Abstract
Geophysical methods, particularly the electrical methods, can be used to study different environmental characteristics and they are very important during the site characterization for waste disposal and monitoring of migration of contamination plumes. This paper shows the results obtained of a geoenvironmental investigation program from a municipal solid waste disposal site, that includes the use of resistivity and induced polarization methods. 2D resistivity and chargeability data obtained during geoelectrical profiling could be used to generate resistivity maps at different depths and they were used to assess the horizontal direction of contaminant flow. These results were important to determine the location of specific tests to complement the geoenvironmental site characterization as well as to define the best position for monitoring system.
