Because it is an unconfined aquifer and is relatively close to the surface, it becomes an easy target for infiltration of contaminants of various sources, such as pesticides and fertilizers, and also those related to human activities like leaking pipes, waste disposal and other substances from industrial activities and mining. The present work aims to study about the vulnerability of the soils on the north section of the Ribeirão Claro hydrografic basin, which covers almost the entire city of Rio Claro. A vulnerability map was created as the major product of this work, relating the geology and the use and occupation of the soil, in the area. Furthermore, fieldworks were conducted, in which in situ geotechnical testing was performed using the Guelph Permeameter, and deformed and undeformed soil samples were collected from all geological formations of the area, in order to perform laboratory geotechnical testing, to obtain the materials physical parameters, its grain size and sedimentation rate, and also its 6 permeability based on the varied load method. With the obtained results, it can be concluded that the hydraulic conductivity of the Rio Claro Formation's soils is heterogenous, a reflex of it's composition. The vulnerability for the aquifer area obtained in this work, is in general, high
