Available in PDF, EPUB and Kindle. Book excerpt: Modern landfill liners typically contain several geosynthetics and natural omponents integrated into a system whose primary function is the containment of waste and leachate. One of these hydraulic barrier components is represented by Geosynthetic Clay Liners (GCL). The GCLs are factory manufactured hydraulic barriers consisting of bentonite clay supported by geotextiles or geomembranes. Since the waterproofing function is assured by the bentonite clay it is therefore advisable to verify its chemical compatibility with the leachate and its effect upon the hydraulic conductivity value. According to the climatic situations occurring between the GCLs and waste installation, the leachate exposure moment can correspond to various GCLs hydration degrees. In this context, this paper aims at analyzing the total or partially hydrated GCL's behavior after a long time exposure to leachate. The permeability tests carried out for two needle-punched GCLs in three situations (saturated with water, water partially hydrated and saturated with leachate) show an important variation of the permeability with the hydration degree.

Available in PDF, EPUB and Kindle. Book excerpt: Soon after the inception of ASTM D35.04 Subcommittee on Geosynthetic Clay Liners, the first symposium on Testing and Acceptance Criteria for Geosynthetic Clay Liners (GCLs), STP 1308, was held on 29 January 1996, in Atlanta, Georgia. The intention of the symposium was to bring together the current knowledge and understanding regarding this relatively new product used in containment systems. Since that symposium, numerous GCL standards have been developed along with a greater appreciation of the product's capabilities and limitations. ASTM D35 determined it was time to assess the current state of GCL technology to better address possible revisions of the present ASTM GCL standards and determine what new standards will be required in the future.

Available in PDF, EPUB and Kindle. Book excerpt: In France, geosynthetic clay liners (GCLs) can be used under certain conditions within liner systems for waste containment. But there still remains a lot to learn regarding the potential modifications undergone by GCLs during prolonged contact with landfill leachate. In 2001, the French Environmental Agency (ADEME) initiated the LIXAR research program aimed at examining, at different scales of observation and for different experimental conditions, the modifications undergone by GCLs during prolonged contact with leachate. This paper focuses on the permeability-diffusion tests performed as part of this research program. Two types of needle-punched GCLs, a natural sodium bentonite GCL and a sodium-activated calcium bentonite GCL, were put in contact with three types of fluids in oedopermeameter cells. Contact duration was between 4 and 6 months. Results provide information regarding the relative performance of the two GCLs and the influence of the pre-hydration and percolation fluids.

This book was released on 2007-09-22 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth scientists and geotechnical engineers are increasingly challenged to solve environmental problems related to waste disposal facilities and cleanup of contaminated sites. The effort has given rise to a new discipline of specialists in the field of environmental geotechnology. To be effective, environmental geotechnologists must not only be armed with the traditional knowledge of fields such as geology and civil engineering, but also be knowledgeable of principles of hydrogeology, chemistry, and biological processes. In addition, the environmental geotechnologist must be completely up to date on the often complex cadre of local and national regulations, must comprehend the often complex legal issues and sometimes mind-boggling financial impli cations of a project, and must be able to communicate effectively with a host of other technical specialists, regulatory officials, attorneys, local land owners, journalists, and others. The field of environmental geo technology will no doubt continue to offer unique challenges. The purpose of this book is to summarize the current state of practice in the field of environmental geotechnology. Part One covers broadly applicable principles such as hydrogeology, geochemistry, and con taminant transport in soil and rock. Part Two describes in detail the underlying principles for design and construction of new waste disposal facilities. Part Three covers techniques for site remediation. Finally, Part Four addresses the methodologies for monitoring. The topics of 'waste disposal' and 'site remediation' are extra ordinarily broad.

Available in PDF, EPUB and Kindle. Book excerpt: Focuses on actual, state-of-the-art design/construction procedures as opposed to a discussion of solid waste management issues and to general descriptions and/or conceptual designs. Provides an integrated package of analytical tools, design equations, and step-by-step construction procedures for all elements of a landfill, giving the reader a better sense of the necessary site investigation, planning, analysis, and organization that go into a landfill design and construction project.The characteristics of landfill containment envelopes and their design/construction are treated in detail. Physico-chemical and engineering properties of solid waste that are relevant and important to landfill design and construction are tabulated and described. Includes explanation of how to evaluate and assess potential problems that affect landfill performance such as sideslope stability, settlement, containment effectiveness, and erosion control. Discusses vertical landfill expansion; how leachate moves across a liner or barrier under both advection and diffusion; compares the containment effectiveness of different liner systems to the combined advective-diffusive transport of dissolved leachate solutes. Includes a detailed explanation with numerical examples and calculations of how to design a gas collection and piping system in a landfill—including the collection and handling of condensate in the gas. Detailed installation and inspection guidelines are provided for both earthen and geosynthetic liner/cover systems—comparing the relative advantages and limitations of each.
