Most Polluted River in India
The Yamuna River is often considered one of the most polluted rivers in India. It faces severe pollution issues, particularly in the stretch passing through Delhi, where it is heavily contaminated with untreated sewage and industrial waste.
Key Facts About Yamuna River Pollution:
Pollution Sources: This river receives over 50% of Delhi's waste, including untreated sewage and industrial effluents. High phosphate content from detergents used in industries and households contributes to toxic foam formation
Impact on Health and Environment: The water quality is classified as E-class, making it unfit even for animal bathing. The pollution poses significant health risks to millions of people dependent on the river.
Government Initiatives: The "Yamuna Action Plan" aims to clean the river, but progress has been slow, and pollution levels remain high.
The Yamuna River, one of India's most sacred rivers, faces severe pollution challenges due to various human activities. Here are the key reasons why it is considered one of the most polluted rivers:
Main Sources of Pollution:
1. Untreated Sewage:
⦿ Domestic Waste: Over 800 million liters of largely untreated sewage are discharged into the Yamuna daily, primarily from urban areas like Delhi. This accounts for about two-thirds of the river's pollution.
⦿ Insufficient Treatment: Only about 35% of the sewage is treated before being released into the river.
2. Industrial Effuents:
⦿ Toxic Chemicals: Industrial zones along the river, such as those in Yamunanagar, Panipat, and Ghaziabad, release heavy metals and hazardous materials into the water.
⦿ Industrial Waste: This includes chemicals from oil refineries, distilleries, pharmaceuticals, and other manufacturing units.
3. Agricultural Runoff:
⦿ Pesticides and Fertilizers: The use of chemical fertilizers and pesticides in agriculture contributes to pollution, affecting aquatic life by reducing oxygen levels in the water.
4. Solid Waste and Cultural Practices:
⦿ Direct Dumping: Inadequate waste management leads to the dumping of solid waste directly into the river.
⦿ Cultural Practices: Immersion of idols and ceremonial materials during religious events also contribute to pollution.
Impact of Pollution:
• Health Risks: The presence of heavy metals and pathogens poses severe health risks, including respiratory issues, kidney damage, and neurological disorders.
• Environmental Damage: The pollution disrupts the local ecosystem, reducing biodiversity and affecting aquatic life.
The Yamuna River's pollution is a complex issue involving untreated sewage, industrial waste, agricultural runoff, and cultural practices. Addressing these challenges requires collective efforts from government agencies, environmental organizations, and public participation to restore the river's health.
