Evaluación de la calidad del agua del río Santa Clara ubicado en el cantón Rumiñahui.

Abstract

Demographic growth modifies the environment of a place changing environmental factors, even water resources that are necessary for animal life development. Therefore, it is important to maintain water bodies in proper conditions through the regulations established to control pollution. The objective of this project was to determine the water quality of the Santa Clara River, located in the Rumiñahui canton in order to categorize the degree of compliance with the current environmental regulations TULSMA (2015), Annex 1, Book VI, Table 3. Subsequently, a sampling plan was elaborated and conducted between June and July 2021, where in situ analyses were performed, as well as analyses of physical, chemical and microbiological parameters that were developed in certified laboratories. The results were used to determine the Water Quality Index (WQI), which in most sections of the Santa Clara River showed a WQI between 40 and 50 that corresponds to regular and poor characteristics. Based on the maximum permissible limits presented in the TULSMA (2015), Annex 1, Book VI, Table 3 it presented that there are parameters outside the norm, such as fecal coliforms and dissolved oxygen. Finally, to reduce the environmental impacts on the riverbed, a mitigation plan was proposed based on three axis: reduction of solid waste, monitoring of wastewater discharges and community participation in the care of the Santa Clara River.
