Abstract: The assessment of water quality for human consumption is of utmost importance due to the crucial role water plays in public health. Therefore, the objective of this study was to evaluate the quality of water for human consumption in the municipality of Manicoré/AM. A survey of the semi-artesian wells supplying the city was conducted. The sampling took place during the rainy season, and six sampling points were selected, where the following parameters were determined: a) microbiological: thermotolerant coliforms and total coliforms; b) physical: apparent color and turbidity; c) chemical: Total iron and total manganese. After laboratory analyses, the results were compared with the values established by ordinance No. 888/2021 of the Ministry of Health. The results indicated that point 6, located in the Santa Luzia neighborhood, revealed the presence of total and thermotolerant coliforms, as well as values above the maximum contaminant level for apparent color and turbidity. Point 1, located at the Municipal Guard station in the Manicorezinho neighborhood, also indicated the presence of total coliforms. The evaluation of the parameters of the two sampling points (1 and 6) demonstrated that the water from the wells is unsuitable for human consumption.
