Özet
The design of lining systems for the containment of liquids, for example to contain the leachate generated within a landfill, has become rather sophisticated, employing the state-of-the-art technologies from such disparate disciplines as geotechnical engineering and polymer science. The objective, and to a confident degree, the achievement, has been the prevention of contamination of groundwater and in particular surface waters that support humans and animals alike. The technology involving the design of these systems has progressed to a point that the integrity of the containment can be relied on over the long term. With double lined systems, the additional benefit of being able to quantify the performance of the lining system through the detection of leakage through the upper liner. The difficulty, however, lies with the qualitative evaluation of the system - how much leakage is a little? a lot? too much? This paper addresses this issue and offers a practical approach for the design and evaluation of double lined systems and the leakage that is detected.
