Currently there is a significant increase in the use of groundwater due to lower processing cost,distribution, and especially water shortages. Since 1960 have been drilled over 50 tubular wells tosupply about 17.000 people, which circulate in the Federal University of Santa Maria Campus, RioGrande do Sul state, southern Brazil. However, circa the 20 tubular wells were active until 2006 tomeet one average consumption of 850m3/day. This was done entirely by wells being exploitedGuarani Aquifer System/GAS, Paraná Basin. The aim was to investigate the situation andavailability of the fresh groundwaters, through preparation of a database, analysis the operationcondition of the wells to provide technical information for the grant. It was found that the watersare in accordance with guidelines for human consumption. It was also noted that there is not agood control of the piezometric levels and there was a variation of the static levels of the wells,probable assocition with the increase in the water consumption, new buildings and/or on climatechange which alter the ability of the recharge. Presents one climatic water balance for one shortperiod by five years. The aquifer system is exploited with shallow wells ranging from 47m to 128mdeep with fresh water.Key-words: aquifer, tubular
