Análise retrospectiva dos padrões de qualidade da água bruta, tratada e distribuída pela estação de tratamento de água bom jardim, em Uberlândia, Minas Gerais, nos anos de 2019 a 2023

Abstract

Approximately 90% of the Brazilian population lives in urban areas. In this context, access to treated water and its quality control are essential elements for the promotion of public health. This study analyzes the variations in water quality parameters used in the urban water supply of Uberlandia, Minas Gerais, sourced from the Ribeirao Bom Jardim. It is a retrospective and descriptive study with a quantitative approach, based on the evaluation of physicochemical parameters such as residual chlorine, apparent color, pH, turbidity, and fluoride in water samples collected from Ribeirao Bom Jardim, treated and distributed by the Municipal Department of Water and Sewage (DMAE) of Uberlandia, from 2019 to 2023. The evaluated water quality parameters were found to be within the limits established by Brazilian legislation for treated and distributed water, considering that current regulations do not provide specific standards for raw water. A slight reduction in the quality of distributed water compared to treated water was observed, particularly in relation to the turbidity parameter. Additionally, changes in raw water parameters were detected between September and February, a period characterized by higher rainfall, which contributed to increased turbidity and apparent color. Despite the significant variation in chemical parameters caused by the region's climatic seasonality, the water supplied from Ribeirao Bom Jardim and treated at the Bom Jardim Water Treatment Plant met the potability standards established by legislation, according to the data analyzed for the period from 2019 to 2023.
