Electron donor and chlorinated ethene effects on activity and community composition in anaerobic reductively dechlorinating consortia

Creator:: Sabalowsky, Andrew R.
Abstract:: This research focused on anaerobic transformation of trichloroethene (TCE), a groundwater contaminant. The mixed anaerobic Evanite culture (EV) was studied to determine community behavior and composition responses to different electron donors and chloroethene electron acceptors. The potential toxicity from high concentrations of TCE and its daughter product cis-1,2-dichloroethene (cDCE) was...

Design and evaluation of a foundation model testing device

Creator:: Kelly, Patrick Bryan
Abstract:: Model testing has proven to be an effective tool in the study of soil-structure systems. While primarily used in research work, this method of evaluation is also applicable to the solution of many types of complex design problems. Because of its workability and relatively simple characteristics, sand is the most...

Radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface

Creator:: Davis, Brian M.
Abstract:: This study investigated the use of radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface. Laboratory physical aquifer models (PAMs), field experiments, and numerical simulations were used to investigate radon partitioning in static (no-flow) experiments and in single-well, 'push-pull' tests conducted in...

Inhibition, kinetic and modeling studies of acetylene and 1-chloro-1-fluoroethene on reductive dechlorination of TCE and vinyl chloride

Creator:: Pon, George
Abstract:: Laboratory and modeling studies were performed with a mixed-anaerobic-culture obtained from the Evanite site in Corvallis, Oregon. The culture completely transforms trichloroethene (TCE) to cis-dichloroethene (c-DCE), vinyl chloride (VC), and finally to ethene. Acetylene inhibition studies were used to examine the culture's microbial activities. Kinetic studies determined the half-saturated constant...

Aerobic biotransformation of chlorinated aliphatic hydrocarbons by a benzyl alcohol grown mixed culture : cometabolism, mechanisms, kinetics and modeling

Creator:: Tejasen, Sarun
Abstract:: The aerobic transformation of TCE and cis-DCE by a tetrabutoxysilane-grown microorganism (Vancheeswaran et al., 1999) led to the investigation of novel substrates, including benzyl alcohol, for promoting cometabolism. The culture grew on carboxylic compounds and alcohols, but did not grow on formate, methanol, methane, propane, butane, ethylene, benzene, toluene, or...

Kinetic and modeling investigations of the anaerobic reductive dechlorination of chlorinated ethylenes using single and binary mixed cultures and silicon-based organic compounds as slow-release substrates

Creator:: Yu, Seungho
Abstract:: This study investigated complete reductive dechlorination of chlorinated aliphatic hydrocarbons (CAHs) over a broad range of concentrations. Tetrabutoxysilane (TBOS), as a slow-release anaerobic substrate, was studied for enhanced reductive dechlorination of tetrachioroethylene (PCE) present as a dense non-aqueous liquid (DNAPL). Four different site-mixed cultures were used in the study: Site-300...
