The territory of México is made up by two thirds arid and semiarid ecosystems, which influences the quantity and quality of water that infiltrates and reaches aquifers; likewise, the elements present in the water are the result of processes of chemical weathering of the rocks in contact with the water. The objective was to determine the quality of water for agricultural irrigation in the underground water, for which 15 points of sampling were selected that included waterwheels, wells and springs, defining with the Riverside norms the calculation of the relationship of sodium adsorption and, using the Wilcox method of sodium %, where in general terms 46.6 % of the samples of water were of good quality for agricultural irrigation, and 13.3 % presented a doubtful to mediocre quality, which is why it is not recommended for use in agricultural irrigation.
