ANÁLISE DE PARÂMETROS FÍSICO-QUÍMICOS DA ÁGUA DA MICROBACIA SÃO JORGE, TARABAI-SP

Abstract

The São Jorge stream micro basin, located in the municipality of Tarabai-SP, is divided into rural and urban areas, with the presence of livestock activities, residential and commercial buildings, as well as a flour industry. Human interference has been modifying water resources, making it necessary to monitor them and identify negative changes. Thus, in order to analyze the water quality of this micro-basin, pH, chemical oxygen demand, turbidity, electrical conductivity and nitrogen were analyzed to check for possible disagreements with the legislation. The results were compared to CONAMA 357/2000, which allowed to find discrepancies in the sample with greater proximity to the industry (4). The qualitative analysis of the stream made it possible to understand how much interference in the micro basininterferes negatively in thequality of its water; they are often not visible or easy to identify, but they are present altering the characteristics of the water.
