Evaluación fisicoquímica y microbiológica del agua destinada al consumo humano para la demostración de su calidad e inocuidad

Abstract

One of the most important natural resources for living beings is water, since it serves us for different activities such as human consumption, agriculture, livestock, among others. Therefore, it is of great importance to know if this resource is of quality at the time of consumption, for this, there is a bromatological analysis, which allows us to evaluate a product, in this case water, and to know its physicochemical and microbiological characteristics. The objective of this research is to evaluate the physicochemical and microbiological quality of the water used in human consumption for the demonstration of its quality and safety, and to fulfill the objective, a bibliographical research and data collection was carried out that allowed us to know the water quality in some cities of Ecuador such as Guayaquil, Quevedo, Manabí, Quito, and the Ecuadorian ecological corridor, as well as cities in Peru such as Umuto and Trujillo. Physical (turbidity, pH, hardness, color, temperature), chemical (residual chlorine, nitrites, chlorides), and microbiological (total and fecal coliform) parameters were evaluated, taking INEN and OMS standards as reference. Finally, it was possible to demonstrate that the water for consumption that meets the standards is that of the following locations: in Ecuador we have Guayaquil and Quito, while in Peru the town of Laredo - Trujillo, the rest presented unsatisfactory results. that did not allow to guarantee its quality.
