Abstract

The objective of this work is to elaborate a thematic map of the intrinsic vulnerability of the aquifer in the Metropolitan Region of Salvador (RMS), which constitutes the first step for the assessment of the danger to contamination and protection of the groundwater quality. For this, the GOD methodology was used. In the RMS, four vulnerability patterns were found: negligible, low; moderate and high. The GOD method clearly showed the natural vulnerability to contamination, however, it involves simplifications in hydrogeological information, which requires attention when reclassifying, processing the data and interpreting the results.
