The measurement of the values of arsenic and fluoride becomes critical in the characterization of groundwater quality. Although there are anthropogenic sources, most large-scale pollution in groundwater have been documented of geological origin, the arsenic to the reaction of oxidation in sulfide minerals in metasedimentary rocks and the F- value is proportional to the degree of water-rock interaction with fluorite (CaF2), the concentration values are proportional to residence times in aquifers and generally are associated with regional flow systems. The objective of this research was to determine the current correlation of arsenic and fluoride with emphasis in the extraction points used for human consumption, due to the water-rock interaction in a semiarid region in México. © 2016 The Authors.
