This paper shows the investigation results of contamination for necro-chorume in the freatic aquifer of Vila Rezende's cemetery, located in the north area from Piracicaba - Sao Paulo, Brazil. For that, electrical resistivity method was carried out using vertical electric sounding (VES) and 2D electrical imaging techniques using schlumberger and dipole-dipole arrays respectively. The results of VES indicate a depth of water table among 3,1 and 5,1 m with two flow directions, being a the SW and another the SE. The results of the electrical imaging (2D) indicate two probable contamination plume in unsaturated zone, a in SW and another to SE direction, both following the groundwater flow. The general results shows that these methods, used in this work, are an important indirect instrument for evaluation of the environmental quality in cemeteries. Introducao e objetivos

This paper shows the results obtained in the application of the electrical resistivity method, using the technique of the vertical electric survey (VES) and electric profiling (EP) (Schlumberger and dipole – dipole arrays), in the investigation underground contamination for - necrochorume in Vila Rezende’s cemetery, Piracicaba - Sao Paulo, Brazil. The results indicated a depth of the water table between 2 and 6m, with two directions of underground flow, SW and SE. The areas with low resistivity, presented in the geoelectrics sections, demonstrated that the contamination has connection with the depth of the water table and with the time of burial. The applied methods in this work demonstrated as an important instrument for evaluation of the environmental quality in cemeteries.
