Water quality in the central zone of the Texcoco aquifer, Mexico

Objective: To determine water quality in the central zone of Texcoco aquifer, Mexico, for human use and consumption agricultural use. Methodology: The physical, chemical, biological indicators from 16 wells urban areas aquifer were determined. sampling was carried out, based on parameters definition per established current official Mexican standards. Results: According to physical concentrations CO32-, HCO3-, Ca2+, Mg2+, Cl-, SO42-, PO43-, Na+, K+, Fe, Cu, Zn, sample suitable Based cadmium (Cd) concentration, unsuitable use, 12 6 wells, respectively. lead (Pb) studied; however, it any wells. In eight analyzed, presence fecal coliforms lower than permissible limit Implications: This study complements researches done other aquifer. causes pollution are unknown about vulnerability possible polluting sources should be out. Conclusions: has limitations as a consequence high Cd Pb its microbiological quality.
