The preservation of the environment in general depends of programs that promote the development of more sustainable societies. The aim of this work was to study social and environmental aspects, as well as the level of water contamination and soil by heavy metals in the Ajuricaba basin stream water, located in the city of Marechal Cândido Rondon, Paraná state, Brazil. First, was applied a form to residents of the watershed to verify the adopted cropping systems and ways of management. Through this form, can evaluate the routine of agricultural activities, especially those that may result in soil contamination sources and water resources. After the survey, were selected 15 properties of 38 that were visited to perform subsequent collection of soil and water. In the second stage were collected spring water, creeks, wells, weir and river, as well as ground which were analysed to detect heavy metals such as Cadmium (Cd), Chromium (Cr) and Lead (Cd). The data collected, through the form, showed that the site is characterized by small farms, 78% of them are smaller than 25 hectares, using basically family labor, merged by soybean and corn, the cattle, swine, poultry and some fish farmers. The analysis of water resources for heavy metals Cadmium (Cd), Chromium (Cr), lead (Pb) showed satisfactory results, so there’s no contamination by metal traces. However, in soil samples detected the presence of lead in all samples analyzed between 41 mg/kg and 53 mg/kg.
