摘要

Due to the high level of contamination of surface water and the consequent decrease in drinking water reserves, groundwater sources are an alternative to supply the demand for water for human consumption. As a result, it is essential to monitor the potential sources of contamination that may affect the quality or quantity of water available. Thus, this study aims to identify potential polluting areas and sources of the Serra Geral Aquifer System on the hydrographic basin scale of the Turvo, Santa Rosa, Santo Cristo rivers. For this, the methodology of contamination susceptibility index was used, from crossing of a series of variables (Topography, soil use, aquifer material, distance to the water table and recharge). The results indicated that the susceptibility ranged from very low (4.89 % of the area) to high (0.004 %), with a predominance of moderate to low class. This indicates that the area presents favorable conditions for contamination in its greater portion. It is noteworthy that great part of the areas near the urban zones showed high susceptibility to contamination. This study presents the high potential of geoprocessing tools in determining the susceptibility index and mapping areas susceptible to contamination, able to improve groundwater management and the elaboration of municipal environmental plans.
