Pink Froth on Yamuna River Raises Pollution Concerns Near Delhi

The Yamuna River near Delhi has recently exhibited pink froth, attributed to chemical pollution from untreated industrial effluents, particularly from textile and dyeing units in Delhi and neighboring Haryana regions. Activists, including Pankaj Kumar of Earth Warrior, highlight the presence of dyes, surfactants, and other pollutants causing health and ecological risks. The National Green Tribunal has previously ordered closure of unauthorized dyeing units, but concerns persist over enforcement and ongoing pollution. Experts explain the froth forms due to surfactants in polluted water agitated at the Okhla barrage, with colder temperatures stabilizing the foam.
