Abstract
The characterization of Barreiras/Marituba<br>Aquifer System, major source of water supply of<br>Maceió City, Alagoas State, Brasil, is an important<br>way to subsidy a sustainable usage and management<br>of groundwater. The tectonic and stratigraphycal<br>framework that was built using well logs and surface<br>geological information propose a model with a series<br>of grabens and horsts structures. To check and<br>calibrate this geological model were applied<br>geoelectrical surveys. Based on data obtained from<br>dipole-dipole electrical profiling and vertical<br>electrical souding it was possible to identify fault<br>zones and important stratigraphycal characteristics,<br>that confirms the proposed geological model.
