Abstract
History of legal changes regarding a containment strategy for landfilled solid waste is summarized in this paper. The containment of landfilled solid waste consists of leaching limitations, bottom liner systems, the intermediate cover soil, final cover systems (including capping), leachate treatment systems and groundwater monitoring.
The functions of these containments are mentioned and viewpoints are discussed. We recognize anew that the aim of containment is groundwater protection so that leakage from the landfill site, when it passes through a bottom liner system that has permeability, must be controlled long after landfill closure has been completed. The flux control concept, which works from the landfill to the groundwater, is proposed here with the example of a radioactively contaminated waste landfill method whereby only the solute flux is controlled, rather than the leachate flux.
