Experiment on Monitoring Leakage of Landfill Leachate Through Electrical Resistivity Tomography

Leachate leakage has become a widespread problem in most landfills due to the increasing service time. The soil property, water quality and residents’ safety around the landfill was seriously affected by the leachate leakage of landfill. A physical simulating set-up was created to simulate the leakage of leachate in the layer under the influence of flowing water. The monitoring of leachate leakage was conducted using improved electrical resistivity tomography (ERT). The result showed that the accuracy of improved ERT was more than 85% and the laboratory test relying on the simulating set-up and improved ERT was feasible. The laboratory test provides material basis for investigate the leachate diffusion quantitatively.
