Abstract:
The Watershed of The Mirassol Stream is located in the city of São Paulo-Brazil, it suffers constant environmental degradation, due to the lack of involvement and interest from the local community and public management. The objective of this study is to provide a quality diagnosis of the stream waters. Water samples were collected in the months of August (dry season) and October (transition period) of 2018 and January (rainy season) of 2019, in three places called Points 1, 2 and 3. In order to understand the anthropic influences along the margins of the Mirassol Stream, Physical-chemical analyzes were carried out in situ and in laboratories to check the release of domestic effluents and their different concentrations in upstream and downstream areas. The results of the analyzes showed values above the parameters of domestic effluents: Total Ammonia, Total Sulphide, Total Phosphor and pH, mainly at the downstream areas. Based on the results, it was possible to verify the high concentration of pollutants and classify Mirassol Stream as Class IV, the worst classification for freshwater rivers, according to the Brazilian National Resolution for surface water - CONAMA Nr 357/2005.
