http://dx.doi.org/10.5902/223611707658 A key tool for watershed management is knowledge of sustainability indicators, describing thedynamics of environmental problems in the area of interest. It is necessary to identify indicators:Pressure that reflect the use of natural resources (soil, water and air) and the factors of production(fertilizers, pesticides and energy) state that assess the impacts on soil, water, air, biodiversity,habitats and landscapes; Answer expressing social and political efforts that are designed toimprove environmental performance. The present study aimed to demonstrate the use ofindicators of environmental sustainability combined with the analysis of natural vulnerability togroundwater contamination in the watershed. Based on the proposed objective, it can beconcluded that indicators of sustainability combined with the application of methodologies forvulnerability analysis can identify quantify environmental impacts on watersheds, especially intheir areas more susceptible to events harmful to the environment. So you can also identify themeasures taken to date assessment and enhance them and / or modify them to make them moreefficient can be directed to those areas where they really are needed, thus demonstrating theimportance of such tools in managing natural resources.
