          Abstract

          RESUMEN La subcuenca del Río Teusacá presenta alta actividad urbanística e industrial en, aproximadamente, el 50% de su superficie, lo cual, ha generado vertimientos de aguas residuales al ambiente acuático. El objetivo de este estudio fue caracterizar la calidad del agua, con base en el Índice Biótico de Familias (IBF), en dos sectores (alto y bajo) del río, en dos temporadas (seca y lluviosa) y analizar la correlación del IBF con: COT, fosfatos, sulfatos, nitratos, nitritos e índices de diversidad. Los muestreos, se realizaron con una red Surber (malla 500 micras y 0,09m2 de área), en 10 sitios, distribuidos en el curso principal: en octubre de 2016, al finalizar una temporada seca y en julio de 2017, al terminar una temporada lluviosa. En total, se registraron 35 taxones y los órdenes con más familias fueron: Diptera (28%), Coleoptera (17%) y Hemiptera (11%). El IBF presentó correlación positiva (>76%) con los contaminantes químicos y se observó que los principales contaminantes del río fueron los fosfatos y el COT, mientras que el IBF con los índices de diversidad, no mostró correlación. La calidad del agua en el sector alto del río estuvo entre buena y regular en ambas temporadas, mientras que en el sector bajo estuvo entre malsana y muy nociva. Estos resultados sugieren que en IBF es un buen indicador de la calidad de agua en los ríos.

          ABSTRACT The Teusacá River subbasin presents high industrial and urbanization activities in approximately 50% of its surface, which has generated discharges of waste water and pollutants into the aquatic environment. The aim of this study was to characterize the quality of water based on the insect family biotic index (FBI) in two river sectors (low and high) in two seasons (dry and rainy) and to analyze the FBI correlation with: TOC, phosphates sulphates, nitrates, nitrites and diversity indices. Sampling was carried out in October 2016 and in July 2017 at the end of the dry season and the rainy season, repectively, using a Surber net (500 microns and 0.09m2) at 10 sites, distributed along in the main course of the river. A total of 35 taxa were recorded, the groups with more families were: Diptera (28%), Coleoptera (17%) and Hemiptera (11%). The IBF was significantly and positively correlated with chemical pollutants (>76%) and the main pollutants of the River observed were phosphates and the TOC; while the IBF was not correlated with the diversity indices. The water quality in the high river sector was between good and regular in both seasons; while in the lower river sector it was very harmful and unhealthy. The results obtained suggest that the FBI is an appropriate indicator for determining the water quality of the river.
