The city of Ipiaú developed on the banks of the rio de Contas and its tributaries. This fact, historically, causes damages to the water quality of these springs due to the lack of basic sanitation infrastructure, particularly the collection and treatment of domestic sewage. In this context, this paper aims to analyze the influence of Land Use and Occupation of Permanent Preservation Areas (APP) of rio de Contas, relating the quality of its waters and spatialize the sources of water pollution by domestic depletion. Therefore, the adopted method is based on the integrated analysis of data related to the Land Use and Occupation classes from satellite images mapping; of sanitation infrastructure from the IBGE census tracts and pre-existing water quality data from the section under study. The results attest to the scenario in which the urban census tracts that border rio de Contas present about 43% of their homes with their sewage disposal without proper treatment, in an urban area that occupies 73.9 ha within the APP in the municipality. Such a use situation implies direct and indirect consequences of water pollution.
