Abstract

This research project aims to contribute to solving the problem of lack of water supply for local communities aiming at exploitation of aquifers (sedimentary and crystalline) in the Paraná sedimentary basin in São Paulo State. The studies will be conducted in the region of Termas de Ibirá, distant about 450km from the capital. In this region the drilled wells explore water from the aquifer sedimentary mainly related to the sandy sediment Adamantina Fm., Bauru Group. On the other hand, the fractured aquifer in the basalt layer of the Serra Geral Fm. is poorly known, the latter constitutes an excellent target for exploitation of groundwater. To map the subsurface geophysical methods will be employed: Time Domain Electromagnetic (TDEM) and Electrical Resistivity by VES. With the method TDEM the deep aquifer sediments represented by the Botucatu Formation (Guarani Aquifer) will also be characterized. Studies will be made by joint inversion 1D of TDEM/VES surveys integrated with lithological information of exploration wells groundwater. This procedure will be employed in an unprecedented way in this research and can contribute effectively to the development of research hidrogeophysics in the São Paulo State. The results will help to minimize the ambiguity inherent in the interpretation process of geophysical data, and have important implications for studies hydrogeological, for example, locating the fracture zones with water in the layer of basalt, in mapping the thickness of basalts, the orientation of the deep wells aimed at groundwater exploration in the Botucatu Formation (Guarani aquifer).
