and the suitability of basalts as ASR reservoirs. However, the degradation of trihalomethanes (THMs), potentially carcinogenic disinfection by-products present in the...

Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

Creator:: Mustafa, Nizar Ahmad
Abstract:: Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...
