Water is a fundamental natural resource for life, for economic development and for social well-being, having a infinity of uses, from the simplest to the most complex. However, it has gradually become a scarce resource that needs to be cared for with discernment. The quantity and quality of fresh water on the planet has always been essential to maintain life cycles, the biodiversity of organisms and the survival of the human species. It is necessary to know the quality of the water to determine what possible uses can be attributed to it. In this context, the present study had as its object the evaluation of the quality of the water that is sent to the environmental reserve, preserved by the State Institute of Forests (SIF), entitled Mata dos Ausentes Ecological Station (MAES). The study was carried out based on the collection of samples during drought and rainy season. The samples were collected at five points in which the study of the flow was carried out, as well as the physico-chemical parameters: Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), pH, Hardness, Turbidity, Nitrates, Chlorides, Manganese and Iron. At the end of the analyzes, a comparison was made of the results obtained with the flow rates at the sample points. It was possible to notice that, despite having a low flow, which negatively influences the autodepuration of the rivers, the parameters analyzed are mostly with values allowed by law.
