The situation of Canelón Chico creek was evaluated in three different study sites: before (Cascadita de los Monjes), next (Parque Artigas) and after Canelones city (Pacífico creek), with the aim of verifying whether the activities of the inhabitants of this city affect the quality of freshwater of the mentioned stream in the same way.
This unique monthly assessment was done using MACROINVERTEBRATES as these beings are BIOINDICATORS of water quality according to their level of sensitivity. This level is on a scale of 1 to 10, corresponding 1 to the strongest beings and 10 to the most sensitive. The findings were supplemented with water physicochemical measurements (pH, transparency and temperature) using GLOBE protocols.
In the three different sampling sites three repetitions were performed. At the end of the monitoring and after establishing correlations among the variables evaluated, it is concluded that water quality in PACIFICO creek could be better for life of macroinvertebrates as it presents a greater number of individuals and species.
The results of this research will serve to raise awareness among residents of the area of influence of the creek, communicating the research results through different means.
