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.

Winner of the 2013 Claire P. Holdredge Awardee for Remediation of Former Manufactured Gas Plants and Other Coal-Tar Sites. This award, first established in 1962 by the Association of Environmental and Engineering Geologists, is named in honor of Claire P. Holdredge, a founding member and the first President of the Association. The award is presented for a publication by an AEG Member(s) within the 5 previous years that is adjudged to be an outstanding contribution to the Engineering Geology profession. Remediation of Former Manufactured Gas Plants and Other Coal-Tar Sites is geared toward environmental professionals who want to design and implement gasworks remediation strategies that offer the greatest chance to successfully protect the public. Exploring the bases for selecting remedial alternatives to adequately address today’s environmental wounds, this compendium of essential knowledge combines historic and modern scientific data and technology with common sense and empirical lore passed down from past generations of gas professionals, a group that is now all but extinct. Most of the general population does not have a sufficient understanding of remediation needs. Unfortunately, there seems to be a similar lack of knowledge among some environmental professionals whose job it is to protect the public from the health threats associated with coal tar. Pitfalls in remediation are common and represent a significant risk to the public, especially when processes are based on inaccurate assumptions. This book sifts through the existing scholarship from around the developed world to present the necessary evaluation factors used in effective remediation. Almost encyclopedic in scope, it offers 265 separate tables with checklists, hard data facts, and associations to help readers define site-specific gas plant conditions. It also includes a plethora of photographs and historic drawings, as well as an extensive glossary that is indispensible for understanding potential and actual gas plant contamination. Useful for engineers, scientists, regulators, public officials, historians, and journalists among others, this book is intended for those who conduct remediation, as well as those involved in review and oversight. Its goal is to bring users closer to safely reclaiming land and reviving old coal gasworks sites in ways that ultimately will be sustainable for the public interest.

Every spring, the University of Massachusetts - Amherst welcomes all ''Soils Conference" Scientific Advisory Board members with open arms as we begin the planning process responsible for bringing you quality conferences year after year. With this "homecoming" of sorts comes the promise of reaching across the table and interacting with a wide spectrum of stakeholders, each of them bringing their unique perspective in support of a successful Conference in the fall. This year marks the 20^^ anniversary of what started as a couple of thoughtful scientists interested in developing partnerships that together could fuel the environmental cleanup dialogue. Since the passage of the Superfund Law, regulators, academia and industry have come to realize that models that depend exclusively on ''command and control" mandates as the operative underpinning limit our collective ability to bring hazardous waste sites to productive re-use. It is with this concern in mind that the Massachusetts Department of Environmental Protection privatized its cleanup program in 1993, spurring the close-out of over 20,000 sites and spills across the Commonwealth to date, in a manner that is both protective of human health and the environment while also flexible and responsive to varied site uses and redevelopment goals. So we gather together again, this year, to hear our collective stories and share success and challenges just as we share stories at a family gathering. Take a read through the stories contained in these proceedings.

This volume discusses the current challenges related to the reuse of wastewater. It reviews the analytical methodologies for evaluating emerging contaminants and their transformation products, the sensitivity of various bioassays for assessing the biological effects of treated wastewater, and the bioavailability and uptake of organic contaminants during crop irrigation. It describes in detail the physicochemical and microbiological alterations in soil resulting from irrigation with treated urban wastewater, and discusses our current understanding of antibiotic resistance in wastewater treatment plants and in downstream environments. The book also includes an analysis of the effect of wastewater entering drinking water sources and production, and provides updated information on wastewater reuse for irrigation in North Africa. It presents an important integration tool for water recovery, known as water pinch analysis, and finally showcases two other examples of reuse – one in the paper industry and one in landfill management. It is of interest to experts from various fields of research, including analytical and environmental chemistry, toxicology and environmental and sanitary engineering.
