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.
s o Jorge溪流微盆地位于塔拉贝- sp市，分为农村和城市地区，有畜牧活动、住宅和商业建筑，以及面粉工业。人类的干预一直在改变水资源，因此有必要对其进行监测并查明负面变化。因此，为了分析该微流域的水质，我们分析了pH值、化学需氧量、浊度、电导率和氮含量，以检查是否与立法存在分歧。将结果与CONAMA 357/2000进行比较，可以发现与工业更接近的样品中的差异(4)。对溪流的定性分析使人们有可能了解微盆地中有多少干扰对其水质产生负面影响;它们通常不可见或不易识别，但它们的存在改变了水的特性。
