Abstract
Description
The Santa Monica creek is the main source of the Nitrera reservoir, which supplies the drinking water to the municipality of Concordia. To determine the quality of the water in the Creek, and if it accomplish the standards, a physical-chemical and biological characterization was carried out using aquatic macroinvertebrates as bioindicators. Physical-chemical and hydro-biological samples were taken at three stations in the creek during three campaigns in 2017. The physicochemical results presented a slight spatial-temporal variation, and we determined that November presented the highest abundance and richness values of macroinvertebrates, being Phylloicus the predominant taxa. The BWWP/Col index values were between 52 and 119. Santa Mónica Creek has a good water quality, and most of the physical-chemical parameters accomplish the regulations to be a source for drinkable water supply.
La Quebrada Santa Mónica es la fuente con el mayor aporte de agua al embalse la Nitrera, que abastece el consumo al municipio de Concordia, Antioquia; con el objetivo de conocer calidad de agua de la Quebrada y determinar si cumple con los criterios de calidad, se realizó la caracterización fisicoquímica y biológica empleando los macroinvertebrados acuáticos como bioindicadores. En tres estaciones de la quebrada, se tomaron muestras fisicoquímicas e hidrobiológicas durante tres campañas en el año 2017. Los resultados fisicoquímicos presentaron una variación espaciotemporal leve, se pudo determinar que el mes de noviembre se presentó el valor más alto de abundancia y riqueza de macroinvertebrados, siendo Phylloicus el taxa predominante. El índice BWWP/Col estuvo entre 52 y 119. La Quebrada Santa Mónica presenta una buena calidad de agua y la mayoría de los parámetros fisicoquímicos cumplen con la normatividad para ser fuente de abastecimiento de agua potable.   The Santa Monica creek is the main source of the Nitrera reservoir, which supplies the drinking water to the municipality of Concordia.
