Abstract	In recharge areas the aquifer is free and, therefore, subject to contamination of effluents and tailings deposited on soils that cover it. Thus, it becomes crucial not only its protection at all levels, as the knowledge of its degree of natural vulnerability. The present work used geostatistics modeling techniques to study the natural vulnerability of the Guarani aquifer in the city of Rio Bonito, State of Sao Paulo, Brazil, where the Guarani aquifer is exposed. These techniques were adapted to develop a spatial classification of vulnerability indices in probabilistic terms. By ordinary kriging method maps of vulnerability classification were obtained. To determine the vulnerability of the aquifer was used the Aquifer Vulnerability Index (AVI), which requires knowledge of unsaturated zone thickness and permeability. The final product was a map with probabilistic index of vulnerability of the Guarani aquifer, which presented values between 0 to 0.33 years, framing the area studied in the extremely high vulnerability AVI class.
