Imageamento Elétrico 2-D Aplicado À Avaliação Ambiental De Posto De Combustíveis

An study including geoelectrical<br>methods, drilling and chemical water analysis<br>was carried out in an area to determine the<br>extent of oil contamination in groundwater.<br>Resistivity method was applied using a high<br>resolution 2-D electrical imaging technique.<br>The origin of a well defined high<br>resistivity anomaly was proved to be due a<br>hydrocarbon contamination at the top of the<br>saturated zone, showing the importance of the<br>geophysical technique to this kind of problem.
