  • The role of iron-oxides in U(VI) adsorption and the kinetics of contaminant organic reduction

    Creator:
    Logue, Brian A.
    Abstract:
    Contaminant transport in ground water is an important environmental process that affects a host of natural systems. Transport of contaminants is affected by many processes, including aqueous complexation, adsorption, and redox reactions. One of the most important components of an aquifer that controls transport is iron-oxide. In this study, the...

  • Measuring in situ reductive dechlorination rates in trichloroethene-contaminated groundwater

    Creator:
    Hageman, Kimberly J.
    Abstract:
    Trichloroethene (TCE) is the most frequently detected organic contaminant in groundwater, is classified as a probable human carcinogen, and exhibits toxicological effects on the human endocrine, immune, developmental, and reproductive systems. While significant research efforts have been devoted to the development of strategies for remediating TCE-contaminated groundwater, their advancement is...

  • Fate and transport of the surfactant linear alkylbenzenesulfonate in a sewage-contaminated aquifer

    Creator:
    Krueger, Carolyn J.
    Abstract:
    Linear alkylbenzenesulfonate (LAS) is the most widely used anionic surfactant in commercial detergent formulations. The environmental fate of LAS is of interest because of its disposal to wastewater treatment facilities and subsequent occurrence as a micropollutant in surface waters and groundwater. While LAS fate in wastewater treatment systems and surface...

  • In situ transformation of toluene and xylene to benzylsuccinic acid analogs in contaminated groundwater

    Creator:
    Reusser, Dominik E.
    Abstract:
    The rate of removal of benzene, toluene, ethylbenzene and the xylene isomers (BTEX) from contaminated groundwater is needed to design remediation processes. Benzylsuccinic acid (BSA) and methyl-benzylsuccinic acid (methyl BSA) are unambiguous metabolites of anaerobic BTEX biodegradation. An analytical method for quantitative determination of BSA in groundwater samples was developed....
