A PRELIMINARY UNDERSTANDING ON PERFORMANCE OF BARRIERS FOR MSW LANDFILLS IN SOUTHERN CHINA
A barrier system, consisting of bottom barrier, lateral barrier and top cover, is the most important component of a controlled MSW landfill. Numerous research efforts have been put to study the performance of the basal liners for MSW landfills. However, relatively few studies were carried out on the resistance of basal liners to a high leachate mound, which is commonly present at landfills in Southern China. In addition, the investigation on the performance of vertical barriers is relatively scarce. This paper tried to present some preliminary understanding on the performance of landfill barriers in the south of China. The paper firstly presents a field investigation on the transport of leachate pollutant at the Suzhou MSW landfills with vertical barrier installed. Then, the performance of four regulatory liner systems subjected to a high leachate mound will be discussed, and some implications on the barrier design are given. The paper also includes a review on the recent advances on alternative earthen covers for MSW landfills.
