The protection of groundwater and surface water from contamination by the escape of contaminant from waste disposal is now an important consideration in many countries of the world. This book deals with the design of 'barrier systems' which separate waste from the surrounding environment and which are intended to prevent contamination of both groundwater and surface waters. The authors discuss all key aspects of the design of barrier systems, including leachate collection, natural barriers such as clayey aquitards, clay liners, geomembrane and composite liners, providing a state-of-the-art work of reference of great value to engineers and environmentalists alike. This retitled second edition of Clayey Barrier Systems for Waste Disposal has been fully revised and updated, with new chapters on geomembranes and geosynthetic clay liners as well as a number of new chapters. Engineers involved with waste management, geotechnics and landfill design will use this book in order to understand the concepts, find out about the latest developments and subsequently apply them to practical applications relevant to the design of barrier systems.
President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.
Increasingly stringent regulation of pollution and waste production worldwide drives the need to isolate contaminants that pose a threat to human and environmental health by using engineered barrier systems involving the use of low permeable materials. Over the past two decades, geosynthetic clay liners have gained widespread acceptance for use in such barrier systems. They are often used as a component of primary and secondary base liners or final cover systems in municipal solid-waste landfills as well as in regulated industrial storage and mining waste-disposal facilities. This book gives a comprehensive and authoritative review of the current state of practice on geosynthetic clay liners in waste containments. It provides an insight into individual materials (bentonite and the associated geosynthetics) and the manufacturing processes. This is followed by the coverage of important topics such as hydraulic conductivity, chemical compatibility, contaminant transport, gas migration, shear strength and slope stability, and field performance.
Intrusion of plants and animals into shallow land burial sites with subsequent mobilization of toxic and radiotoxic materials has occured. Based on recent pathway modeling studies, such intrusions can contribute to the dose received by man. This paper describes past work on developing biological intrusion barrier systems for application to large volume waste site stabilization. State-of-the-art concepts employing rock and chemical barriers are discussed relative to long term serviceability and cost of application. The interaction of bio-intrusion barrier systems with other processes affecting trench cover stability are discussed to ensure that trench cover designs minimize the potential dose to man. 3 figures, 6 tables.

Principles and Practice of Waste Encapsulation is devoted to the philosophy and practice of the design and construction of encapsulation systems that control waste dispersal. The book describes both existing encapsulation systems and those in the planning stages for disposal facilities ranging from simple dumps to sophisticated mixed waste facilities. It integrates the diverse technologies and scientific disciplines that are involved in the design, construction, and maintenance of a durable encapsulation system. Technical approaches that have been developed in the last decade to provide objective quantification of the long-term (up to 1,000 years) performance of these systems are examined. Case histories are also included. Both ecological and engineering perspectives are presented in this important book for civil and geotechnical engineers, environmental scientists, environmental regulators, and others interested in permanent waste encapsulation.
Subsurface engineered barriers have been used to isolate hazardous wastes from contact, precipitation, surface water, and groundwater. The objective of this study was to determine the performance of such barriers installed throughout the United States over the past 20 years to remediate hazardous waste sites and facilities. The study focused on vertical barriers; evaluation of caps was a secondary objective. This study provides the U.S. Environmental Protection Agency's (EPA) waste programs with a national retrospective analysis of barrier field performance, and information that may be useful in developing guidance on the use and evaluation of barrier systems. The overall approach to the study was to assemble existing performance monitoring results from a number of sites, and examine those results in light of remedial performance objectives and factors that may influence performance, that is, design, construction quality assurance/construction quality control (CQA/CQC), types of monitoring programs, and operation and maintenance (O & M) efforts. A national search was launched to locate hazardous waste sites (i.e., Superfund sites, Resource Conservation and Recovery Act [RCRA] facilities, and other hazardous waste management units) at which vertical barrier walls had been used as the containment method during a remedial or corrective action. An initial list of 130 sites was developed. A subset of sites was then selected on the basis of availability of monitoring data to enable a detailed analysis of actual field performance. Where caps were present at these sites, they were included in the study as well. Two available nonhazardous waste sites and one cap-only site with extensive data were also included to further inform the study. A total of 36 sites were analyzed in detail.
