Detecting groundwater in fractured aquifers is always a difficult task. This paper presents the detailed study of a fractured aquifer in Lindóia region, São Paulo, Brazil. The study area was selected after a regional study analyzing the favorability for occurrence of groundwater which classified the area as being of excellent groundwater favorability. The study consisted on fractures mapping based on aerial photographs (scale 1:25,000) and geoelectrical survey (vertical electrical sounding and resistivity imaging). The geophysical data was processed, inverted and analyzed by using geological field data, wells data, springs data and fractures mapped using aerial photographs. The results show that it was possible to define favorable locations for the wells and optimize field work.
