Alternative Landfill Cover. Subsurface Contaminants Focus Area andCharacterization, Monitoring, and Sensor Technology Crosscutting Program. Innovative Technology Summary Report

摘要

The U.S. Department of Energy (DOE) has many sanitary, hazardous, radioactive,and mixed-waste landfills, as well as mine-spoil and mill-tailings piles, and surface impoundments, which must be closed. Reducing contaminant concentrations to acceptable levels entails some type of remediation, such as: in-place stabilization, capping with an engineered cover; or, a combination of these activities as part of the closure activity. Also, engineered covers may be considered as an interim measure to be placed over a contaminated area until a more permanent solution can be implemented.
