Abstract

The current chapter analyzes different engineered measures that are put in place in landfills to safeguard the environment and the population health from release of wastes. The functions and types of covering systems are initially presented. Subsequently, the basic components of the covering systems are discussed providing details about the physical, chemical, and environmental parameters that need to be attended in different climatic and geologic conditions. The engineered barriers in the mining waste industry are further presented together with the dry, water, and organic barrier concepts that are employed for various wastes. The different types of lining systems are analyzed with emphasis on the design and construction requirements, and the properties and potential problems of clay liners, owing to the widespread use of clay as a landfill barrier. Newer types of liners, such as soil-cement and sulfur-polymer cement and concrete are detailed in terms of their capacity to absorb and retain certain chemicals from the environment, as well as their behavior under harsh conditions. Finally, the flexible membrane liners are expounded in terms of their type and performance, and the chapter concludes by presenting the control and monitoring requirements of landfills in the United States and the European Union.
