Determination of water quality at a confluence. Jun Jun waterfall case

Abstract

The water quality is essential to ensure the welfare and progress of a locality, this research aims to evaluate the water quality of the Quero River, located in the canton of the same name, to determine the levels of contamination present was taken as a reference Ministerial Agreement 097-A, Annex I, Table 2, Table 3 and Table 5 respectively this was determined based on the uses of the resource. Two sampling points were taken as reference, the first one diagonal to the emergent cell and the second one downstream of the Jun Jun waterfall. It was determined that the water of the Quero River is optimal for the development of aquatic and wild life since it has high concentrations of dissolved oxygen plus 3 mg/l, obtaining maximum values of 7.4 mg/l, an indicator of good water quality, but regarding agricultural use, a high organic load is evident, especially at the diagonal point of the emergent cell where concentrations of 4300 NMP/100 ml are registered, This may indicate contamination by leachate, since it has a low concentration of fecal coliforms the 1000 NMP/100 ml, so as not to attribute the high concentrations to feces or slurry. Therefore, it is recommended that the water of the Quero River be used for agricultural use only upstream from the zone of the emerging cell, since the analyses show that the river is self-recovering.

Keywords: water quality, dissolved oxygen, total coliforms, emerging cell.
