Landfill leakage detection method based on resistivity anomaly

At present, almost all the impermeable layers of landfills have leakage problems. Accurate detection of leakage points and monitoring of pollution plumes are of great significance to landfill pollution treatment and restoration. In this study, in-situ resistivity detection was used at the bottom of the landfill site, and Visual MODFLOW was used to establish a solute transport model of the landfill site. The results show that the specific location of the leakage point can be well detected by comparing resistivity anomalies before and after the leakage, and the groundwater model can be verified by converting resistivity data into concentration data. It verifies the feasibility of in-situ resistivity detection and realizes the prediction of pollution plume migration path, which can provide certain technical support for landfill leakage treatment and repair.
