Abstract
Electrical sounding measurements of resistivity and induced polarization parameters combined with a selfpotencial surveywere used for mapping the sub-surface geology and hidrology around the new Salvador sanitary landfill. This landfill is located within the Rio Joanes basin, close to a surface reservoir used for water supply in the Salvador Metropolitan Area. The main aquifer<br>zone is represented by sandstones of Barreiras Formation and the wheathered basement. The geophysical results are presented as structural sections and maps showing the geometry and the lithologic variability of this aquifer. They may serve as a geophysical reference for monitoring the eventual groundwater changes caused by the landfill operation.
