  • Experience with Local Stormwater Management Programs

     ABSTRACT Local stormwater management programs have traditionally been operated and funded as a function of general government. Increasing requirements to deal with wet weather water quality problems and the devastating impact of flooding have led to increased efforts to expand organizational responsibilities and the need for new and dedicated funding. To provide a cross section of ...

  • Screening of organic contaminants in urban snow

    Snowmelt is known to cause peak concentrations of pollutants, which may adversely affect receiving water quality. High concentrations of metals and suspended solids in snow have been reported, whereas studies on organic pollutants are rare. This study aims at investigating the occurrence of anthropogenic organic compounds in urban snow in Gothenburg (Sweden). The most frequently detected organic ...

  • Micropollutants in stormwater runoff and combined sewer overflow in the Copenhagen area, Denmark

    Stormwater runoff contains a broad range of micropollutants. In Europe a number of these substances are regulated through the Water Framework Directive, which establishes Environmental Quality Standards (EQSs) for surface waters. Knowledge about discharge of these substances through stormwater runoff and combined sewer overflows (CSOs) is essential to ensure compliance with the EQSs. Results from ...

  • Structural improvements on hydrodynamic separators: a computational fluid dynamics approach

    Hydrodynamic separators (HDSs) have been used extensively to reduce stormwater pollutants from urbanized areas before entering the receiving water bodies. They primarily remove particulates and associated pollutants using gravity settling. Two types of HDSs with different structural configurations of the inner vortex-inducing components were presented in this study. One configuration consisted ...

  • Wire manufacturing facility - Case Study

    Bench-Scale Stormwater Treatment Study A large wire manufacturer in Washington State asked Dungeness Environmental to perform a treatability study on their stormwater run-off. The run-off requires remediation prior to discharge for turbidity, zinc, copper and lead concentrations. Dungeness performed an initial screening test in the lab simulating a variety of water treatment techniques for ...

  • Cities are the greatest hope for our planet

    If we design cities like ecosystems, they would have the potential to address many of our most pressing issues. Of all the things people build, cities are the most important. Cities are the largest things we build, and most people now live in them. But that’s not why cities are our most important invention. Cities matter because they ...

  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...
