Leachate is an effluent generated by the process of decomposing bodies in cemeteries. This liquid effluent - rich in inorganic and pathogenic elements - is the main cause of pollution, with significant impacts on the soils and groundwater quality. In Brazil, the vast majority of cemeteries are located inside the urban perimeter, due to the historical lack of planning on land use and occupation. Since 2003, CONAMA - National Environment Council requires a compulsory environmental licensing for cemeteries, in accordance with the Resolution no 335 April 3, 2003. The necrochorume contains nitrogenous compounds, heavy metals and colonies of viruses and bacteria in it's composition. Its high concentration of dissolved mineral salts, in contact with the geological environment, significantly alter its physical properties. In this context, geophysics represents an important mean of investigation, especially the electrioresistivity methods, that allows extracting information on the subsurface environment and the pollutant's behavior in an indirect and noninvasive way. In this study, this method was used to detect contamination plumes in Rio Claro cemetery, where anomalous values of resistivity were associated with the presence of contamination - leachate. The present proposition aims to perform an investigation on soil contamination by using the electroresistivity method, in order to understand the physical phenomena inherent to the metodology, aquisition and interpretation of the geophysical data
