Abstract
Summary
The use of 2D and 3D electrical resistivity tomography (ERT) techniques, in combination with the use of geochemical analyses and geomechanical drilling, has enabled us to develop a methodology for diagnosis and precise quantification of an area potentially affected by slurry in the subsoil. That methodology attempted to characterize the different soil types in the regions studied, about their natural impermeability to subsurface slurry infiltration. Its findings contributed to obtaining precise information on the impact of pig slurry pond activity on the subsoil and a more global idea of how the contaminant plume spreads in terms of horizontal and vertical extension into the subsurface.
