http://dx.doi.org/10.5902/223611707887The last few decades have been marked by society's concern with the increasing deterioration of groundwater resources. Given this scenario, the vulnerability mapping of aquifers has emerged as an effective tool for the management of these resources, pointing to the risk of contamination of the aquifer by human activities. Accordingly outlines as main objective of this work: mapping the vulnerability of groundwater in the municipality of Santiago Rio Grande do Sul state, southern Brazil, border of Paraná Basin using the GOD method, adapted to Brazilian conditions. Therefore we prepared a database with 29 for hydrogeological catchments containing all information necessary for the method (Degree of confinement, Middle Aquifer depth and water level). The final product is a map of the vulnerability of the region under study, which identified 22 wells, totaling approximately 76.0 %, with negligible vulnerability, 17.0% showed vulnerability low, and medium and high classes presented 3.5% every one.
