The Desierto de los Leones National Park is a place that features recreational activities for residents and visitors to Mexico City. The Presa de los Patos Ducks Dam is one of the many bodies of water that are present in the park. By means of physico-chemical and microbiological analysis, it was determined that the water of the Presa de los Patos cannot be considered potable. The pH range was between 5.5 - 5.9. The turbidity exceeded the values established in the standards 10.7 - 32.3 Nephelometric Turbidity Units NTU’s. Chemical Oxygen Demand COD showed that large amounts of oxygen are needed to oxidize organic matter 106 - 450 mg-L. The amount of coliforms and fecal coliforms exceeds the values established by the standards used total coliforms 98 - 956 Colony Forming Units CFU’s, fecal coliforms 78 - 807 CFU’s. Five bacterial genera Escherichia coli, Pseudomona, Klebsiella, Shigella and Salmonella were isolated and identified. Most of the bacteria isolated were resistant to ampicillin 90%, while 25% were resistant to ciprofloxacin. The water consumption of the Presa de los Patos is a great risk for the habitants and visitors of the park.
