  • Determination of fluorinated alkyl substances in aqueous systems

    Creator:
    Schultz, Melissa M.
    Abstract:
    Fluorinated alkyl substances, which can be persistent, toxic, and bioaccumulative, have been quantitated in many densely populated and remote regions, including in air, surface waters, groundwater, and biota; however, little is known about their transport or behavior in the environment. Wastewater effluent is one of the principal routes for introducing...

  • Determination of fluorochemicals in waste-dominated aqueous systems

    Creator:
    Huset, Carin A.
    Abstract:
    While fluorochemicals have been detected all over the world and in wastewater treatment plants, the effect of wastewater effluent on the receiving waters has not been evaluated. In the first study, the mass flow of fluorochemicals emanating from wastewater treatment plants along the Glatt River in Switzerland was evaluated. The...

  • Essays of Land Use Changes, Open Space, and Water Pollution

    Creator:
    Hagimoto, Toru
    Abstract:
    Land use is one of the leading factors that cause environmental degradation, such as water pollution, open space contraction and habitat loss. This dissertation consists of three essays. First paper investigates the relationship between land use and water pollution. Combining land use choice model and water pollution data, I simulate...

  • Antimicrobial contaminant removal by multi-stage drinking water filtration

    Creator:
    Rooklidge, Stephen J.
    Abstract:
    The fate of antimicrobials entering the aquatic environment is an increasing concern for researchers and regulators, and recent research has focused on antimicrobial contamination from point sources, such as wastewater treatment facility outfalls. The terraccumulation of antimicrobials and mobility in diffuse pollution pathways should not be overlooked as a contributor...

  • 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...
