摘要：This paper aims to present the estimate of the natural vulnerability and risk of soils, in the areas of the Guarani aquifer’s recharge, in the State of Goiás (SAG/GOIÁS). To establish the classes of vulnerability of these soils, the lands map of declivity was crossed with the hydraulic conductivity one, and the following classes were obtained: low, moderate, high and very high. It was evaluated that 45% of the recharge areas has very high vulnerability, and 47% are considered high class, togheter these areas represent more than 90% of the total area of occurrence of the Guarani aquifer in the State of Goiás which inspires specific care in regards of use and handling of the lands. 32,8% of the recharge areas has high risk and 27,5% has very high risk, 60% of the total of the area. Key-words: Guarani Aquifer. Vulnerability. Risk of contamination.
