The study aimed to develop environmental assessment in the watershed of the Bandeirantes stream, at the county of Rio Claro, in the state of São Paulo, Brazil, noting the problems caused by urban occupation. The data were collected by field observations, study of the watershed hydrological and geotechnical map analysis, allowing assess current conditions of the area. From the results we can draw up a list of environmental impacts caused by chaotic urbanization. The study confirmed the change of water infiltrating the ground for the occupation, causing a series of erosion processes, including forming a large erosion (boçoroca). Accordingly, the diagnosis identified the main problems of the area and propose measures to mitigate and control existing and potential impacts.Keywords: water resources, waste, soil and water pollution.
