This work is the application of geophysical methods, using the Ground Penetrating Radar (GPR), with the objective of survey in a subsurface plume of contamination caused by a disabled gas station. The gas station is located on the Búzios beach in southern coast of the state to Rio Grande do Norte in an Area of Environmental Protection called Bonfim-Guaraíra. The interest to develop this work was the presence of contaminants (hydrocarbons) in a well located on the desktop, previously used for the abstraction of groundwater for residents living near the site. Were raised 15 geophysical survey lines totaling 775,48 lifting and installed 4 piezometer, to confirm the contamination and prepare a pluviometric map that helped in indicating the direction of local groundwater flow, thus showing the direction of movement of the probably plume of contamination. From the processing of the GPR lines was possible to identify two likely phases of contamination according to the classification proposed by Azambuja et al 2000, which are called phase absorbed and dissolved phase
