Qualidade da água superficial de nascentes em zona urbana consolidada Sinop, MT

Abstract

Due to urban expansion, the quality and preservation conditions of the present water resources are put under pressure, due to the vegetative suppression, the conditions of use and occupation of the soil and the contribution of liquid and solid waste, to the hydrous body. Therefore, the present work aims to analyze the water quality of springs in a consolidated urban area of Sinop-MT. For this purpose, we sought to evaluate the physical-chemical and microbiological conditions in four springs, through field measurements and laboratory analysis, of eleven qualitative parameters. The results showed, differences in the values of thermotolerant coliforms, biochemical oxygen demand, and dissolved oxygen between points and over the period of collections, presenting aquatic environments that have suffered some typing of impact, putting at risk the survival of water fauna and subject to the development of unwanted vegetative and microbiological species. Through the quality answers, it concludes that the physical-chemical aspects present good conditions; however, when the biological parameters are analyzed, they result in altered environments that need technical monitoring, awareness-raising activities, and preservation of the springs and the surrounding environment.
