For this reason, when they are spilled into the ground they raise the resistivity of the environment. After some time however, the action of bacterias over the organic compounds of fuels produce their biodegradation with the formation of acid that dissolve ions of the material of the ground, lowering the electric resistivity and transforming the environment into a good conductor of electricity. In summary, spilling of fuels derived from hydrocarbons produces plumes of contamination that have been associated, in geophysical surveys, as much as resistivity highs, as very low values of resistivity. In this work was intended to detect the signature in terms of resistivity of anomalies associated to contamination by fuels derived from hydrocarbons at the São Paulo Gas Station, an active gas station located in Abaetetuba-Pará and at the Braz de Aguiar Gas Station, a deactivated station, located in Belém-Pará. The geophysical measurement were carried through with the Ground Penetrating Radar Method (GPR). The study was developed along profiles covering the external perimeter of the gas stations, as well as their internal areas. The measurement were performed using a monostatic 400 MHz antenna. The data were processed with the REFLEXW software to improve the quality of the registers in order to make ease the interpretation. A signature of low resistivity was found in both gas stations.Acesso AbertoRadar de Penetração no SoloContaminação por hidrocarbonetoPluma de contaminaçãoBelém - PAAbaetetuba - PACNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICATrabalho de Curso - Graduação - Monografia
