Evaluación de Riesgos sobre la Calidad del Agua en el Acueducto Rural El Tobal, Subachoque, Cundinamarca; en el Marco del Plan de Seguridad del Agua

Abstract

In the present study, an assessment was made of the potential risks to the water quality of the supply source of the El Tobal rural aqueduct, under the guidelines proposed by the World Health Organization (WHO) for the elaboration of Water. A semiquantitative approach based on risk matrices (De Deere, 2001) adopted by WHO was followed to assess the biological, physical and microbiological hazards associated with the uptake that are affecting the Water safety; Then determined all the dangerous events that can contaminate the water, compromise its security or interrupt the supply; And subsequently assessed the risks associated with such events. It was possible to determine that the two dangerous events with the highest risk classification were livestock and agriculture as the ones that are most likely to occur and have adverse effects on human health. For the estimation of the water quality of the El Salitre Gully, three sampling points were taken, along its course, in order to perform an analysis of the physical-chemical and microbiological characteristics, observing non-compliance in 4 of the parameters Measured at maximum permissible values (turbidity, total coliforms, E. coli, iron), according to Resolution 2115 of 2007; As well as parameters suggested by the WHO water quality guidelines. As a tool for decision-making by the entity providing the service, a map was designed for each dangerous event where the properties were located with their respective risk classification according to what was found in the implementation of the property files and visits Of inspection.
