Evaluation of Landfill Disposal Boundary by Means of Induced Polarization and Electrical Resistivity Imaging

Induced polarization measurements (IP) and electrical resistivity tomography (ERT) are used to define the spatial boundaries of a former municipal landfill, namely Eskelund, Denmark. The research aimed also at investigating the contamination plume in the vicinity of the waste site deposits. A clearly chargeable and conductive anomaly was evidenced, that may represent the percolation through the landfill, in agreement with drill-hole information. A further analysis should enable to check the seepage and have a 3-D tomography of the area.
