In many cases, the application of in situ technologies evolved as a necessity from a cost perspective. However, the basic understanding of the mechanisms and theory behind these technologies was treated as a "black box." Although we have seen some tremendous successes in the application of remediation technologies over the past several years, we have also seen many cases in which a technology has been incorrectly or inappropriately applied. In most cases, this misapplication has been the result of a poor understanding of the basic concepts and mechanisms behind the technologies. Without proper understanding, the potential for misapplication of technologies remains a serious economic and technical threat.

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.

The primary purpose of systems engineering is to organize information and knowledge to assist those who manage, direct, and control the planning, development, production, and operation of the systems necessary to accomplish a given mission. However, this purpose can be compromised or defeated if information production and organization becomes an end unto itself. Systems engineering was developed to help resolve the engineering problems that are encountered when attempting to develop and implement large and complex engineering projects. It depends upon integrated program planning and development, disciplined and consistent allocation and control of design and development requirements and functions, and systems analysis. The key thesis of this report is that proper application of systems analysis and systems engineering will improve the management of tank wastes at the Hanford Site significantly, thereby leading to reduced life cycle costs for remediation and more effective risk reduction. The committee recognizes that evidence for cost savings from application of systems engineering has not been demonstrated yet.

While numerous books are available on remediation systems, this is the first work to document and explain in full the design aspects of the subject. Based on sound engineering principles and practical construction considerations, this text explains the entire process of remediation design, from assessment to completion, and provides engineers with the tools they need to conduct a pilot test, apply the results, and design a practical, efficient system. Design of Remediation Systems first establishes the underlying principles behind each technology, then outlines the standard procedures for designing a system. This comprehensive manual explains feasibility and pilot tests, data evaluation, design considerations and parameters, calculations and equations, and construction aspects of the system. Also featured are discussions of the operation and maintenance of systems, and analysis of current trends, such as combining soil vapor extraction with air sparging. Detailed case study examples are included in each chapter. The book considers petroleum hydrocarbons as the primary contaminant, but the principles and procedures can be applied to a wide range of other contaminants. This hands-on text/reference presents a complete picture of remediation system design for engineers, students, and scientists. No other single work offers the thorough coverage of this critical aspect of remediation.

In situ treatments involving the arrangement of contact between prospective reactants in complex porous media require a refined understanding of solute migration. However, the tools and methods used to predict and control fluid movement in the subsurface need significant improvement. Practitioners and regulators must develop novel methods to achieve an advanced understanding of treatment mechanisms. Remediation Hydraulics addresses the need to predict and control fluid movement in the subsurface. It demonstrates how to conduct realistic assessments of contaminant plume structure and achieve contact between injected reagents and target compounds. The book describes both the advection-dispersion and continuous random walk theories of mass transport as well as explains the practical implications of each theory in remedial system design. In addition, it devotes an entire section to the development of conceptual site models and hydrostratigraphic characterization techniques that will aid practitioners in assessing the role of depositional environments in patterning groundwater flows and containment distributions. Based the authors’ sound experience at over one hundred groundwater treatment projects, this bookprovides an arsenal of relevant theories and practical applications to aid practitioners and regulators in the prediction of fluid movement in the subsurface as well as in the design of pilot to full-scale remediation systems.

The Sillamäe Metallurgy Plant in Estonia was managed by the USSR Ministry of Medium-Scale Engineering and was built in 1946 to produce uranium metal from local shales. After these were found to be unsatisfactory, uranium ores were imported. Part of the plant was converted in the 1980s to produce rare earth oxides and niobium and tantalum from imported ores and concentrates. Uranium production on the site ceased in 1990. Environmental liabilities at Sillamäe include a large pond, located on the shore of the Gulf of Finland, containing tailings from the metals processing and oil shale ash from power production. The pond's dike must be stabilised, and dust emissions, uranium and nitrate leaching must be addressed to bring the site into compliance with environmental regulations. Wastes from current processing are still being discharged to the pond, and this must cease by the end of 2002. Remediation is estimated to cost USD 22.5 million. The present volume collects information on the current situation at Sillamäe and potential solutions to its problems, based on similar experience elsewhere. A great deal of oil shale ash is present at the site and solutions to this problem may well be applicable to other sites in surrounding areas. The plant itself was closed to ethnic Estonians during the USSR's management, being populated predominantly by ethnic Russians. The technical problems are thus also addressed in broad context, meaning that the volume will also be useful to urban planners, economists and others.

Although valuable resources in river basins and other aqueous environments, sediments often receive much less attention from researchers, policymakers, and other professionals than other components of the ecosystem. Until now. Highlighting the important role that sediments play in the geoenvironment, Sediments Contamination and Sustainable Remediation focuses on sediment management for the purpose of environmental cleanup or management. It provides the in-depth understanding of the sediment-water environment needed to develop better management practices and meet sustainability requirements. The book discusses the contamination of sediments resulting from discharge of pollutants, excessive nutrients, and other hazardous substances from anthropogenic activities. It examines impacts observed as a result of these discharges, including the presence of hazardous materials and eutrophication, and elucidates the remediation techniques developed to restore the health of sediments and how to evaluate the remediation technologies using indicators. The text explores the problems inherent in dealing with contaminated sediments in rivers, lakes, and estuaries and includes numerous case studies that illustrate key concepts. The authors provide wide-ranging coverage of the topic and include methods for evaluating the effectiveness of different remediation technologies. They make the case for the development and application of innovative management practices that create long-term solutions to sediment contamination to reduce natural resource depletion, continued landfill contamination, and diminished biodiversity in the aquatic geoenvironment.

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.

In the late 1970s and early 1980s, our nation began to grapple with the legacy of past disposal practices for toxic chemicals. With the passage in 1980 of the Comprehensive Envir- mental Response, Compensation, and Liability Act (CERCLA), commonly known as Sup- fund, it became the law of the land to remediate these sites. The U. S. Department of Defense (DoD), the nation’s largest industrial organization, also recognized that it too had a legacy of contaminated sites. Historic operations at Army, Navy, Air Force, and Marine Corps facilities, ranges, manufacturing sites, shipyards, and depots had resulted in widespread contamination of soil, groundwater, and sediment. While Superfund began in 1980 to focus on remediation of heavily contaminated sites largely abandoned or neglected by the private sector, the DoD had already initiated its Installation Restoration Program in the mid-1970s. In 1984, the DoD began the Defense Environmental Restoration Program (DERP) for contaminated site assessment and remediation. Two years later, the U. S. Congress codified the DERP and directed the Secretary of Defense to carry out a concurrent program of research, development, and demonstration of innovative remediation technologies. As chronicled in the 1994 National Research Council report, “Ranking Hazardous-Waste Sites for Remedial Action,” our early estimates on the cost and suitability of existing techn- ogies for cleaning up contaminated sites were wildly optimistic. Original estimates, in 1980, projected an average Superfund cleanup cost of a mere $3.

As the result of disposal practices from the early to mid-twentieth century, approximately 250 sites in 40 states, the District of Columbia, and 3 territories are known or suspected to have buried chemical warfare materiel (CWM). Much of this CWM is likely to occur in the form of small finds that necessitate the continuation of the Army's capability to transport treatment systems to disposal locations for destruction. Of greatest concern for the future are sites in residential areas and large sites on legacy military installations. The Army mission regarding the remediation of recovered chemical warfare materiel (RCWM) is turning into a program much larger than the existing munition and hazardous substance cleanup programs. The Army asked the Nation Research Council (NRC) to examine this evolving mission in part because this change is significant and becoming even more prominent as the stockpile destruction is nearing completion. One focus in this report is the current and future status of the Non-Stockpile Chemical Material Project (NSCMP), which now plays a central role in the remediation of recovered chemical warfare materiel and which reports to the Chemical Materials Agency. Remediation of Buried Chemical Warfare Materiel also reviews current supporting technologies for cleanup of CWM sites and surveys organizations involved with remediation of suspected CWM disposal sites to determine current practices and coordination. In this report, potential deficiencies in operational areas based on the review of current supporting technologies for cleanup of CWM sites and develop options for targeted research and development efforts to mitigate potential problem areas are identified.

In the last forty years, at least fifty books have been written on the subject of soil mechanics, most of them textbooks. Only a few touch on practical applications. Soil Engineering: Testing, Design, and Remediation supplies the information needed to fill the gap between textbook learning and practical know-how. When engineers deal with major projects, such as the Teton Dam or the Leaning Tower of Pisa, they need high-tech solutions. More often than not, however, they deal with the foundations for warehouses, schools, medium-rise buildings, and residential structures, projects that need low-tech solutions. Ninety percent of the time consulting engineers don't require mathematical treatment or computer analysis, they require experience. Soil engineering problems cannot be resolved with textbook information alone. This book provides the practical meaning of the different aspects of soil mechanics, the use of unconfined compression test data, the meaning of consolidated tests, the practical value of lateral pressure, and more. In addition to the technical aspects of foundation investigation, in the real world the shadow of litigation looms over every consultant's head. The author covers legal issues in detail. After several years in foundation investigation most consultants realize that soil engineering is a combination of art and science. Soil Engineering: Testing, Design and Remediation demystifies this connection and supplies real-world examples of practical applications. This hands-on, ready reference will be essential tool for any consultant working in the field.
