Índices de calidad de agua mediante metodologías UWQI (Universal Water Quality Índex) y CWQI (Canadian Water Quality Índex), caso de estudio río Calera y Amarillo

Abstract

Abstract:This work aims to apply the UWQI (Universal Water Quality Index) and CWQI (Canadian Water Quality Index) methodologies to determine the water quality in the Calera and Amarillo rivers. For the development of the UWQI methodology, the Delphi technique was used to obtain the weights of the parameters to be evaluated and, for the subscript values, the Ecuadorian standard on water quality regulations for discharges established in the TEXT was used. UNIFIED SECONDARY ENVIRONMENTAL LEGISLATION (TULSMA), for the preservation of aquatic life in surface waters. The methodologies used a database from a period 2001 - 2014 with analysis results of water samples taken at 14 monitoring points located within the basin. Applying these two methodologies, the water quality index was calculated for each monitoring point and the general state of these water bodies was obtained; obtaining as a result that the state of the water in these tributaries is poor.
