SUMMARY:

The Descoberto River, Ponte Alta Stream, Alagado River and the Santa Maria Stream are strategic for the Federal District (DF) and state of Goiás (GO) in Brazil, due to their importance for the depuration of effluents from Wastewater Treatment Plants (ETE) in the region and for the inflow of the Corumbá III and Corumbá IV reservoirs, the latter being an important source of urban water supply for DF and GO. This study analyzed the water quality in these transboundary rivers through compliance with the framing according to the Resolution CRH-DF No. 01 from 2014, and the Water Quality Index (IQA) and Framing Conformity Index (ICE). In general, the IQA results obtained positive quality levels, except for the Descoberto River, which reached the “Poor” level between 2017 and 2018. The ICE of the Descoberto River and of the Ponte Alta Stream reached the “Away” value. The Thermotolerant Coliforms and Total Phosphorus parameters were problematic for all water bodies. The results demonstrate the need for actions to improve water quality of these rivers and achieve the framing goals by 2030, given the challenge of urban expansion in these watersheds.
