Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of research to evaluate the potential of utilizing mitigated wetlands as stormwater Best Management Practices (BMPs). Results of wetland monitoring, wetland modeling, and geographic information system (GIS) development are presented. Average removal rates as high as 90% for total suspended solids (TSS), 65% for chemical oxygen demand (COD), 70% for total phosphorus (TP) and orthophosphate (OP), and 50% for zinc (Zn) were observed at study sites. Despite having stormwater runoff as a primary water source, the monitored sites supported apparently healthy and diverse vegetation, and a variety of wildlife. A mathematical model of transport of a pollutant in dissolved and particulate forms in a two segment, two-state system was developed. The model includes settling, diffusion, adsorption to plant and substrate, and vegetative uptake mechanisms. A GIS was developed to improve management of existing mitigated wetlands and to aid in siting of future mitigation sites. A link between a watershed model and this GIS is also described. The report concludes that mitigated wetlands may be as effective as conventional BMPs at improving the quality and at controlling the quantity of highway storm runoff.

Available in PDF, EPUB and Kindle. Book excerpt: Both practical and theoretical, this book provides the basic principles of soil chemistry, hydrology, wetland ecology, microbiology, vegetation and wildlife as a sound introduction to this innovative technology to treat toxic wastewaters and sludges. The use of wetlands for acid mine drainage, and metals removal in municipal, urban runoff, and industrial systems is discussed. Case histories are also presented, demonstrating specific types of constructed wetlands and applications to municipal wastewater, home sites, coal and non-coal mining, coal-fired electric power plants, chemical and pulp industry, agriculture, landfill leachate, and urban stormwater. Construction and management guidelines are clearly explained, providing information on applicable policies and regulations, siting and construction, and operations and monitoring of constructed wetlands treatment systems. Recent theoretical and empirical results from operating systems and research facilities, including such new applications as nutrient removal from eutrophic lakes and urban stormwater treatment within highway rights-of-way, are included.

Available in PDF, EPUB and Kindle. Book excerpt: Wetland Systems to Control Urban Runoff integrates natural and constructed wetlands, and sustainable drainage techniques into traditional water and wastewater systems used to treat surface runoff and associated diffuse pollution. The first part of the text introduces the fundamentals of water quality management, and water and wastewater treatment. The remaining focus of the text is on reviewing treatment technologies, disinfection issues, sludge treatment and disposal options, and current case studies related to constructed wetlands applied for runoff and diffuse pollution treatment. Professionals and students will be interested in the detailed design, operation, management, process control and water quality monitoring and applied modeling issues. * Contains a comprehensive collection of timely, novel and innovative research case studies in the area of wetland systems applied for the treatment of urban runoff * Demonstrates to practitioners how natural and constructed wetland systems can be integrated into traditional wastewater systems, which are predominantly applied for the treatment of surface runoff and diffuse pollution * Assesses the design, operation, management and water treatment performance of sustainable urban drainage systems including constructed wetlands

Available in PDF, EPUB and Kindle. Book excerpt: Wetland mitigation and stormwater management provisions in the 1987 Clean Water Act (CWA) significantly impact transportation agencies. CWA Section 404 stipulates that when highway construction results in the displacement of natural wetlands, the highway agency is required to create artificial wetlands to compensate for that loss. Section 402 directs the U.S. Environmental Protection Agency (EPA) to regulate stormwater runoff from certain areas under the National Pollutant Discharge Elimination System (NPDES). Highway stormwater runoff, runoff from road construction sites with five or more disturbed acres, and runoff from maintenance and storage facilities are subject to NPDES permit requirements. In addition to the EPA regulations, the Virginia Department of Transportation (VDOT) must also comply with the Chesapeake Bay Preservation Act, Virginia's Stormwater Management Regulations, and State Erosion and Sediment Control Regulations. A common requirement of all of these stormwater regulations is the use of best management practices (BMP), such as detention ponds and infiltration for the control of runoff quantity and quality. To date, VDOT has constructed over 220 wetlands and more than 350 stormwater detention basins. Wetland mitigation is a significant item in the VDOT road-building budget. Compliance with applicable stormwater regulations can add between ten and fifteen percent to the cost of an average construction project. A potentially cost-effective approach to satisfying wetland mitigation requirements and stormwater regulations is the use of mitigated wetlands as stormwater BMPs. It is believed that if a mitigated wetland site is properly engineered and maintained, it will perform adequately as a stormwater BMP without jeopardizing its desired wetland functions. It may also be possible to design a detention basin to include emergent wetland vegetation to enhance pollutant removal.

Download or read book Ecotechnologies for the Treatment of Variable Stormwater and Wastewater Flows written by Katharina Tondera and published by Springer. This book was released on 2017-11-15 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an essential overview of ecotechnologies (also known as green infrastructure or nature-based solutions) which are considered to be relatively resilient to variations in stormwater and wastewater inflow. In particular, it focuses on various types of constructed wetlands, biofilters and ponds. Stormwater flows are inherently variable, due to rainfall events and fluctuations in loading. This variability has significant effects on the performance of treatment systems, but has rarely been specifically addressed in design manuals, performance assessments or modelling. The book’s respective chapters cover the main contaminant categories of interest (nutrients, faecal microbes, metals and emerging contaminants) and their removal processes using ecotechnologies, addressing urban, industrial and agricultural applications. In addition, they review modelling tools with the potential to improve our understanding of flow variability and the ability to simulate and predict responses to it.

This book was released on 2001-01-01 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide examines permanent structural techniques, or Best Management Practices (BMPs), which can be used for retrofitting the stormwater management systems in existing developed areas. The advantages and disadvantages of each technique are explained to help engineering professionals select the BMP (or series of BMPs) best suited for removing pollutants from stormwater runoff at a particular location. The design factors considered include land availability, type of pollutant to be removed, groundwater levels, soil types, BMP costs, maintenance costs, and desired pollutant removal efficiency. The BMPs evaluated are ponds, alum treatment systems, constructed wetlands, sand filters, baffle boxes, inlet devices, vegetated swales, buffer strips, and infiltration/exfiltration trenches. A BMP Selection Guide, in an easy-to-use matrix format, aids in the decision-making process for BMP selections. Five design factors and five pollutant types (total suspended solids, total phosphorus, total nitrogen, heavy metals, and floating trash) are evaluated for each BMP in the matrix. BMPs presented in this guide were chosen based upon common availability, ease of maintenance, and an established track record.
