Sumario:The present work presents the assessment of the vulnerability and risk of groundwater pollution in the eastern portion of the Araripe Sedimentary Basin, Ceará, Brasil, through the GOD and POSH methods. The GOD method presented three classes of vulnerability: low, moderate and high, with a predominance of moderate vulnerability (80%). The POSH method classified the pollutant loads into three indexes: high, moderate and low. The vulnerability map associated with the risks of pollution facilitated the identification of the areas most susceptible to contamination, serving as a subsidy for municipal managers in future plans for use and occupation of urban and rural land.
