Resumo:
Resistivity sounding surveys are currently employed by members of the Programa de Pesquisa e Posgraduação em Geofísica at the Federal University of Bahia, Brazil, in the study of groundwater problems. The tripotential technique with the Wenner configuration is preferred to other more traditional methods. Higher quality and more useful results are obtained. An example from the city of Canavieiras, Bahia, Brazil, is detailed.
