Abstract
Electrical resistivity survey is an up-and-coming technique that involves non-destructive, prompt on-site means for conducting surveys within a landfill site. This article presents several case studies where electrical resistivity surveys were implemented at landfills by the authors. Results revealed that the electrical resistivity survey is a useful technique in that it is able to record images of (1) perched water; (2) structures such as earth-fill dams or liner sheets and; (3) the condition of progress regarding stabilization inside the landfill. In addition, progressive techniques, such as the induced polarization survey and the three-dimensional survey, are expected to be useful new approaches for investigating inside landfills.
