摘要：This work had the objective to implant the sanitation program of groundwater in all rural schools in the District of Ibiúna-SP. In order to execute it, samples were collected in 50 schools before and after the interventions, for microbiological and physical-chemistry analyses. It was identified the main contamination risk factors. It was installed alternative systems of chlorine and fluoridation and developed educative actions with the involved persons in this work. The microbiological result, after interventions, showed that the program was satisfactory, with the absence of coli forms in all samples after interventions. The association and the inclusion of fluorine permitted adequate concentrations of that element in the water. About risk contamination factors, the more important was the maintenance, information, quality control of water and hygienic conditions and conservation of reservoirs. The education in the health of involved persons was important for the maintenance and enlargement of the program.
