Objective: To determine the presence of bacterial human pathogens in irrigation water of the savannah of Bogota high watershed. Materials and methods: Samples were collected from 8 municipalities, 8 of which were randomly selected for a number of tests including detection of total coliforms via filtration membrane, Most Probable Number (MPN) for fecal coliforms; isolation on selective media and biochemical identification using the BD-BBL CRYSTAL system. Results: Direct or diffuse fecal contamination approached 41.7% of selected samples while aquatic-terrestrial normal flora the remaining 58.3%. According to the percentage of E.coli and count of total coliforms, the analyzed water is not suitable for agricultural use and represents a risk for human health.
