Objective: This study aimed to analyze the limnological and microbiological parameters of water from the Xingu River to establish a water quality profile for municipalities in the Xingu and Transamazon regions affected by the Belo Monte Hydroelectric Power Plant (BMHPP). Methods: A field study employing both qualitative and quantitative approaches was conducted to assess water quality parameters in stretches of the Xingu River within the affected municipalities. The analysis was guided by the limits established in National Environment Council (CONAMA) Resolution No. 357/2005. Results: The water samples collected across the study area complied with CONAMA standards for physicochemical (limnological) parameters. However, microbiological analyses revealed contamination levels that exceeded the permitted thresholds. Conclusion: Although the physicochemical parameters remain within regulatory limits, the microbiological results indicate elevated concentrations of E. coli and total coliforms, significantly surpassing the maximum allowable values for bathing water quality. These findings underscore potential public health and environmental risks in the region.
