Human activities, as well territorial occupation, lead to changes in environmental dynamics, affecting the natural resources especially water and soil. This situation can frequently be seen in rural settlements, where land distribution is often performed with inadequate infrastructure for occupancy. Thus, the aim of this study was to evaluate the quality of drinking water in settlements located in Teodoro Sampaio municipality, located in the state of São Paulo. The study was based on the quality of the groundwater supplied for human use, the characterization of the area including soil type, agricultural management, waste disposal, uptake and water storage conditions and the correlation of data among the settlements. The methodology used in this project was based on the non systematic observation to characterize the study area, the applied research with field work focused in experimental research with the accomplishment of physical, chemical and microbiological tests in groundwater and soil and on the application of the principal component analysis method (PCA) for correlation of results. 54 wells and 54 water reservoirs spread in 7 rural settlements were sampled, verifying that 92.5 % of the samples did not attend to the potability standards established by Ordinance No. 2914 of 2011 of the Health Ministry, mostly due to the presence of coliform bacteria. Thus, it was concluded that most of the settled families consume water out of potability standards established by the Brazilian regulations and the improvement in water quality depends on the diffusion of basic sanitation, improvement in water uptake and storage facilities and use efficient methodologies for the environmental and sanitary education of the resettled families.
