Full Description
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.
