  • What is wetland mitigation banking?

    A mitigation bank is a wetland, stream, or other aquatic resource area that has been restored, established, enhanced, or (in certain circumstances) preserved for the purpose of providing compensation for unavoidable impacts to aquatic resources permitted under Section 404 or a similar state or local wetland regulation.  The concept has been around since the 1970’s.  In 1995 U.S. federal agencies ...

  • Supreme Court Weights In On Wetland Development

    Environmental Alert The Clean Water Act provides that "navigable waterways," or "waters of the United States," are subject to its provisions. Wetlands adjacent to "navigable waterways" are considered to be a "water of the United States" and are also within the jurisdiction of the Clean Water Act. The Army Corps of Engineers ("Corps"), the agency charged with administering the federal ...

  • Wetlands for Industrial Wastewater Treatment at the Savannah River Site

    ABSTRACT The A-01 effluent outfall, which collects both normal daily process flow and stormwater runoff from a industrial research facility, did not meet the South Carolina Department of Health and Environmental Control (SCDHEC) National Pollutant Discharge Elimination System (NPDES) permit limits for metals, toxicity, and total residual chlorine at the outfall sampling point. Copper was the ...

  • Evaluation of stormwater BMPs for implementing industrial stormwater permitting strategy

    This study assesses the performance of stormwater best management practices (BMPs) in industrial sectors and their effluent quality to facilitate the development of technology-based numerical effluent criteria. Generally, retention ponds outperform other BMP types for reducing total suspended solids, and media filter and wetland basins outperform other BMPs for metal removal. Detention basins ...

  • Design, Construction, and Startup of Sustainable and Integrated Wetlands Treatment Process in Stockton, California

    ABSTRACTConstructed treatment wetlands have become an established technology for treatment of municipal and industrial wastewaters around the world. Wetland systems can provide treatment similar to conventional tertiary wastewater facilities if sufficient land is available but with lower energy and maintenance requirements. Ancillary benefits of treatment wetlands include wildlife habitat, ...

  • Balancing Wetland Regulation with Stormwater Management on a Watershed-Wide Basis: A Case Study.

    Maryland reconciles rapid growth, water-quality goals, and habitat protection. In response to increasing regulatory authority over its water resources, the Maryland Department of the Environment (MDE) has combined various programs and processes into a 'one-stop shop' where various issues can be addressed in a uniform and consistent manner. As part of this process, onsite conditions are assessed, ...

  • Wetlands For Industrial Wastewater Treatment At The Savannah River Site: A Case Study

    ABSTRACT The A-01 effluent outfall, which collects both normal daily process flow and stormwater runoff from a industrial park-type area, did not meet the South Carolina Department of Health and Environmental Control (SCDHEC) National Pollutant Discharge Elimination System (NPDES) permit limits for metals, toxicity, and total residual chlorine at the outfall sampling point. However, copper is ...

  • Alum application to improve water quality in a municipal wastewater treatment wetland

    Received for publication January 18, 2008. Nutrient removal in treatment wetlands declines during winter months due to temperature. A 3-mo (wintertime) mesocosm study was conducted to determine the effectiveness of alum in immobilizing P as well as other nutrients during this period of reduced treatment efficiency. Eighteen mesocosms, triplicate alum, and three controls or no alum were ...

  • Frances Kelsey secondary school advanced wastewater treatment constructed wetland and effluent irrigation

    Location: Mill Bay, B.C. Owner: School District No. 65 Description: Site constraints necessitated a 75.6 m3/d treatment and disposal system to serve 1,200 students. The system includes septic tank, equalization tanks, advanced activated sludge treatment plant with nitrogen and phosphorous removal, constructed wetland, storage tank, ...

  • Wetland Biofilter System provides year-round, cost effective treatment to over 1.5 million litres of wastewater

    The success of early surface flow treatment wetlands in Canada was limited by hydraulic blockages and oxygen limitation due to freezing. From 1991 to 1996, Dr. Edgar Lemon, with the Friends of Fort George, researched a sub-surface vertical flow constructed wetland treating lagoon effluent at Niagara-on-the-Lake, funded by the Ontario Ministry of Environment (MOE) and the United States ...

  • Vegetated ditches for treatment of surface water with highly fluctuating water regime

    Vegetated drainage ditches (VDD) as a type of constructed wetland primarily serve to remove and store excess water associated with irrigation and storm events. Current research suggests using a VDD as an additional practice in the mitigation of surface water pollution. The VDD for water treatment of the Glinscica River was constructed in 2006. The efficiency of the system was evaluated in 2008 ...
