The present study is conducted with
the purpose of determining the chemical characteristics of groundwater that
supplies 16 wells in the state of Coahuila, which are used for different human
activities. Sampling was conducted in January 2011. For 56% of the fifteen
wells tested, analysis did not detect the presence of aluminum; however, wells
2, 3, 6, 8 and 13 had concentrations above the permissible limit established by
the Mexican standard NOM-127-SSA1-1994. For cadmium, only the well 3 was above
the Norm. Meanwhile, iron was above the permissible limit in eight wells (2, 4,
5, 6, 9, 12, 13 and 15). Lead exceeded the limit in wells 6, 7, 9, 10, 11 and
