Alarming foam in Yamuna river raises health concerns amid festivities

On Friday, the Yamuna River in Delhi was seen covered with a thick layer of white froth, alarming health experts as the festive season approaches. Videos circulating on social media showed vast sections of the river resembling clouds over the water, which gradually dissipated later in the day. Bhim Singh Rawat, Associate Coordinator of the South Asia Network on Dams, Rivers & People (SANDRP), remarked on the unusual conditions, stating, “Normally, the upper segment of the Yamuna experiences significant flood spells, but this year, there have been none during the just-concluded southwest monsoon of 2024." He noted that this absence is concerning, as the river typically experiences at least a couple of low or medium flood spells each year.

Rawat emphasized that the pollution in the river is a serious issue impacting both human health and local wildlife. While the Yamuna has some natural cleansing capabilities, the pollution levels remain alarming. He pointed out that the visible white froth, which has been prevalent during this year's monsoon, tends to become more noticeable around festival times.

Environmental experts have urged the government to take action regarding the pollution levels in the Yamuna, particularly with significant festivals like Chhath Puja approaching. They warned that the frothy foam contains high levels of ammonia and phosphates, which pose serious health risks, including respiratory issues and skin problems. An expert explained, “This kind of foam formation is common when fats from decaying plants and pollutants mix with the water, but its presence during the monsoon is surprising.” The frothing phenomenon has been attributed to the lack of flood spells that usually help wash away accumulated pollutants.
