The Third National Conference on Environmental Science and Technology was held in Greensboro, NC, on September 12-14, 2007. This book contains the following topics: pollution prevention, fate and transport of contaminants, bioremediation, bio-processing, innovative environmental technologies, global climate change, and environmental justice.

What is Riverbank Filtration? The purpose ofthis book is to show that riverbank filtration (RBF) isa low-cost and efficient alternative water treatment for drinking-water applications. There are two immediate benefits to the increased use of RBF: Minimized need for adding chemicals like disinfectants and coagulants to surface water to control pathogens. Decreased costs to the community without increased risk to human health. Butwhat,exactly, isRBF? In humid regions, river water naturally percolates through the ground into aquifers (which are layers of sand and gravel that contain water underground) during high-flow conditions. In arid regions, most rivers lose flow, and the percolating water passes through soil and aquifer material until it reaches the water table. During these percolation processes, potential contaminants present in river water are filtered and attenuated. If there are no other contaminants present in the aquifer or ifthe respective contaminants are present at lower concentrations, the quality of water in the aquifer can be ofhigher quality than that found in theriver. In RBF, production wells — which are placed near the banks ofrivers —pump large quantities ofwater.
"With clarity and grace, Stephen Bocking tackles the complicated question of the role of scientific expertise in environmental policy making. Nature’s Experts is a timely and important book."—David H. Guston, author of Between Politics and Science: Assuring the Integrity and Productivity of Research "This book by Stephen Bocking is as much about deliberative democracy as it is about science and the environment. Stephen Bocking’s treatment is deep, perceptive, and profoundly wise. He has caught the heart of present and future environmental science, politics, and democratic governance."—C. S. Holling, The Resilience Alliance and emeritus professor, Arthur R. Marshall Jr. Chair in Ecological Sciences at the University of Florida "If knowledge is power, how should expert advice be deployed by a would-be democratic society? This perennial question is newly illuminated by this timely and wide-ranging review of the role played by science in the making of environmental policy."—William C. Clark, Harvey Brooks Professor of International Science, Public Policy, and Human Development, Harvard University, John F. Kennedy School of Government It seems self-evident that science plays a central role in environmental affairs. Regulatory agencies, businesses, and public interest groups all draw on scientific research to support their claims. Some critics, however, describe science not as the solution to environmental problems, but as their source. Moreover, the science itself is often controversial, as debates over global warming and environmental health risks have shown. Nature’s Experts explores the contributions and challenges presented when scientific authority enters the realm of environmental affairs. Stephen Bocking focuses on four major areas of environmental politics: the formation of environmental values and attitudes, management of natural resources such as forests and fish, efforts to address international environmental issues such as climate change, and decisions relating to environmental and health risks. In each area, practical examples and case studies illustrate that science must fulfill two functions if it is to contribute to resolving environmental controversies. First, science must be relevant and credible, and second, it must be democratic, where everyone has access to the information they need to present and defend their views.
This book presents recent developments in the field of environmental biotechnology. Three major forces are currently driving this discipline: the exploration of microbial diversity by genetic and genomic tools, the ongoing progress in the modelling of various transient phenomena, and environmental biotechnology. This book provides a state-of-art-overview of developments in the field of environmental biotechnology concerning exploration, implementation, modelling, economic development and safety. It comprises selected, peer-reviewed papers that were presented at the European Symposium on Environmental Biotechnology (ESEB) 2004, held in Oostende, Belgium, April 2004.
