In a scenario of long periods of drought and intensive exploitation and pollution of surface water sources, the search and study of alternative sources to supplement or replace as conventional sources becomes essential for the supply of the population in the near future. Thus, the study of underground water sources is an alternative and in some cases a single option for rural populations of several cities. This work presents the results of the joint application of the electrorresistivity method for the characterization of the confined aquifer Tubarão and make fractured aquifers of the Serra Geral Formation and disseminate data in line with voids data from deep wells that have a lithostratigraphic description in the city of Cordeirópolis, . The studied aquifer is located in the Paraná Basin, especially in the Itararé Group, Tatuí Formation and Serra Geral Formation, respectively, Tuberão Aquifer and Serra Geral Aquifer. Four lines were made in Dipole-Dipole and Schlumberger arrangement by means of the electric image technique, 800 m long each and 10 m spacing between the electrodes. The results indicate areas of low resistivity near 50 m depth, related to the fractured aquifer, in addition to some zones of high resistivity from 100 m depth, which indicate the diabase of Serra Geral Formation that is not found in fractures and, consequently, no percolation of water occurs. These results corroborate a better understanding of the behavior of guarantors in the region and of how this can be exploited to serve small rural properties
