Sanitary landfill is the most common way to eliminate solid urban wastes. An important problem associated to this practice is the leachate production and the related groundwater contamination. The leachate electrical conductivity is often so much higher than natural groundwater, consequently a large contrast in this property is seen which enables the plume to be detected using geophysical methods.  Furthermore, the hydrochemical parameters computed in the most conductivity zone were also useful to evaluate the present environmental conditions and from electric conductivity values of the most conductive sections it?s possible to predict leachate geochemical parameters applying empiric relations. In particular the groundwater electrical conductivity was estimated and in general, it has analogous values to the conductivity determined from superficial waters and lower values than those measured in phreatic wells.
