3D Resistivity Imaging on a Waste Site

P009 3D RESISTIVITY IMAGING ON A WASTE SITE 1. Introduction 1 Polluted sites are of great concern in Switzerland; The Swiss Agency for the Environment takes an inventory of more than 50’000 polluted sites. Non-invasive geophysical techniques are therefore of prime importance to specify the subsurface geometry and content of waste sites. Resistivity imaging techniques are increasingly used for subsurface characterisation due to low equipment cost rapidity of processing and ease of use. In engineering and environmental problems resistivity surveys can be applied to characterizing waste dumps or contaminant plumes (e.g. Chambers et al. 2002). These surveys are ever more
