Premediation: Affect and Mediality After 9/11


Book Description

In an era of heightened securitization, print, televisual and networked media have become obsessed with the 'pre-mediation' of future events. In response to the shock of 9/11, socially networked US and global media worked to pre-mediate collective affects of anticipation and connectivity, while also perpetuating low levels of apprehension or fear.




Sediment Dredging at Superfund Megasites


Book Description

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.




Realizing Human Potential


Book Description

The proceedings of the Association for Educational and Training Technology conference on realizing human potential. These papers discuss such themes as capability, competence and enterprise and analyze the extent to which educational technology systems can be used.







Soil and Groundwater Remediation Technologies


Book Description

This book offers various soil and water treatment technologies due to increasing global soil and water pollution. In many countries, the management of contaminated land has matured, and it is developing in many others. Topics covered include chemical and ecological risk assessment of contaminated sites; phytomanagement of contaminants; arsenic removal; selection and technology diffusion; technologies and socio-environmental management; post-remediation long-term management; soil and groundwater laws and regulations; and trace element regulation limits in soil. Future prospects of soil and groundwater remediation are critically discussed in this book. Hence, readers will learn to understand the future prospects of soil and groundwater contaminants and remediation measures. Key Features: Discusses conventional and novel aspects of soil and groundwater remediation technologies Includes new monitoring/sensing technologies for soil and groundwater pollution Features a case study of remediation of contaminated sites in the old, industrial, Ruhr area in Germany Highlights soil washing, soil flushing, and stabilization/solidification Presents information on emerging contaminants that exhibit new challenges This book is designed for undergraduate and graduate courses and can be used as a handbook for researchers, policy makers, and local governmental institutes. Soil and Groundwater Remediation Technologies: A Practical Guide is written by a team of leading global experts in the field.




Site Remediation


Book Description

Site Remediation: Planning and Management describes the management of remediation from a planning perspective, skillfully combining Superfund requirements and site remediation strategy in one practical volume. It clarifies and suggests remedies for the current quagmire of confusing Superfund reform and slow, expensive site remediation by thoroughly explaining the Superfund program and then describing how each of its components can fit into an integrated planning and management strategy. Site Remediation covers environmental sampling, site characterization, risk assessment, cleanup criteria, technology and technology screening, and public participation. Detailed and comprehensive, yet easy to understand, this book contains all you need to know about this important subject.







Contaminants in the Subsurface


Book Description

At hundreds of thousands of commercial, industrial, and military sites across the country, subsurface materials including groundwater are contaminated with chemical waste. The last decade has seen growing interest in using aggressive source remediation technologies to remove contaminants from the subsurface, but there is limited understanding of (1) the effectiveness of these technologies and (2) the overall effect of mass removal on groundwater quality. This report reviews the suite of technologies available for source remediation and their ability to reach a variety of cleanup goals, from meeting regulatory standards for groundwater to reducing costs. The report proposes elements of a protocol for accomplishing source remediation that should enable project managers to decide whether and how to pursue source remediation at their sites.







The Economics of Groundwater Remediation and Protection


Book Description

Economic literature is often too theoretical for engineers and policymakers to put into practical use, while scientific literature on the remediation of contaminated aquifers rarely considers costs and benefits. Written by a hydrogeologist and an economist, The Economics of Groundwater Remediation and Protection integrates economics and cost-benefit analysis tools with optimal protection and remediation strategies for groundwater resources. The book provides a thorough introduction of the concepts of groundwater flow and contaminant transport, and the basics of economic decision making techniques. It illustrates the types of risks and impacts caused by groundwater contamination, and the economic benefits of its remediation. The volume reviews a wide range of issues such as cost, implementation, and expectations of success for the latest remediation trends and techniques. The book shows how economic analysis can be used to determine how much we should pay for groundwater clean-up, and when spending too much - or too little - actually makes us all worse-off. The authors' step-by-step methodology for decision-making focuses on determining optimal remedial objectives, from containment to extensive cleanup, and the selection of least-cost alternatives. They use examples from their personal experience to illustrate the methodologies in action and put the issues into perspective. Combining the theoretical and practical aspects of science, policy, and economics, this book places the importance of groundwater remediation in the context of environmental economics, protection, and preservation. The Economics of Groundwater Remediation and Protection is also an excellent introduction to innovative solutions for funding remediation projects, education, and incentive programs, such as mitigation banking, land pollution credit schemes, and conservation credit alternatives.
