A ubiquitous, largely overlooked groundwater contaminant, 1,4-dioxane escaped notice by almost everyone until the late 1990s. While some dismissed 1,4-dioxane because it was not regulated, others were concerned and required testing and remediation at sites they oversaw. Drawing years of 1,4-dioxane research into a convenient resource, Environmental Investigation and Remediation: 1,4-Dioxane and other Solvent Stabilizers profiles the nature of 1,4-dioxane and several dozen other solvent stabilizer compounds. The author takes an approach he calls "contaminant archeology", i.e., reviewing the history of the contaminating chemical’s use in the industrial workplace at the site of release and how those uses impart chemical characteristics to the waste that affects its fate and transport properties. The book examines the uses, environmental fate, laboratory analysis, toxicology, risk assessment, and treatment of 1,4-dioxane in extensive detail. It provides case studies that document the contaminant migration, regulation, treatment, and legal aspects of 1,4-dioxane releases. It also describes the controversy over interpretation of 1,4-dioxane’s toxicology and associated risk, as well as the corresponding disparity in states’ regulation of 1,4-dioxane. A final chapter examines the policy implications of emerging contaminants like 1,4-dioxane, with discussion of opportunities to improve the regulatory and remedial response to this persistent contaminant in the face of toxicological uncertainty. Mobility, persistence, and treatment challenges combine to make 1,4-dioxane a particularly vexing contaminant. It is more mobile than any other contaminant you are likely to find at solvent release sites. Filled with case studies, equations, tables, figures, and citations, the book supplies a wide range of information on 1,4-dioxane. It then provides passive and active remediation strategies and treatment technologies for 1,4-dioxane in groundwater and provides you with the technical resources to help you decide which are appropriate for your site.

A Practical Guide to Environmental Crime Scene Investigations Releasing contaminants into the environment—whether deliberate or unintentional—can be thought of as a crime against the environment. The role of environmental forensics is to identify and prevent environmental pollution, or crimes. Environmental Forensics Fundamentals: A Practical Guide examines this growing field, and provides environmental professionals looking to specialize in environmental forensics with the materials they need to effectively investigate and solve crimes against the environment. Pointing the Finger at Environmental Crime Environmental forensics uses "fingerprinting" techniques in order to assess and analyze contamination sites. Fingerprinting can reveal the source of contamination, as well as how, where, and when the contamination was released. This handy guidebook outlines the proven techniques, applications, and resources needed to efficiently investigate environmental crimes and become successful in this emerging field. Learn the Basics from a Single Source Divided into three main parts, the first part of the book examines the role of evidence in forensic investigations and court proceedings. It highlights general forensic concepts and offers guidelines for obtaining defensible evidence. The second part details environmental forensic investigative techniques. It includes a step-by-step guide that enables the reader to apply the techniques in practice. The final section covers strategy building. It presents real case studies, as well as key principles and concepts for strategy building, and addresses the most common challenges faced in environmental forensics. Environmental Forensics Fundamentals: A Practical Guide provides information on cutting-edge scientific techniques that investigate the source and age of environmental pollution and solve environmental crimes. It examines the principles behind each main forensic technique. It also offers guidance on what to look for in order to successfully apply the techniques and interpret results. In addition, the author provides relevant sources where more information can be found.

The term "emerging contaminants" and its multiple variants has come to refer to unregulated compounds discovered in the environment that are also found to represent a potential threat to human and ecological receptors. Such contaminants create unique and considerable challenges as the push to address them typically outpaces the understanding of their toxicity, their need for regulation, their occurrence, and techniques for treating the environmental media they affect. With these challenges in mind, this handbook serves as a primer regarding the topic of emerging contaminants, with current and practical information to help support the goal of protection where they are encountered. Features Explores the definition, identification, and life cycle of emerging contaminants. Reviews current information on sources, toxicology, regulation, and new tools for characterization and treatment of: 1,4-Dioxane (mature in its emerging contaminant life cycle) Per- and polyfluoroalkyl substances (PFASs; a newer group of emerging contaminant) Hexavalent chromium (former emerging contaminant with evolving science) 1,2,3-Trichloropropane (progressing in its emerging contaminant life cycle) Provides thoughts on opportunities in managing emerging contaminants to help balance uncertainty, compress life cycle, and optimize outcomes.

Environmental forensics is emerging and evolving into a recognized scientific discipline with numerous applications, especially regarding chlorinated solvents. This unique book provides the reader with a concise compilation of information regarding the use of environmental forensic techniques for age dating and identification of the source of a chlorinated solvent release. Concentrating on the five commonly encountered chlorinated solvents (perchloroethylene, trichloroethylene, methyl chloroform, carbon tetrachloride and CFC-113), forensic opportunities applicable to each are presented including the use of stabilizers, manufacturing impurities, surrogate chemicals and physical measurements and degradation products as diagnostic indicators. Detailed historical chronology of the applications of the solvents and specific chapters devoted to dry cleaning and vapor degreasing equipment are included as are generic forensic approaches. Forming a basis for further ideas in the evolution of environmental forensic techniques, Chlorinated Solvents will be an indispensable reference tool for researchers, regulators and analysts in the field.

Um die LebensrAume Boden, Wasser und Luft zu erhalten, Ressourcen zu schA1/4tzen und UmweltschAden energiesparend zu sanieren, werden immer neue und bessere biotechnologische Verfahren entwickelt. Vor allem werden Mikroorganismen bei der Abluftreinigung, bei der Stickstoff-, Phosphat- und Nitratelimination aus AbwAssern und Trinkwasser, beim Abbau von Fremdstoffen in BAden sowie bei der Wiederverwertung organischer Reststoffe eingesetzt. Kostenvorteile und eine weitgehende Akzeptanz durch die A-ffentlichkeit spielen dabei eine entscheidende Rolle. Ziel dieses praxisorientierten Lehrbuches ist es, Studenten und Absolventen umweltbezogener StudiengAnge die Grundmechanismen des mikrobiellen Stoffwechsels, der Energiegewinnung sowie der Abbaukinetik von Natur- und Fremdstoffen zu vermitteln. Im zweiten Teil des Buches werden verfahrenstechnische Grundlagen suspendierter Systeme und Biofilme sowie die Biotechnologie der Wasseraufbereitung, der Schlammbehandlung und des Fremdstoffabbaus in der Luft detailliert und an Hand vieler konkreter Beispiele beschrieben. WAhrend die mehr technisch ausgebildeten Studenten Vorteile aus den mikrobiologischen Kapiteln ziehen, werden biologisch/agrarwissenschaftlich vorgebildeten Studenten ihre Kenntnisse im technischen Bereich des Umweltschutzes vertiefen kAnnen. Und der Praktiker kann diesem Buch entnehmen, was Akophysiologisch realistisch und verfahrenstechnisch zu berA1/4cksichtigen ist, um sinnvolle Bemessungs- und PlanungsansAtze zu erstellen.
