Abstract
The pollution of the Ganges River and Yamuna River has become a serious environmental challenge in India. Despite the implementation of several government initiatives aimed at river conservation, these rivers continue to receive large quantities of untreated industrial effluents, municipal sewage, and agricultural runoff. Such contamination has resulted in the degradation of aquatic ecosystems and poses significant health risks to millions of people who depend on these rivers for drinking water, irrigation, and other domestic purposes. The Yamuna River originates from the Yamunotri Glacier and flows approximately 1,376 km before joining the Ganges at Prayagraj. The river basin covers about 366,223 km² across several northern Indian states. The hydrological characteristics of the river vary considerably between monsoon and non-monsoon seasons, with nearly 80% of the annual flow occurring during the monsoon period. During the dry season, extensive diversion of water through barrages for irrigation, domestic supply, and industrial use significantly reduces the natural flow of the river. Pollution in the Yamuna River arises from both point and non-point sources, with domestic sewage representing the major contributor. A critically polluted stretch of approximately 580 km exists between the Wazirabad Barrage and the confluence with the Chambal River, with the 22 km stretch passing through Delhi being the most severely affected. Monitoring studies indicate that water quality is comparatively better in upstream regions but deteriorates sharply after the river enters Delhi. Elevated organic pollution, increased biochemical oxygen demand, and significant fluctuations in dissolved oxygen levels suggest severe contamination and persistent eutrophic conditions in this section of the river.
