A Water Quality Index for the Black Water Rivers of the Amazon Region
A water quality index has not been developed for Amazonian blackwater rivers. In this paper, we used data collected in recent years to address this gap. An index was constructed using, in total, 342,930 analyses involving 161 water quality parameters. All analyses were part of ten large-scale campaigns, which took place between 2021 and 2023. The modifications proposed by the adoption of the new WQI enabled changes in the water quality results of the Amazon region, in comparison with an index used in other parts of Brazil. The proposal is a long-awaited tool that can significantly assist in the next stage in the preservation of this vast national wealth, which is the Amazon basin.
