Suggestion on the Leakage Pollution Control for the Historical Municipal Solid Waste Landfills in China

摘要

Artificial impermeable liner is the commonly used engineering technology method to prevent the Municipal Solid Waste (MSW) landfill leachate from polluting groundwater. The domestic and foreign researcher have discovered that the landfill impermeable liner was easy to have leaks during artificial liner laying down because of mechanical or the artificial mal-operation. The integrity test of impermeable liner for landfill began at the year of 2008. So a large number of historical landfill (construction completed before 2008) had become the pollution sources to local ecosystem because of the impermeable liner leakage. This article discussed the present situation of historical landfill leakage pollution, and propose technical and administrative measures to control those pollution in China.
