On August 6th, 2014, the event labelled as the "worst environmental disaster of the mining industry in Mexico" ocurred in the Sonora River, when Buenavista del Cobre mine spilled around 40,000 cubic meters of an acidic leachate. In order to expand our knowledge of the consequences of this event, the water quality monitoring data base was analyzed for groundwater from the Río Sonora trust fund webpage. Due to the health relevance of the spill, the reported data was compared to the established maximum allowance values of Mexican regulations. Furthermore, for an enhanced discussion, the case of arsenic was also analyzed, comparing the data with Mexican regulations as well as with the WHO guidelines for drinking water
