Pollution of river water by the discharge of untreated industrial and domestic wastewater poses a severe threat to aquatic ecosystems and human health. When untreated sewage, rich in harmful chemicals, heavy metals, and organic pollutants, is directly released into rivers, it depletes oxygen levels, disrupts aquatic biodiversity, and contaminates drinking water sources. This not only endangers marine life but also increases the risk of waterborne diseases in communities relying on these rivers for daily use. Addressing this issue requires urgent implementation of advanced wastewater treatment technologies, strict enforcement of environmental regulations, and public awareness campaigns to promote sustainable water management practices.
