Book excerpt: Highway stormwater runoff from large, multi-lane highways is one of the leading causes of watercourse impairment worldwide. Road runoff frequently carries within it a substantial physicochemical pollutant burden which includes sediments, nutrients, petroleum hydrocarbons and heavy metals. In seasonally-cold climates, winter maintenance activities entail the use of road salts, which constitute an additional source of pollutant loading to the road surface. A multi-pronged approach was used to improve the state of practice surrounding highway design, management and the methodological application of treatment approaches. First, a simple road salt application optimization tool was developed in order to help highway maintenance managers utilize a sound, scientifically defensible methodology when making determinations related to the frequency, timing and rate of road salt application. Data from three sites was used to modify the temperature index (TI) model to include sinusoidal variance in the daily melt coefficient, in addition to considerations related to the surficial rerouting of snow as well as the melt point depression caused by salt's interaction with snow and ice. The second avenue of investigation led to the development of artificial neural networks (ANNs) capable of predicting the runoff concentration statistical distribution parameters for common heavy metals (Cu, Zn, Cr, Pb) and total suspended solid (TSS) event mean concentrations (EMCs) within highway stormwater runoff. The third avenue of investigation focused on the assessment and testing of novel treatment media for the purpose of enhancing existing roadside ditches in environmentally sensitive areas (ESAs). Blast furnace (BF) slag, basic oxygenated furnace (BOF) slag, iron-enriched overburden (IRON) and wood chips (WC) were tested. The long-term removal of Cr, Co, Cu, Pb, Ni and Zn within repacked soil columns ranged from 46-98%. The fourth research effort focused on the development of a methodological framework for designing enhanced roadside ditch systems for application in ESAs. The feasibility of this framework is demonstrated through a field-scale pilot study, complemented by three years of real-time monitoring data. Three different types of impermeable liner - compacted clay (CC), high density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) - were tested for their ability to prevent stormwater egress from the facility.
Download or read book Cost effective and Sustainable Road Slope Stabilization and Erosion Control written by Laura Fay and published by Transportation Research Board. This book was released on 2012 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the United States it is estimated that 75 percent of all roads are low volume roads maintained by some 35,000 local agencies. Low volume roads often omit surface slope protection, and this can lead to slope failure, erosion, and maintenance, safety, and ecological issues. This report presents information on cost effective and sustainable road slope stabilization techniques, with a focus on shallow or near surface slope stabilization and related erosion control methods used on low volume roads. To fully address this topic, planning and site investigation are discussed, as well as erosion control techniques, soil bioengineering and biotechnical techniques, mechanical stabilization, and earthwork techniques. Information presented in this report was obtained through an extensive literature review, and from survey and interview responses. From the survey responses, 30 individuals were interviewed based on the information they made available in the survey. A total of 25 interviews were conducted over the phone, and in two cases written responses were received"--Preface.
Download or read book Mycelium Running written by Paul Stamets and published by Ten Speed Press. This book was released on 2011-03-09 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycelium Running is a manual for the mycological rescue of the planet. That’s right: growing more mushrooms may be the best thing we can do to save the environment, and in this groundbreaking text from mushroom expert Paul Stamets, you’ll find out how. The basic science goes like this: Microscopic cells called “mycelium”--the fruit of which are mushrooms--recycle carbon, nitrogen, and other essential elements as they break down plant and animal debris in the creation of rich new soil. What Stamets has discovered is that we can capitalize on mycelium’s digestive power and target it to decompose toxic wastes and pollutants (mycoremediation), catch and reduce silt from streambeds and pathogens from agricultural watersheds (mycofiltration), control insect populations (mycopesticides), and generally enhance the health of our forests and gardens (mycoforestry and myco-gardening). In this comprehensive guide, you’ll find chapters detailing each of these four exciting branches of what Stamets has coined “mycorestoration,” as well as chapters on the medicinal and nutritional properties of mushrooms, inoculation methods, log and stump culture, and species selection for various environmental purposes. Heavily referenced and beautifully illustrated, this book is destined to be a classic reference for bemushroomed generations to come.

Available in PDF, EPUB and Kindle. Book excerpt: Although initially based purely on environmental principles of reuse and recycling, natural waste treatment systems proved to have economic advantages over mechanical systems in many cases, being less expensive to build and operate as well as requiring less energy. Thus, natural waste treatment methods reemerged even as advanced wastewater treatmen
Download or read book Post fire Treatment Effectiveness for Hillslope Stabilization written by Peter R. Robichaud and published by . This book was released on 1998 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis of post-fire treatment effectiveness reviews the past decade of research, monitoring, and product development related to post-fire hillslope emergency stabilization treatments, including erosion barriers, mulching, chemical soil treatments, and combinations of these treatments. In the past ten years, erosion barrier treatments (contour-felled logs and straw wattles) have declined in use and are now rarely applied as a post-fire hillslope treatment. In contrast, dry mulch treatments (agricultural straw, wood strands, wood shreds, etc.) have quickly gained acceptance as effective, though somewhat expensive, post-fire hillslope stabilization treatments and are frequently recommended when values-at-risk warrant protection. This change has been motivated by research that shows the proportion of exposed mineral soil (or conversely, the proportion of ground cover) to be the primary treatment factor controlling post-fire hillslope erosion. Erosion barrier treatments provide little ground cover and have been shown to be less effective than mulch, especially during short-duration, high intensity rainfall events. In addition, innovative options for producing and applying mulch materials have adapted these materials for use on large burned areas that are inaccessible by road. Although longer-term studies on mulch treatment effectiveness are on-going, early results and short-term studies have shown that dry mulches can be highly effective in reducing post-fire runoff and erosion. Hydromulches have been used after some fires, but they have been less effective than dry mulches in stabilizing burned hillslopes and generally decompose or degrade within a year.

Download or read book Natural Wastewater Treatment Systems Second Edition written by Ronald W. Crites and published by CRC Press. This book was released on 2014-03-14 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calling for ecologically and economically sound wastewater treatment systems, the authors of Natural Wastewater Treatment Systems explore the use of wetlands, sprinkler or deep irrigation, groundwater recharge, and other natural systems as sustainable methods for the treatment and management of wastewater. Based on work by prominent experts in natural waste treatment, this text provides a thorough explanation on how soil and plants can successfully sustain microbial populations in the treatment of wastewater. Determining that natural systems cost less to construct and operate, and require less energy than mechanical treatment alternatives, this book also explains how these processes produce lower amounts of residual solids, and use little or no chemicals. What’s New in the Second Edition: This revised edition includes current design and regulatory and operational developments in the natural wastewater treatment field. It provides detailed examples and analyses along with significant operational data in each chapter. It also considers how processes provide passive treatment with a minimum of mechanical elements, and describes new approaches to partially mixed ponds, including dual-powered aeration ponds. Introduces the planning procedures and treatment mechanisms responsible for treatment in ponds, wetlands, land application, and soil absorption systems Provides new case studies of constructed wetlands and water reuse systems Presents design criteria and methods of pond treatment and pond effluent upgrading Describes constructed wetlands design procedures, process applications, treatment performance data, and land treatment concepts and design equations Includes information on constituents of emerging concern (CEC) and their fate in natural systems The text discusses wastewater pond systems, free water surface constructed wetlands, subsurface and vertical flow constructed wetlands, land treatment, sludge management, and onsite wastewater systems. It describes residuals and biosolids management, including nitrogen removal pretreatment methods, and uses U.S. customary and metric units in all chapters. It presents case studies of new applications of natural systems and includes worked examples of design equations for ponds and land treatment. It also provides a biosolids regulatory update from a top EPA scientist, and algae reduction technologies for ponds and wetlands. Designed for practicing wastewater engineers and scientists involved in the planning, design, and operation of ponds, wetlands, land treatment, biosolids, and onsite soil-based treatment systems, the book integrates many natural treatment systems into one single source.

This book was released on 1988 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides interim guidelines for the design of management measures for the removal of pollutants from highway stormwater runoff. Three general types of management measures have been determined, through previous FHWA studies, to be effective in treating highway runoff: vegetative controls (overland flow and grassed channels), detention basins (wet detention basins and wetlands), and retention measures (retention basins, trenches and wells). These interim design guidelines have been developed based on experience of the project team and by a thorough review of available literature. Field and laboratory studies are currently underway to verify the design procedures and assumptions presented in this report.
