Evaluación de la calidad del agua del río Yuquipa, tramo - comunidad Sagrado Corazón, mediante la identificación de macroinvertebrados bentónicos

Abstract

The objective of this study was to evaluate the water quality from Yuquipa River, stretch - Sagrado Corazón community by identifying benthic macroinvertebrates. A qualitative-quantitative research approach was applied. The bioindicator method was used, with the identification of benthic macroinvertebrates and the National Sanitation Foundation (NSF) quality index using the IOAData Software the habitat of this section and the riverbed were determined using the River Habitat Index (IHF). For the evaluation of water quality, biological monitoring of benthic macroinvertebrates was used applied the Biological Monitoring Party Index (BMWP/Col) and the water quality index. Variables were obtained through sampling points at different stations along the Yuquipa River stretch assessing the aquatic deterioration and environmental impact. As a result, the water quality in stations PY-1 and PY-2 is Regular in the three months of study; In the PY-3 station in November 2020 and January 2021, the quality is Good, while in December it is Regular due to runoff and carry-over of pollutants effects of seasonal rains. From the evaluation of the fluvial habitat, a Good quality level was determined, presenting the lowest level of 46 in the PY-1 station. The BMWP/Col monitoring determined an Acceptable quality (Class II) in stations PY-1 and PY-2, and a Good quality (Class I) in PY-3. The presence of 18 macroinvertebrate families was identified in close relationship with the quality index to their survival and adaptability. Finally, it is recommended to create a sustainable sewerage system with a higher circuit load to treat this wastewater and return the water to its cause. Also, a conservation plan for the Yuquipa River and a digital repository are suggested.
