Análisis de calidad de agua del río Tabacay a través de macroinvertebrados acuáticos

Abstract

There are several reasons to analyze the water quality of a river, since it is considered one of the most important resources for ecosystems and the health of a population; For this reason, the analysis of the physical, chemical and biological conditions are essential to determine its status and its possible uses. The primary objective of this work is to establish the quality of the water in the Tabacay River, according to the existence of aquatic macroinvertebrates, through the Biological Monitoring Working Party (BMWP) methodology, which provides an established score to the different organisms found in the area, the same ones that serve as bioindicators to establish the condition of the water. It is very important to highlight that the analysis carried out was based on the samples obtained in the field for later identification of the order and family to which each organism belongs, in order to determine the quality of the river water. The results achieved include an analysis of each of the areas studied, both in the upper, middle and lower areas. In the lower zone, according to the applied methodology, a score of 79 was obtained, which is equivalent to an acceptable water quality, in the middle zone of the river, 84 points were obtained, giving an acceptable water quality, and while in the upper area of ​​the river, 97 points were obtained, resulting in acceptable water quality.
