Análisis fisicoquímico y microbiológico del agua tratada de la junta de agua potable y saneamiento “La Paz”

Abstract

It has been shown that drinking water coverage in rural areas is only 53.07%, due to the fact that the main problem is the lack of community sanitation management. The objective of the study was to monitor the quality of treated water from the Junta de Agua Potable y Saneamiento “La Paz” located in the province of Azuay, Ecuador; based on the NTE INEN 1108:2020 standard, which does not have a purification and sewerage system that allows the water to be suitable for human consumption since only a chlorination process is carried out to supply 279 homes in the community. The research was observational, descriptive and cross-sectional. For the analysis, sampling was carried out in duplicate over a period of eight consecutive weeks, considering one sampling every weekend. The water samples were collected from the supply tank after the chlorination process (treated water), and the following physicochemical parameters were determined: color, odor, taste, turbidity, pH, free residual chlorine, nitrates, nitrites and microbiological parameters: total coliforms. The results obtained are presented in tables and bar graphs, which showed that the physicochemical parameters such as color, turbidity, nitrates, nitrites and microbiological parameters are within the limits. On the other hand, the pH values are below the minimum permitted range, and with respect to free residual chlorine, it was shown that it complies with 87.5% of what is indicated in the regulations.
