Emprego Do Método Da Eletrorresistividade No Estudo Da Contaminação Subsuperficial Do Cemitério De Piracicaba – Sp

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
