Due to the increasing demand for drinking water, the underground resources have been assuming a significant emphasis in the management of water resources, mainly because they are natural sources more resistant to pollution. However, in rural areas this contamination may occur due to improper soil management practices and inappropriate dumping of animal waste. One of the farming activities that can cause serious environmental damage is swine farming. Thus, this work aimed to verify if the pig farming activities in the municipality of São Gabriel do Oeste, have influenced the quality of groundwater in the region. This verification was possible by means of hydrogeological studies of the region and the accomplishment of the physical-chemical and microbiological analyzes in nine sampling points during the period of one hydrological year. Based on the hydrogeological surveys, it was verified that the waters exploited in the sampled sites are derived from the Cenozoic, Serra Geral and Guarani aquifers. Regarding the laboratory analyzes, most of the analyzed parameters did not suffer temporal variations and they remained within the limits of potability established by the legislations. In this way, it was evidenced that although swine farming is an activity with high polluting potential, it does not interfere in the quality of groundwater in the region.
