Some of the nation's estuaries, lakes and other water bodies contain contaminated sediments that can adversely affect fish and wildlife and may then find their way into people's diets. Dredging is one of the few options available for attempting to clean up contaminated sediments, but it can uncover and re-suspend buried contaminants, creating additional exposures for wildlife and people. At the request of Congress, EPA asked the National Research Council (NRC) to evaluate dredging as a cleanup technique. The book finds that, based on a review of available evidence, dredging's ability to decrease environmental and health risks is still an open question. Analysis of pre-dredging and post-dredging at about 20 sites found a wide range of outcomes in terms of surface sediment concentrations of contaminants: some sites showed increases, some no change, and some decreases in concentrations. Evaluating the potential long-term benefits of dredging will require that the U.S. Environmental Protection Agency step up monitoring activities before, during and after individual cleanups to determine whether it is working there and what combinations of techniques are most effective.

In this text, drawn from presentations and discussion at a May 2005 NATO Advanced Research Workshop, current approaches to the assessment and remediation of contaminated sediments are discussed with emphasis on in-situ management. The text addresses physical, chemical and biological approaches for the assessment and remediation of sediments. The development of regulatory and strategic approaches is discussed with emphasis on the potential for biological remediation in the management of contaminated sediments.

In the early nineteenth century, a naturalist named Rafinesque stood on the banks of the Ohio River and began to describe the freshwater mussels he found there. Since that time, these animals have earned a place among the most imperiled animals in North America. Dozens of species have become extinct, and it is estimated that two-thirds of the remaining freshwater mussels face a similar fate. Yet, despite their importance, the mussels of Ohio remain a poorly documented and largely mysterious fauna. This book compiles existing research on Ohio's mussels, synthesizing works on genetics, biology, and systematics into one volume. Full-page color images depict shell variation, hinge detail, and beak sculpture. Full-page maps show the distribution of each species based upon the collections of numerous museums, with historical distributions dating from the 1800s. In addition to species accounts, the book has an introductory section that includes information on basic biology, human use, and conservation issues.--adapted from jacket.

As ecology becomes the new engineering, the projection of landscape as infrastructure—the contemporary alignment of the disciplines of landscape architecture, civil engineering, and urban planning— has become pressing. Predominant challenges facing urban regions and territories today—including shifting climates, material flows, and population mobilities, are addressed and strategized here. Responding to the under-performance of master planning and over-exertion of technological systems at the end of twentieth century, this book argues for the strategic design of "infrastructural ecologies," describing a synthetic landscape of living, biophysical systems that operate as urban infrastructures to shape and direct the future of urban economies and cultures into the 21st century. Pierre Bélanger is Associate Professor of Landscape Architecture and Co-Director of the Master in Design Studies Program at Harvard University’s Graduate School of Design. As part of the Department of Landscape Architecture and the Advansed Studies Program, Bélanger teaches and coordinates graduate courses on the convergence of ecology, infrastructure and urbanism in the interrelated fields of design, planning and engineering. Dr. Bélanger is author of the 35th edition of the Pamphlet Architecture Series from Princeton Architectural Press, GOING LIVE: from States to Systems (pa35.net), co-editor with Jennifer Sigler of the 39th issue of Harvard Design Magazine, Wet Matter, and co-author of the forthcoming volume ECOLOGIES OF POWER: Mapping Military Geographies & Logistical Landscapes of the U.S. Department of Defense. As a landscape architect and urbanist, he is the recipient of the 2008 Canada Prix de Rome in Architecture and the Curator for the Canada Pavilion ad Canadian Exhibition, "EXTRACTION," at the 2016 Venice Architecture Biennale (extraction.ca).

The biological, radiological, chemical and physical traits of water are known as water quality. It is a measure of the water condition related to the requirements of biotic species and to human need. The health of ecosystems, safety of human contact, and drinking water are the most common standards used to measure water quality. Water quality parameters can be categorized into human consumption, environmental water quality, and industrial and domestic use. The measurement of water quality includes the process of sample collection, chemical analysis, real-time monitoring and testing in response to natural disasters. Various environmental indicators such as physical, chemical and biological indicators are also observed and used for the monitoring of water quality. This book explores all the important aspects of water quality in the present day scenario. It elucidates new techniques and their applications in a multidisciplinary manner. It will prove to be immensely beneficial to students and researchers in this field.

Winston Churchill, whose output as a writer was so prodigious that one might reasonably wonder whether he was paid by the page, was him self put off by long works. As prime minister of Great Britain, he once pushed away a report from a junior minister, observing, "This paper, by its very length, defends itself against the risk of being read." No doubt some laymen will glance at the study that follows and be deterred from further consideration by the fact that the study is a scien tific one. If that is a hurdle for you, I hope you will join me in getting over it, because, if you do, you will find that the authors have quite a story to tell. That story is about change-the possibility that the climatic patterns of the world are in a transition to warmer weather that could lead to a rise in the sea level. You may not have thought much about the sea level previously; it was something we took for granted. But since we have taken it as a given for so long, the adjustments we may have to make will be profound. When you stop to think about all the areas of our lives that could be affected by climatic change, you will be amazed: we have planned our cities, developed our manufacturing techniques, and chosen our en vironmental protection strategies on the assumption of a stable seaJevel.
