Evaluación de la calidad del agua mediante el uso de macroinvertebrados acuáticos y pruebas fisicoquímicas en la quebrada Jurado, Pamplona, Norte de Santander- Colombia.

Abstract

The study of aquatic macroinvertebrate diversity was conducted in the Quebrada Jurado, located in Pamplona, Norte de Santander, between August and September 2024. Three sampling stations were analyzed, resulting in the collection of a total of 36 families and 14 orders of macroinvertebrates. During the investigation, various physicochemical parameters of the water were considered, including dissolved oxygen, pH, turbidity, total solids, chemical oxygen demand (COD), and biochemical oxygen demand (BOD5). The results showed variability in the composition and abundance of macroinvertebrate communities across the studied stations, allowing for the identification of diversity patterns related to environmental conditions. Stations E1 and E3 exhibited similar characteristics, while E2 stood out due to significant differences in physicochemical parameters and greater biological diversity. This research highlighted the importance of macroinvertebrates as sensitive indicators of variations in water physicochemical factors. Additionally, it was observed that domestic and agricultural pollution influenced the abundance and diversity of present species. This study provides key information for the conservation and management of aquatic ecosystems in the region, emphasizing the value of macroinvertebrates as effective tools for assessing water quality in river systems. It underscores their role as natural indicators of water quality, offering essential information for the conservation of local aquatic ecosystems and promoting a more sustainable approach to managing our water resources.
