It was make the map of contamination risk of groundwater at a scale of 1: 100 000, integrating the map of natural vulnerability of this basin obtained by the RISK method, and the map of the hazard index of polluting sources prepared according to the methodology developed by the COST Action 620. The results show that a moderate and low risk level predominates, although were defined sectors with high and very high risk of contamination.
