Calidad de agua de las subcuencas del río Quimi y Machinaza, caracterización de las subcuencas y análisis de la influencia antropogénica

Abstract

Abstract: This research was developed in the provinces of Zamora Chinchipe and Morona Santiago, its objective is to determine the water quality of the Quimi and Machinaza rivers and its anthropogenic influence, in addition to its morphometric characteristics. Through the determination of hydrographic parameters and the application of the methodology of the different quality indexes, the compliance with the maximum concentration limits established in the standards: TULSMA DCA 2015, TULSMA UA 2015, LMP-AC-Peru, LMP-DCA-Bolivia; the CCME and NSF water quality indices and Colombian contamination indices were calculated. The two sub-basins were characterized, revealing high concentrations of Mercury, Arsenic, Cyanide, Oils and greases, among the most prominent parameters that do not comply with the standards. The main conclusion is that the CCME method was the most appropriate for the analysis of the two sub-basins since it considers all the concentration data of the available databases, with "good to poor" classification, unlike the other methods, and with this information the quality maps were made.
