(Universidad de Cuenca, 2013-06) Beltrán, Alberto; Mendieta, Paul; Vanegas, Juan
This research shows us specifically the contaminants in the Tarqui river located on the outskirts of Cuenca city. The parameters used to determine the water quality of the river were: DBO5 , fecal coliforms, water quality (Physical-Chemical), and the biotic index. The samples were taken at 8 different stations (1 station at the Portete River, 1 station at the Irquis River, 5 stations at the Tarqui River, and 1 station at the Cumbe River). What refers to DBO5 the samples are into the range of clean water; about the fecal coliforms were obtained bad results because of the intensive livestock in the area; the quality index that represents the condition throughout the river has label of good finally the biotic index indicates that the river´s healtn has a regular condition. These data reflects stability in the Tarqui River´s health except in the Cumbe River´s area where peaks of contamination appear.
