The river Yamuna; once considered one of the most important rivers in India and the largest tributary of the sacred River Ganges has become one of the main reasons for health hazards for humans as well as aquatic life. Various cities like Delhi, Mathura, Agra etc located on the banks of the river Yamuna receive contaminated water, since the water in these areas have become extremely polluted.
One of the main reasons for such deterioration is the inflow of unhygienic and dirty water from nearby drains, open barrages and sewage into the river. The dissolved oxygen content into the river has almost being reduced to zero, which is a big threat for marine life. Thousands of fish have been found floating dead along the banks of Yamuna between Mathura and Agra due to the increase in water pollution. This has also resulted in shortage of drinking water supply to the historic Taj city; one of the most renowned tourist spots in India.
This is the third time that the aquatic life in Yamuna has been faced with such health consequences. In fact the water supplied in Agra during the last week was pale yellow in color and not even fit for drinking. The scenario in and around Delhi is almost the same with huge amounts of sewage from 19 major drains finding its way into the Yamuna. Apart from this the increase in population and the increase in domestic waste have added to this problem. Most small scales industries do not have facilities to treat waste water and dump all their contaminated and waste factory products into the river waters.
The 48km stretch of Yamuna River in Delhi is heavily populated with industrial as well as domestic waste and is unfit even for animal consumption and irrigation. If nothing is done fast the pollution level will only worsen and make matters worse for humans as well as animals and fishes.
