To do this using the database available from CPRM for the city of Santa Rosa to Nevada with data spatializing altitude of the water table, flow of the well and STD. To make the raster data of altitude water table was used as a method of the kriging interpolation. The SRTM data represented the area on the map of the area used for potentiometric surface, which is the difference between the surface of the ground elevation of the water table. We also generated files interpolated with the data flow and STD, they were processed in ArcGIS 9.2, thereby generating the map of total dissolved solids and the flow rate by multiplying the theme STD, to obtain a map of discharge of solids. The potentiometric positive assessments have high potential of aquifer water table. They also show four high potentiometric which should primarily be secured as areas of recharge of underground springs. The use of the tools of GIS enables the provision of subsidies in making decisions regarding the planning of the use of the underground aquifer the city.
