Field Microcosms. Abstract approved: Lewis Semprini The cometabolism of 1,1,1- tiichloroethane (1,1,1
Bench-scale study for the bioremediation of chlorinated ethylenes at Point Mugu Naval Air Weapons Station, Point Mugu California, IRP Site 24

Creator:

Keeling, Matthew Thomas

Abstract:

Laboratory scale microcosm studies were conducted using site specific groundwater and aquifer solids to assess the feasibility of stimulating indigenous microorganisms in-situ to biologically transform Trichloroethylene (TCE) and its lesser chlorinated daughter products dichloroethylene (DCE) and vinyl chloride (VC). Three different treatments were conducted to determine the best approach for...

An anaerobic microcosm study of TCE transformation by microbes stimulated from the Gilbert-Mosley site, Wichita, Kansas

Creator:

Pon, George

Abstract:

A mix-culture of methanogenic and sulfate-reducing bacteria was capable of degrading trichloroethylene (TCE) to dichloroethylene (DCE). The culture was incubated under anaerobic conditions within a soil sample taken from Gilbert-Mosley site, Wichita, Kansas. To stimulate the growth of indigenous bacteria, a carbon and energy source was added in this microcosm...

Radon-222 as an indicator for nonaqueous phase liquids in the saturated zone : developing a detection technology

Creator:

Hopkins, Omar Snowden

Abstract:

Radon-222 gas has unique properties allowing it to be used as an indicator for the presence of organic phase liquids in the saturated zone. It naturally occurs in soils. It is radioactive, making quantitative detection straight forward. A noble gas, it is chemically inert and does not react with aquifer...

Aerobic cometabolism of chloroform by butane and propane grown microorganisms from the Hanford subsurface

Creator:

Kim, Young

Abstract:

Batch microcosm studies were carried out to screen for microorganisms from the subsurface of Hanford DOE site that could cometabolically transform chloroform (CF) under aerobic conditions. The potential need for CF bioremediation at the Hanford site has resulted from the large release of carbon tetrachloride (CT) to the subsurface, of...

Continuous-flow and batch column studies of anaerobic carbon tetrachloride biotransformation on Hanford soil

Creator:

Niemet, Michael Richard

Abstract:

Continuous-flow and batch experiments were conducted with a column reactor system containing Hanford aquifer material in order to evaluate the potential of in-situ bioremediation of carbon tetrachloride (CT) at Hanford. The effectiveness of benzoate and acetate as primary substrates was considered. Nitrate and sulfate were potential electron acceptors. Transport experiments...

Radon-222 as a tracer for performance assessment of NAPL remediation technologies in the saturated zone : an experimental investigation

Creator:

Gottipati, Sarayu

Abstract:

Persistence of Non aqueous phase liquids (NAPLs) in the subsurface at residual saturations eventually contributes to undesirable groundwater contamination. Proper characterization of subsurface NAPL, its location, composition and distribution, is essential for the chosen remediation technology to be effective. It is also desirable to assess the performance of remedial actions...
