Abstract: Population growth linked to greater exploitation of nature compromises the quality of water, which is considered a limited natural resource and is vitally important for the survival of living organisms and directly influences the economy, leisure, culture and the social environment. This study evaluated the physicochemical, toxicological and microbiological parameters of rivers and streams in the municipality of Barcarena, State of PA, Amazonia, Brazil. We collected 58 samples in the period from 2021 to 2022. The average values verified were above the limits allowed by Brazilian legislation (CONAMA 357/2005) for true color (µ = 218.09 ± 223.843), BOD (µ = 31.30 ± 64.992) and Escherichia coli (µ = 1243.76 ± 2838.743) in stream samples when compared to those from the river, demonstrating that there are statistical differences in these parameters between these two environments. We also analyzed traces of 10 toxic metals (Al, B, Ba, Be, Cd, Co, Cr, Cu, Li, Pb). The average levels of these pollutants ranged from 0 (
