From hydraulic and physicochemical data of groundwater, superficial and meteoric water collected from 1996 to 2005 in the Valley of Leon, the importance of the flow in the zone fault is corroborated; which can originate a preferential movement of the ground water, generating a hydraulic conduct that could be forming part of the recharge to the Valley. The zone of this research is located in the west part of the municipality of Leon, Guanajuato; and encompasses a constituted portion of basalt, sand-argillaceous tuff, gravel and andesite, mainly. The layer foundation is constituted by lava and tuffs. It can be considered that this portion works as an important recharge zone for the Valley. This zone has been over exploited for agriculture and industrial use.
