This book was released on 2002-10-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last century and a half, groundwaters have become contaminated by a growing number of organic and inorganic substances ranging from petroleum-derived hydrocarbons to radioactive compounds, to cancer-causing hexavalent chromium. The importance of uncontaminated groundwater for agriculture, human consumption, and the environmental health of ecosystems is paramount to the health and productivity of industrial society. Water scientists and managers are focused on developing cost-effective methods to reverse this trend.Several methodologies have been developed, however few are as cost-effective as the use of readily available materials, such as iron and organic compost, for absorbing and isolating contaminants within the matrix of a permeable barrier. The Handbook of Groundwater Remediation using Permeable Reactive Barriers presents readers with this latest technology and developments within four main sections:1. Innovations in Design, Construction, and Evaluation of PRBs2. Development of Reactive Materials3. Evaluations of Chemical and Biological Processes4. Case Studies of Permeable Reactive Barrier InstallationsThe Handbook is one of the first references specifically on this topic. It is an excellent fit for graduate students entering this emerging field as well as professionals conducting research or implementing this technology.

Download or read book Permeable Reactive Barrier written by Ravi Naidu and published by CRC Press. This book was released on 2018-10-08 with total page 333 pages. Available in PDF, EPUB and Kindle. 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 Environmental Mineralogy II written by D.J. Vaughan and published by The Mineralogical Society of Great Britain and Ireland. This book was released on 2013-02-06 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a sense, all mineralogy is environmental mineralogy. However, the term environmental has come to be employed (particularly in combination with terms such as science, issue or problem) to refer to those systems at or near the surface of the Earth where the geosphere comes into contact with the hydrosphere, atmosphere and biosphere. This is, of course, the environment upon which the human race depends for survival and, hence, is now sometimes referred to as the critical zone. Those systems containing minerals that constitute the most important or key environments are considered here: soils, modern sediments, atmospheric aerosols, and the interior or exterior parts of certain micro- and macro-organisms. Particularly important are the roles that minerals play in processes that act over time to control or influence the environment at various scales of observation. Both pure systems and those contaminated as a result of human activity are considered. The objectives for this volume are to help to define the subject of environmental mineralogy, and to provide an initial source of information both for mineralogists and other scientists who wish to understand or work in this field. It was hoped that it might also provide a text for use by those teaching courses in the subject at advanced undergraduate or graduate student level.

Download or read book Mine Water written by Paul L. Younger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowhere is the conflict between economic progress and environmental quality more apparent than in the mineral extraction industries. The latter half of the 20th century saw major advances in the reclamation technologies. However, mine water pollution problems have not been addressed. In many cases, polluted mine water long outlives the life of the mining operation. As the true cost of long-term water treatment responsibilities has become apparent, interest has grown in the technologies that would decrease the production of contaminated water and make its treatment less costly. This is the first book to address the mine water issue head-on. The authors explain the complexities of mine water pollution by reviewing the hydrogeological context of its formation, and provide an up-to-date presentation of prevention and treatment technologies. The book will be a valuable reference for all professionals who encounter polluted mine water on a regular or occasional basis.

This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aqueous geochemical computer modeling was carried out for an aquifer contaminated with acid mine drainage at the South Bay mine site to test the feasibility of a proposed bioremediation treatment plan. The treatment consists of adding urea to the aquifer to stimulate growth of indigenous urea-degrading bacteria that produce carbonate and ammonium. These products have the potential for neutralizing the groundwater and precipitating iron oxides, which may remove heavy metals from solution through sorption processes. With aqueous geochemical data for piezometers situated along a hydraulic gradient from the tailings area to the aquifer's discharge zone, a model of the aquifer's geochemistry was constructed with the program MINEQL +. Once the model was calibrated to ensure that calculated pH values matched measured field pH values, titrations with the urea-degradation products were undertaken to simulate introduction of the urea-degradation products into the groundwater over time. The amount of carbonate and ammonium required to raise the pH in the piezometers to 8.0-8.1 ranged from 3.5 * 10 -5 M - 0.24 M and 7.0 * 10-5 M - 0.48 M, respectively. As is evident with observed pH increases and oxide supersaturation as a result of the titrations, the metabolic products of microbial urea degradation have been proven to have considerable potential for treating contaminated groundwater at South Bay.
