Book excerpt: Remediation of groundwater is complex and often challenging. But the cost of pump and treat technology, coupled with the dismal results achieved, has paved the way for newer, better technologies to be developed. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a buried porous barrier that either captures the contaminants or breaks them down. And although this approach is gaining popularity, there are few references available on the subject. Until now. Permeable Reactive Barrier: Sustainable Groundwater Remediation brings together the information required to plan, design/model, and apply a successful, cost-effective, and sustainable PRB technology. With contributions from pioneers in this area, the book covers state-of-the-art information on PRB technology. It details design criteria, predictive modeling, and application to contaminants beyond petroleum hydrocarbons, including inorganics and radionuclides. The text also examines implementation stages such as the initial feasibility assessment, laboratory treatability studies (including column studies), estimation of PRB design parameters, and development of a long-term monitoring network for the performance evaluation of the barrier. It also outlines the predictive tools required for life cycle analysis and cost/performance assessment. A review of current PRB technology and its applications, this book includes case studies that exemplify the concepts discussed. It helps you determine when to recommend PRB, what information is needed from the site investigation to design it, and what regulatory validation is required.

Download or read book Evaluation of Permeable Reactive Barrier Performance written by and published by . This book was released on 2002 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permeable reactive barriers (PRB) are developing into an entire new class of technologies for groundwater remediation. A permeable barrier is a porous "barrier" that is placed in the path of a groundwater plume, in various configurations. The barrier, or at least the permeable portion of the barrier, contains a reactive or adsorptive medium that helps remove the contaminants from the plume, as the groundwater flows through the barrier. The primary advantage of permeable barriers is their passive operation and the resulting potential for long-term cost savings. The technology emerged in the mid-1990s with the use of granular zero-valent iron as a reactive medium for treatment of groundwater contaminated with chlorinated volatile organic compounds (CVOCs), such as trichloroethylene (TCE) and perchloroethylene (PCE). More recently, there is interest in developing other treatment media and methods of construction to address a broader variety of contaminants and sites.

Book excerpt: The focus of the presentstudy was centered on the modeling analysis to support the Permeable Reactive Barrier (PRB) design. The flow model formulated to simulate the Permeable Reactive Barrier System integrated the available geologic, hydro geologic and geo-chemical data from numerous recent installations to simulate a subsurface ground water scenario. Different generic cases that a PRB system would fall into were identified based on its utility and aquifer conditions and then employed to produce different model adaptations. The different simulation codes and interfaces were evaluated, and the most expedient of them was used to simulate the Model. The simulations were then used to study the sensitivity of different parameters and identify those that were critical to the design of the system. Design curves, devised to aid the design of a barrier, were verified with the residence time curves mapped for the same parameters. The results of the sensitivity analysis and the developed design curves were used to arrive at a uniform procedure for the design of a Continuous Configuration Barrier System. The procedure was appraised by working through the design of a Permeable Reactive Barrier at a GW contaminated site located in the Piedmont Province of the Appalachian Highlands in New Jersey.

Available in PDF, EPUB and Kindle. Book excerpt: The implications of biodiversity loss for the global environment have been widely discussed, but only recently has attention been paid to its direct and serious effects on human health. Biodiversity loss affects the spread of human diseases, causes a loss of medical models, diminishes the supplies of raw materials for drug discovery and biotechnology, and threatens food production and water quality. Biodiversity and Human Health brings together leading thinkers on the global environment and biomedicine to explore the human health consequences of the loss of biological diversity. Based on a two-day conference sponsored by the National Institutes of Health, the National Science Foundation, and the Smithsonian Institution, the book opens a dialogue among experts from the fields of public health, biology, epidemiology, botany, ecology, demography, and pharmacology on this vital but often neglected concern. Contributors discuss the uses and significance of biodiversity to the practice of medicine today, and develop strategies for conservation of these critical resources. Topics examined include: the causes and consequences of biodiversity loss emerging infectious diseases and the loss of biodiversity the significance and use of both prescription and herbal biodiversity-derived remedies indigenous and local peoples and their health care systems sustainable use of biodiversity for medicine an agenda for the future In addition to the editors, contributors include Anthony Artuso, Byron Bailey, Jensa Bell, Bhaswati Bhattacharya, Michael Boyd, Mary S.

Book excerpt: Like articles representing the positions of proponents of the measure, those representing opponents construct the nation as potentially in danger as a result of undocumented immigration. How do we learn to recognize the damning effects of good rhetorical intentions? And where will we find arguments which escape this trap that permeates the liberal social policy world? Shifting Borders uses an evaluation of the debate over California Proposition 187 to demonstrate how this quandary is best understood by close interrogation of mainstream reports and debates and by bringing to the fore voices that are often left out of mediated discussions. It is these voices outside the mainstream, so called outlaw discourses, that hold the best possibilities for real social change. To illustrate their claim, the authors present dominant and outlaw discourses around Proposition 187, from television reports, internet chat sites, and religious discourse to coverage of the Los Angeles Times. Their critique ably demonstrates how difficult it is to maintain a position outside the mainstream, but also how important it is for the press, citizens, and scholars to actively search out such voices. The find

Download or read book Culture and Imperialism written by Edward W. Said and published by Vintage. This book was released on 2012-10-24 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: A landmark work from the author of Orientalism that explores the long-overlooked connections between the Western imperial endeavor and the culture that both reflected and reinforced it. In the nineteenth and early twentieth centuries, as the Western powers built empires that stretched from Australia to the West Indies, Western artists created masterpieces ranging from Mansfield Park to Heart of Darkness and Aida. Yet most cultural critics continue to see these phenomena as separate. Edward Said looks at these works alongside those of such writers as W. B. Yeats, Chinua Achebe, and Salman Rushdie to show how subject peoples produced their own vigorous cultures of opposition and resistance. Vast in scope and stunning in its erudition, Culture and Imperialism reopens the dialogue between literature and the life of its time.
Download or read book Water Reuse written by National Research Council and published by National Academies Press. This book was released on 2012-07-17 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.
