Yamuna River Turns Pink: A Toxic Warning
16 Mar
Summary
- Pink froth on Yamuna indicates severe chemical pollution from industrial waste.
- Pollution causes health risks and harms aquatic life in Delhi's river.
- Activists demand investigation into dye sources causing the pink tint.
The Yamuna River, downstream of Delhi, has recently exhibited a striking pink froth, an alarming indicator of severe chemical pollution. Activists attribute this phenomenon to untreated industrial waste and toxic effluents being discharged into the river. This chemical foam, laced with dyes and surfactants, poses serious health risks and endangers aquatic life, despite billions invested in clean-up initiatives.
Officials explain that surfactant molecules in polluted water, when agitated at the Okhla barrage and stabilized by lower temperatures, create the visible froth. Sources include detergents, industrial pollutants, and decomposing organic matter. Experts suspect untreated effluents from dyeing or coloring industrial units are responsible for the pink tint, citing similar incidents in March 2023 and 2016.
A study commissioned by the Delhi government in 2025 highlighted the poor performance of sewage and effluent treatment plants, identifying discharge hotspots. The Delhi Jal Board has yet to comment, with one official suggesting the Delhi Pollution Control Committee might identify the cause, possibly a dye or iron-rich pollutant.
