Evaluación Físico-Química y Microbiológica del agua de la Junta Administradora de Agua Potable de la parroquia Quisapincha, cantón Ambato, provincia Tungurahua.

Abstract

This research work aims to assess the physical, chemical, microbiological quality of potable water given by Junta Administradora de Agua Potable de Quisapincha (JAPAQ), in the city of Ambato, in the province of Tungurahua, before and after conventional treatment in order to determinate the safety and condition level for human consume. Nine sampling points were established in the period November-December 2015 where date collection was done in triplicate (every 15 days) which are part of the waterfall-Cerro Casahuala, water collection tank-Chuzalongo, tank previous sand entering filter- Colacucho, output tank of carbon filter- Pie de Pucará, storage tank- Pie de Pucará, north, south and central domiciliary distribution networks of JAPAQ. Procedure was carried out taking into account the parameters given by norm NTE INEN 1108:2014 for sampling, water quality control, sampling for microbiological exam and sample conservation. Physical, chemical, and microbiological parameters were determined (pH, color, smell, turbidity, temperature, total dissolved solids, conductivity, free residual chlorine, hardness, total iron, nitrates, nitrites, sulphate, phosphate, manganese, flour, ammonium, fecal and total coliforms) according to norm; including 27 samples for physical chemical analysis and 54 ones for microbiological analysis. It was determined that water given by JAPAQ does not fulfill the limits allowed by norms related to physical-chemical quality before and after conventional treatment; in the other hand the microbiological parameters were not achieved either before treatment. After conventional treatment all samples fulfilled microbiological parameters, however, physical-chemical parameters such as: color, total iron, and phosphates are not under the norm. it was concluded that water given by JAPAQ is not safety
