Conteúdo: 	The absence of strategies for sustainable use and management of hydric resources is probably the main reason of several negative environmental impacts. Among them we can point out the inadequate use of pesticides on crop fields located over vulnerable areas. Due to this, the assessment of water risk contamination potential in aquifers has extreme importance to drive practices in order to reduce undesirable contaminations. In the present work we use CMLS-94 simulator to evaluate the vertical movement of pesticides through soils in agricultural catchments over areas of aquifers in Brazil. 2-4D acid, dimethoate, prochloraz, methamidophos and carbendazim applied in yellow passion fruit were studied in loamy/clayey kaolinitic, isohyperthermic Typic Hapludult, sandy/loamy, kaolinitic, isohyperthermic Typic Hapludult, and loamy, oxidic, isohyperthermic Typic Kandiustox soils at the Igarapé Cumarú catchment, Pará State, where Pós-Barreira Aquifer is present. Additionally we studied the movement of hexazinone applied in sugarcane field crop in a Typic Eutrorthox soil in the Esparaiado catchment, where Guarani aquifer is present. The results of this study helped to prioritize local monitoring in terms of surface and groundwater pesticides contamination potential, as well as, that none of the studied pesticides presented any potential to contaminate the aquifers, when considered the evaluated scenarios.
