Effluents from a paper factory in Ethiopia are polluting the Upper Awash River. The factory's untreated wastewater has high levels of pollutants like BOD5, COD, TSS, and TDS. Even after treatment, the effluent still contains harmful substances like nitrogen and phosphorus. The river downstream is also contaminated, with levels of pollutants exceeding safe limits set by the WHO. The factory is not meeting the required discharge standards, and the river is highly polluted due to the effluent discharge.
