Electrical resistivity by electromagnetic slingram mapping, electrical 2D and 3D imaging, and electrostatic logging: A tool for studying an old waste landfill

Many brownfields and mine sites contain acid waters which are responsible for an important mobility of the metallic ions in the environment. To plan site remediation, it is necessary to locate, estimate and describe with non-destructive methods the areas where contaminated materials are present. The aim of this study, funded by ADEME, is to define a geophysical measurement protocol which can be used on contaminated landfills in order to: i) map the distribution of contaminated materials, ii) locate the water table and its seasonal variation, iii) evaluate the water mineralization and its spatial variation, and iv) identify the water leak toward the river drain.
