Delhi's Toxic Trouble: Froth Covers Yamuna River Ahead Of Chhath Puja-What's The Reason Behind It
Delhi grapples with severe air and water pollution, particularly evident in the frothing of the Yamuna River during October and November. This frothing, driven by untreated sewage and industrial effluents, poses significant health hazards to the population.

KEY HIGHLIGHTS
- Froth formation occurs due to the decomposition of organic matter and is facilitated by pollutants like phosphates and surfactants.
- Major sources of pollution include untreated sewage, industrial effluents, and organic debris.
- Short-term exposure can cause skin issues, while long-term exposure to heavy metals can lead to serious health problems.
New Delhi: During October and November, Delhi faces a significant dual challenge of air and water pollution, with the frothing of the Yamuna River becoming a prominent concern. Already heavily polluted, the river experiences heightened levels of contamination during the post-monsoon months and the beginning of winter, resulting in the notorious froth.
What is Froth Formation?
Froth formation is a phenomenon observed in various lakes and streams, where foam bubbles are generated as organic matter decomposes. These foam-producing molecules possess a structure that allows one end to repel water while the other attracts it, effectively reducing the water's surface tension. Because these foam bubbles are lighter than water, they float to the surface, creating a thin film that gradually accumulates over time.
Causes of Froth Formation
Experts identify untreated sewage from Delhi, Haryana, and Uttar Pradesh as a primary contributor to frothing in the river, primarily due to the presence of phosphates and surfactants. Although these two components account for only 1 per cent of the mixture, the remaining 99 per cent consists of air and water, which together facilitate the frothing process.
Sources of Pollution Leading to Foam Formation
Foam formation is primarily driven by several sources of pollution, including untreated sewage that often contains soap and detergent particles. Additional contributors include industrial effluents, organic matter from decomposing vegetation, and the presence of filamentous bacteria.
Notably, pollution from the sugar and paper industries in Uttar Pradesh, which flows through the Hindon Canal, also significantly impacts the Yamuna River's water quality.
Health Hazards
Short-term exposure to polluted water can result in skin irritation and allergic reactions. Ingesting these chemicals may lead to gastrointestinal issues and illnesses such as typhoid. Additionally, prolonged exposure to heavy metals found in industrial pollutants can cause neurological disorders and hormonal imbalances.
