Study of water quality in sections of the Paguey River using aquatic macroinvertebrates

Abstract

This study constitutes a preliminary analysis of the water quality present in three stretches of the Pagüey River (Nilo-Cundinamarca) using aquatic macroinvertebrates as a bioindicator group. The collection was carried out on April 23, 2013, at the outlet of the In-Depth Module I: Hydrobiological Resources of the Environmental Engineering program, University of Cundinamarca, Girardot Section. A total of the classes Gastropoda were recorded with the order Basommatophora and the family Lymnaeidae and Insects, with eight orders and 17 families. The BMWP´Col analysis determined a water class II for all stretches, with acceptable quality and slightly contaminated. However, the Jaccard Classification analysis showed a decrease in terms of the aquatic macroinvertebrate community present in stretch 3, Balneario known as el charco de la Mula.
