Resistivity imaging and Ground Penetrating Radar survey at Gualeguaychú landfill, Entre Ríos Province, Argentina: Evidences of a contamination plume

Some multi-electrode resistivity studies were performed within and outside the landfill as part of the environmental project. The apparent-resistivity data were collected using a dipole-dipole survey with 21 electrodes (spaced a=5m with n= 1, ...,18), to give a total line-length of 100 meters. Data inversion was carried out using the DCINV2D program. All the subsequent inversions had a RMS less than 2. The depth of investigation (DOI) was estimated around 25 meters.
