1 of 4
The most comprehensive design reference available on remediation techniques, waste disposal methods and various waste containment systems. Covers several important new issues such as the regulatory structure of RCRA Subtitles C and D; subsurface flow and transport of contaminants; liner systems, leachate collection and removal systems for landfills; and seismic stability analysis of landfills. Describes new waste stabilization technologies including the process of converting non–solid toxic waste into inert solids.
