  • Copper Speciation in Wastewater-Impacted Surface Waters

    Creator:
    Mosbrucker, Ariel M.
    Abstract:
    This study investigates the relationship between total and ionic copper in samples taken from the Tualatin River and wastewater treatment facilities (WWTFs) that discharge into the Tualatin River. Copper speciation was analyzed by determining conditional stability constants and densities of copper binding ligands on the dissolved organic matter (DOM) in...

  • Evaluation of copper removal from stormwater runoff using compost and Apatite II™

    Creator:
    Silvertooth, Jason R.
    Abstract:
    Low concentrations of dissolved copper have proven to be harmful to a number of aquatic organisms, with recent research highlighting detrimental effects to endangered salmonid species. Stormwater runoff can represent a significant source of copper to surface waters, necessitating cost-effective alternatives to current stormwater best management practices (BMPs). This study...

  • Evaluation of Apatite II™ for removal of copper and zinc from highway stormwater runoff : laboratory and field experiments

    Creator:
    Provolt, Justin J.
    Abstract:
    Current best management practices (BMPs) for stormwater treatment are not able to adequately remove heavy metals to levels which do not adversely affect aquatic life. Copper is commonly found in highway stormwater runoff, with the primary source being brake pad wear. Copper is of particular concern due to inhibitory effects...
