Book Description
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 Description
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 Description
Natural attenuation was first demonstrated at sites with hydrocarbon contamination, but recent studies at sites contaminated by chlorinated compounds have shown that this approach often has merit for these more challenging contamination problems. This volume covers natural attenuation in media ranging from deep aquifers to shallow soils, and for contaminants ranging from fuels to solvents to herbicides, and offers the reader a comprehensive overview of case studies that represent the state of the art in natural attenuation approaches to site remediation.

Book Description
Sponsored by the Natural Attenuation Task Committee of the Environmental and Multi-Media Council of the Environmental and Water Resources Institute of ASCE. This report provides the regulatory framework, scientific and engineering principles, and applications of natural attenuation for the remediation of contaminated sites. Natural attenuation is a process that relies on the natural assimilative capacity of a site to reduce or stabilize contaminates to desirable levels. It is becoming an increasingly popular, cost-effective remedial alternative for many contaminated sites. The report describes in detail sites contaminated with petroleum hydrocarbons and MTBE, chlorinated solvents, polycyclic aromatic hydrocarbons, metals, and radioactive wastes. Topics include: Ømajor pollutants; Øextensive review of literature; Øexamples of applications of natural attenuation; Øsite characterization and monitoring requirements and procedures; and Øbasic scientific principles on physical, chemical, and biological processes. Environmental engineers and scientists will find this book full of information on basic principles to summaries of natural attenuation applications.

Book Description
Halogenated organic compounds constitute one of the largest groups of environmental chemicals. The industrial production of new halogenated organic compounds has increased throughout the last century peaking in the 1960s, and continuing in widespread use today. Organohalides are integral to a variety of industrial applications, including use as solvents, degreasing agents, biocides, pharmaceuticals, plasticizers, hydraulic and heat transfer fluids, and intermediates for chemical synthesis, to name a few. It is important to recognize the beneficial aspects of halogenated organic compounds, as well as their potentially deleterious impact on the environment and health. Recognition ofthe adverse environmental effects ofmanytypes oforganohalide compounds has led to efforts to reduce or eliminate the most problematic ones. Although organohalide compounds are typically considered to be anthropogenic industrial compounds, they have their counterpart in several thousands of natural biogenic and geogenic organohalides, representing most classes of organic chemicals. Natural sources account for a significant portion of the global organohalogen budget. This volume authored by recognized experts in the field provides a current perspective on how both natural and synthetic organohalides are formed and degraded, and how these processes are incorporated into a global halogen cycle. The focus is on microbial processes, since these play a major role both in the production and degradation, i. e. , cycling of halogenated organic compounds inthe environment. This book is organized into five parts. Part I, Introduction, provides a global perspective on the issues of organohalides and their fate in the environment.
