Análise da água bruta da bacia do rio Montes Claros, manancial da cidade de Campos Belos (GO) de 2010 à 2024

Abstract

In recent decades, assessing the quality of water intended for human consumption has become a cha lenge for al those involved in ensuring the accessibility and availability of drinking water. The emergence of new chemical compounds (such as organic and inorganic products, and pesticides) associated with improper management by human activities, and even their natural composition in the soil along areas close to water reserves (surface or groundwater), can contribute to increased levels of contamination and pollution and pose potential health risks to consumers. In this context, it is important to analyze the water quality indices of large and smal river basins that supply a large population. The Montes Claros River, a microbasin located in northeastern Goiás, is of great importance as the primary available natural resource and supplies the municipality of Campos Belos, Goiás. Using raw water data from the source provided by the Goiás State water supply company - SANEAGO S/A, and using geochemistry and geomedicine studies, advances and modernization of water treatment techniques supported by relevant legislation (such as ordinances 518/2004; 2914/2011; 888/2021 of the Ministry of Health and resolution 357/2005 of CONAMA) were essential for the analysis of the quality of the raw water of the Montes Claros River, which presented, in its vast majority, physical-chemical, biological, microbiological, organic, inorganic, agrochemical, disinfection product and cyanobacteria parameters in accordance with the maximum permitted values (VMP) established by the potability standard, with the exception only of the apparent color (caused by excess organic matter) and turbidity (with an increase in cases mainly during rainy periods), in the specific cases of the levels of Total coliforms and Escherichia coli in the Montes Claros River are normal due to the fact that the research analyzes the parameters in raw water and not in treated water (in this case it should be absent in 100 mL
