Monitoramento da qualidade físico-química da água do rio Bacacheri, Curitiba – Paraná - Brasil

The disorderly growth of the city of Curitiba, capital of the state of Paraná (Brazil), has led to an increase in anthropogenic actions on most of its urban rivers, such as the discharge of in natura wastewater, the dumping of domestic and industrial waste, the alteration of its body water and the deforestation of the riparian forest, which eventually determined the degradation of these water bodies. The Bacacheri River, one of the most impacted rivers in the urban area of Curitiba, has its source in the Cachoeira district, located in the northern region of the city, crossing 16 neighborhoods along its 12 km of length. In this context, the objective of the present study was to investigate the water quality of the Bacacheri river through physico-chemical parameters in four (04) different harvest points between June and November (except August) of 2016. The results have been shown that in the areas closer to its source and its mouth, the Bacacheri river is easily biodegradable and in its intermediate areas it is more degradable than the other harvest points. Although its turbidity is below the limit established by the Brazilian guidelines which provides for the control and surveillance procedures of water quality for human consumption and its potability standard (Health Ministry Legislation number 2.914 / 2011), the other results indicate that It deals with a polluted river, and the intervention of competent government agencies is necessary to enable the pollution of this river.
