Hydrogeochemical assessment and groundwater quality in a shallow aquifer: A case study of San Luis Potosí Valley, Mexico

Assessment of hydrogeochemistry in groundwater using water quality index model and indices approaches

“…However, the quality of surface water is rapidly declining day-by-day due to the direct discharge of effluents in waterbodies such as canal, rivers, estuaries and bays [ [ [6] , [7] , [8] , [9] ]]. Therefore, the groundwater resources have been utilizing as a major replenishable source of freshwater for human consumption, farming and industrial application around the world [ [ [10] , [11] , [12] , [13] ]]. At present, groundwater resources meet the global demand of drinking water by 65% and the need of irrigation water by 43% [ 14 ].…”
