Download or read book Study of Environmental Effects of De icing Salt on Water Quality in the Twin Cities Metropolitan Area Minnesota written by Heinz G. Stefan and published by . This book was released on 2008 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to generate knowledge on the environmental effects of de-icing salt, particularly sodium chloride (NaCl), on water quality in Minnesota, especially the Twin Cities Metropolitan Area (TCMA). The Mississippi River receives substantial sodium chloride inputs from the Minnesota River and waste water treatment plants as it passes through the TCMA. In addition, road salt applications in the TCMA use about 350,000 short tons of NaCl every year. A chloride budget at the scale of the TCMA and on individual sub-watersheds in the TCMA indicates that about 70% of the road salt applied in the TCMA is not carried away by the Mississippi River. Rates of seasonal road salt use are correlated with snowfall, road miles and population. Salinity in TCMA lakes increases in winter and decreases in summer. Ionic composition of dissolved substances in lakes of the TCMA suggests unnaturally high sodium and chloride concentrations compared to lakes and other water bodies in the Midwestern U.S. Data indicate a rising trend in urban lake water salinity over the last 30 years. Shallow groundwater in the TCMA, especially near major roadways, has started to show increasing chloride concentrations. Salinity trends in lakes and shallow aquifers of the TCMA are of concern.

Book excerpt: Deicing agents for removal of ice and snow from highways and streets are essential to wintertime road maintenance in most areas of the U.S. Due to the ever-increasing use of highway deicing materials, there has been growing concern as to environmental effects resulting from these practices. The state-of-the-art report critically reviews the available information on methods, equipment and materials used for snow and ice removal; chlorides found in rainfall and municipal sewage during the winter; salt runoff from streets and highways; deicing compounds found in surface streams, public water supplies, groundwater, farm ponds and lakes; special additives incorporated into deicing agents; vehicular corrosion and deterioration of highway structures and pavements; and effects on roadside soils, vegetation and trees. Highway deicing can cause injury and damage across a wide environmental spectrum. Recommendations describe future research, development and demonstration efforts necessary to assess and reduce the adverse impact of highway deicing.

Download or read book Urban Climates written by T. R. Oke and published by Cambridge University Press. This book was released on 2017-09-14 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Climates is the first full synthesis of modern scientific and applied research on urban climates. The book begins with an outline of what constitutes an urban ecosystem. It develops a comprehensive terminology for the subject using scale and surface classification as key constructs. It explains the physical principles governing the creation of distinct urban climates, such as airflow around buildings, the heat island, precipitation modification and air pollution, and it then illustrates how this knowledge can be applied to moderate the undesirable consequences of urban development and help create more sustainable and resilient cities. With urban climate science now a fully-fledged field, this timely book fulfills the need to bring together the disparate parts of climate research on cities into a coherent framework. It is an ideal resource for students and researchers in fields such as climatology, urban hydrology, air quality, environmental engineering and urban design.
Download or read book Assessing and Managing the Ecological Impacts of Paved Roads written by National Research Council and published by National Academies Press. This book was released on 2006-01-22 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.

Download or read book The Ripple Effect written by Alex Prud'homme and published by Simon and Schuster. This book was released on 2011-06-07 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: AS ALEX PRUD’HOMME and his great-aunt Julia Child were completing their collaboration on her memoir, My Life in France, they began to talk about the French obsession with bottled water, which had finally spread to America. From this spark of interest, Prud’homme began what would become an ambitious quest to understand the evolving story of freshwater. What he found was shocking: as the climate warms and world population grows, demand for water has surged, but supplies of freshwater are static or dropping, and new threats to water quality appear every day. The Ripple Effect is Prud’homme’s vivid and engaging inquiry into the fate of freshwater in the twenty-first century. The questions he sought to answer were urgent: Will there be enough water to satisfy demand? What are the threats to its quality? What is the state of our water infrastructure—both the pipes that bring us freshwater and the levees that keep it out? How secure is our water supply from natural disasters and terrorist attacks? Can we create new sources for our water supply through scientific innovation? Is water a right like air or a commodity like oil—and who should control the tap? Will the wars of the twenty-first century be fought over water? Like Daniel Yergin’s classic The Prize: The Epic Quest for Oil, Money & Power, Prud’homme’s The Ripple Effect is a masterwork of investigation and dramatic narrative. With striking instincts for a revelatory story, Prud’homme introduces readers to an array of colorful, obsessive, brilliant—and sometimes shadowy—characters through whom these issues come alive. Prud’homme traversed the country, and he takes readers into the heart of the daily dramas that will determine the future of this essential resource—from the alleged murder of a water scientist in a New Jersey purification plant, to the epic confrontation between salmon fishermen and copper miners in Alaska, to the poisoning of Wisconsin wells, to the epidemic of intersex fish in the Chesapeake Bay, to the wars over fracking for natural gas. Michael Pollan has changed the way we think about the food we eat; Alex Prud’homme will change the way we think about the water we drink. Informative and provocative, The Ripple Effect is a major achievement.
