Book excerpt: Rocky Mountain Arsenal (RMA) was for many years a site of military chemical weapons manufacturing activities, including manufacture and assembly of weapons containing intermediate and toxic chemical end-products, incendiary munitions, blending of hydrazine compounds for rocket fuels, and, under civilian jurisdiction, the manufacture of pesticide and herbicide chemicals. As a result of these activities, many contaminants have migrated into the soil and moved into portions of the shallow alluvial aquifer. Chemical analyses by both RMA and Shell Chemical have detected N-nitrosodimethylamine (NDMA), also known as dimethylnitrosamine, within the groundwater around the North Boundary Containment System (NBCS), RMA, and in the NBCS influent and effluent. This compound is of concern because of its mutagenic, carcinogenic, teratogenic, and hepatotoxic properties. While NDMA has been found in water samples collected from observation wells located on RMA, this compound has not been detected in any of the off-post wells. Previously collected data suggested that the granular activated carbon in the groundwater treatment system is not very effective in the removal of NDMA from the system influent. To examine the possibility that NDMA might migrate off-post from RMA and contaminate nearby drinking water supplies and to evaluate the potential that natural sorptive and microbial degradative processes might successfully remove NDMA as a threat, a study was undertaken to examine the sorption capacity of saturated alluvial aquifer soils at the NBCS for NDMA and assess the potential for microbially mediated losses of NDMA to destroy this compound throughout the NBCS. Results indicated that sorptive processes were likely to remove little, if any, NDMA from the groundwater. By contrast. microbial degradative processes were observed to actively destroy NDMA.

Book Synopsis Permeable Barriers for Groundwater Remediation by : Arun R. Gavaskar
Download or read book Permeable Barriers for Groundwater Remediation written by Arun R. Gavaskar and published by . This book was released on 1998 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the limitations of conventional pump-and-treat systems in treating groundwater contaminants, permeable barriers are potentially more cost-effective than pump-and-treat systems for treating dissolved chlorinated solvent plumes, which may persist in the saturated zone for several decades. Other contaminants, such as chromium or other soluble heavy metals, can also be treated with this technology. Permeable Barriers for Groundwater Remediation discusses the types of permeable barriers, their design and construction, and how they can be monitored to evaluate compliance. It provides practical guidance on reactive media selection, treatability testing, hydrogeologic and geochemical modeling, and innovative installation techniques for the evaluation and application of this promising new technology. The types of permeable barriers discussed include: trench-type and caisson-based reactive cells; innovative emplacements, such as horizontal trenching and jetting; and continuous reactive barriers versus funnel-and-gate systems.
Book Synopsis Natural Attenuation by : Patrick V. Brady
Download or read book Natural Attenuation written by Patrick V. Brady and published by CRC Press. This book was released on 1997-09-24 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural Attenuation: CERCLA, RBCAs, and the Future of Environmental Remediation presents the concept of "natural attenuation"-the tendency of soils to severly limit the toxicity of many types of hazardous waste. It reviews and updates the most recent findings from the field and lab and shows how natural attenuation is rapidly changing the direction and focus of environmental remediation. Outlining the legal and regulatory framework that has made waste remediation so costly, this book shows how applying an understanding of natural attenuation can decrease cleanup outlays while lowering risks to human health. Natural Attenuation: CERCLA, RBCAs, and the Future of Environmental Remediation makes it clear why natural attenuation will be relied upon more and more in the future.

Book Synopsis Algal Biorefineries by : Aleš Prokop
Download or read book Algal Biorefineries written by Aleš Prokop and published by Springer. This book was released on 2015-10-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae offer potential to produce renewable chemicals and fuels using solar energy and carbon dioxide from atmosphere or in flue gases while simultaneously reducing the generation of greenhouse gases. Since these can be grown on marginal lands with micronutrients and macronutrients often present in waste streams, algae-based chemicals and fuels do not compete with foods. Still large-scale production of algae-based fuels and chemicals faces considerable technological and economical challenges and it would by necessity require a biorefinery approach wherein all the possible algal components are converted into value-added compounds. The present series on algal biorefineries represents a forum for reporting the state of the art of different technologies as well as the latest advances in this field. The volume II of this series complements the volume I in terms of the current state of the art. Different chapters in this volume address diverse issues ranging from genetically modifies algae to new products to life-cycle analysis of algal products.
Book Synopsis Learning Progressions in Science by : Alicia C. Alonzo

Available in PDF, EPUB and Kindle. Book excerpt: Learning progressions – descriptions of increasingly sophisticated ways of thinking about or understanding a topic (National Research Council, 2007) – represent a promising framework for developing organized curricula and meaningful assessments in science. In addition, well-grounded learning progressions may allow for coherence between cognitive models of how understanding develops in a given domain, classroom instruction, professional development, and classroom and large-scale assessments. Because of the promise that learning progressions hold for bringing organization and structure to often disconnected views of how to teach and assess science, they are rapidly gaining popularity in the science education community. However, there are signi?cant challenges faced by all engaged in this work. In June 2009, science education researchers and practitioners, as well as scientists, psychometricians, and assessment specialists convened to discuss these challenges as part of the Learning Progressions in Science (LeaPS) conference. The LeaPS conference provided a structured forum for considering design decisions entailed in four aspects of work on learning progressions: de?ning learning progressions; developing assessments to elicit student responses relative to learning progressions; modeling and interpreting student performance with respect to a learning progressions; and using learning progressions to in?uence standards, curricula, and teacher education. This book presents speci?c examples of learning progression work and syntheses of ideas from these examples and discussions at the LeaPS conference.

This book was released on 2000-08-31 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, officials responsible for clean-up of contaminated groundwater have increasingly turned to natural attenuation-essentially allowing naturally occurring processes to reduce the toxic potential of contaminants-versus engineered solutions. This saves both money and headaches. To the people in surrounding communities, though, it can appear that clean-up officials are simply walking away from contaminated sites. When is natural attenuation the appropriate approach to a clean-up? This book presents the consensus of a diverse committee, informed by the views of researchers, regulators, and community activists. The committee reviews the likely effectiveness of natural attenuation with different classes of contaminants-and describes how to evaluate the "footprints" of natural attenuation at a site to determine whether natural processes will provide adequate clean-up. Included are recommendations for regulatory change. The committee emphasizes the importance of the public's belief and attitudes toward remediation and provides guidance on involving community stakeholders throughout the clean-up process. The book explores how contamination occurs, explaining concepts and terms, and includes case studies from the Hanford nuclear site, military bases, as well as other sites. It provides historical background and important data on clean-up processes and goes on to offer critical reviews of 14 published protocols for evaluating natural attenuation.

Book Synopsis The Role of Ecological Chemistry in Pollution Research and Sustainable Development by : Ali Mufit Bahadir
Download or read book The Role of Ecological Chemistry in Pollution Research and Sustainable Development written by Ali Mufit Bahadir and published by Springer. This book was released on 2009-08-03 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Development has become the leading concept of the 21 century. It describes a development, which agrees with the needs of the present generation but does not endanger the chances of the coming generations to satisfy also their needs. “Sustainable development” has become an important general goal for all fields of life like economy, ecology and social balance. The development and shaping of our future has been discussed internationally like on the summits of the Conferences in Rio and in Johannesburg. But this is also a topic on national base in various countries. Leading authorities in various fields of economy and politics have also accepted this concept. Although the concept of sustainable development has been generally accepted, there are still problems how to achieve and evaluate these general goals. It is clear that the definitions about the prime needs vary from man to man, from country to country and from continent to continent. But pollution does not respect national borders. Therefore, it is necessary to develop the politics of economy, ecology and social demands by a synergistic way that they are strengthened by each other. If it is not possible to stop tendencies, which threaten the future quality of life, the cost demands of societies will dramatically increase and negative tendencies will become irreversible.
