Abstract:
It is presented a brief comparison between results obtained with two methods of vulnerability mapping to contamination of groundwater in outcrop area of the Guarani Aquifer System (SAG), in the Tietê/Jacaré Basin (State of São Paulo). The zoning of the vulnerability was stated in the scale 1: 250,000, using the methods GOD and DRASTIC. It can be concluded that the results of the two methods keep significant similarities between them, but the Method GOD suggests conservative results. For better comparison between the two methods, the mapping of vulnerability should be the exclusive search and use the same database.
