EVALUACIÓN DE LA CALIDAD DEL AGUA DEL RÍO CHAMBO EN EL TRAMO COMPRENDIDO DE LA UNIÓN DEL RIO CHIBUNGA HASTA CAHUAJI BAJO, PROVINCIA DE CHIMBORAZO, 2015

Abstract

The Water Quality Index (ICA) proposed by Rojas (1991), to assess the state of water in the basin of the river Chambo on the stretch of River Union Chibunga to low Cahuaji 2015, during the rainy season was applied. To calculate the ICA Rojas (1991) 5 points were analyzed along the river. The selected parameters were: pH, dissolved oxygen, biochemical oxygen demand five days (BOD5), fecal coliform, suspended solids, as well as other parameters were analyzed: cadmium, lead, phosphorus, oils and fats, nitrates and surfactants. The water quality of the studied area according to the result of ICA Index Rojas is located in the strip corresponding to the acceptable category within the range corresponding to 51-70, but the results of the parameters (lead, phosphorus, fecal coliforms and oils and fat) determine that these values are outside the limits specified in the Ministerial Agreement 028. Other Water Quality Index to fit the realities of the place, with specific conditions and parameters vital importance of the sector is recommended.
