Ground penetrating radar (GPR) and geoelectrical surveys have been combined to outline underground contaminant plumes of industrial origin within a petrochemical center in Bahia, Brazil. Such plumes are invading the upper phreatic layers of a regional aquifer system which is being exploited for supplying cities and villages in the region, for industrial activities and even for the population of Salvador, the third largest city in Brazil. Three case studies are presented: two are related to conductive plumes localized beneath a metallurgical plant and an effluent treatment plant and another, a DNAPL plume below a dirt petrochemical unit. Resistivity soundings and transverse profiling were useful for a gross delineation of the aquifer structure and the extent of the contamination. GPR processed sections were employed for refining the subsurface stratigraphy and petrophysics as well as for a more precise mapping of the plume boundaries.
