Abstract

In northeast Mexico is Linares City, which has an extensive agricultural\backslashnarea and many industrial activities. Near this city is the Cerro-Prieto\backslashnDam (similar to 12 km NE direction); this drinking water reservoir\backslashncaptures the water of the Pablillo River catchment area and constitutes\backslashnan important source of potable water for the metropolitan area of\backslashnMonterrey, the largest urban center of this region. Groundwater sources\backslashnin this area provide drinking water to Linares inhabitants. A\backslashnhydrogeological and hydrochemical study was conducted on the shallow\backslashnaquifers surrounding the urban centers (Linares and Hualahuises) to\backslashndetermine the evolution of the water quality between 1981 and 2009. The\backslashnhydrochemistry was assessed upgradient and downgradient from the\backslashnpotential contamination sources in Linares city. Groundwater showed a\backslashnchemical evolution from calcium-bicarbonate type to\backslashncalcium-sodium-sulfate type. The water qualities in the downstream area\backslashnafter Linares are inferior compared to the upstream area before the\backslashncity. Nitrate concentrations in groundwater increased significantly\backslashnafter 28 years indicating an important pollutant process in this period\backslashnof time over the study area. The possible pollution sources could be the\backslashnagricultural and farm activities, industrial development, landfills\backslashnleachate, septic tanks and wastewater of municipal and domestic\backslashnconsumption. If the present scenario continues, an aquifer vulnerability\backslashnassessment would be important for the sustainable water management.
