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...

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...

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 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...

Abiotic and biological transformation of TBOS and TKEBS, and their role in the biological transformation of TCE and c-DCE

Creator:: Vancheeswaran, Sanjay
Abstract:: At Site-300, Lawrence Livermore National Laboratory (LLNL), CA, trichloroethene (TCE) is present along with tetraalkoxysilanes such as tetrabutoxysilane (TBOS) and tetrakis(2-ethylbutoxy) silane (TKEBS), as subsurface contaminants. Intrinsic transformation of TCE to cis-dichloroethene (c-DCE) was observed in the groundwater at locations co-contaminated with TBOS or TKEBS. Attenuation of TBOS and TKEBS...

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...

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...
