Toxic white foam was spotted floating on the Yamuna near Delhi’s Kalindi Kunj on Monday, 2 November 2026, and cleaning operations were launched to clear the froth off the river.

Visuals from the area show thick layers of white foam sitting on the river’s surface. The sight has once again put Yamuna pollution back in the spotlight, with officials saying the affected stretch is being cleaned.

Visuals from the area show thick layers of white foam floating on the river’s surface amid recurring concerns over Yamuna pollution.

The foam is not a new problem for the river. The report describes the phenomenon as recurring, and the sight is becoming a familiar one for people who live near the water and for those who track the river’s condition.

The foam forms near the Kalindi Kunj barrage in southeast Delhi. The report says it is particularly common during the winter months, a timing that tends to make the sight more striking because the water is already under scrutiny.

What is causing the foam

The cause, according to the report, is high levels of pollutants entering the river. Detergents and untreated sewage are the two specific inputs named. Put simply, the things people wash with and the waste that does not get treated before reaching the river are what end up building into the froth.

That link matters. Foam is the visible part of a problem that cannot be seen from the riverbank. When a river carries that much detergent and sewage, the surface can turn into a thick white blanket, and the water underneath is carrying the same load.

Why officials are cleaning it up now

Cleaning operations are being carried out in the affected stretch to remove the foam, officials said. The clean-up is a direct response to the froth on the water, but it treats the symptom rather than the source named in the report.

The report does not say how long the clean-up will take, and it does not describe a timeline for stopping the inflow of detergents and untreated sewage. Those are the questions residents and environmental watchers will want answered next.

A warning about water quality

The accumulation of foam has also raised concerns over the deteriorating water quality of the river. That phrase is the most important line in the report. Foam can be photographed and shared in minutes, but the water quality question is slower, harder and far more serious for a river that runs through the capital.

Every time the froth returns, it reignites the same argument. Visible pollution gets attention for a few days, a clean-up begins, and then the next winter brings the foam back. The report frames the foam as part of a broader pattern of pollution that has been building for some time.

The images are hard to ignore. Thick white layers on a river that many people see every day make the pollution feel immediate, not abstract. That is why this story is spreading quickly, and why the questions about the source of the pollution are only going to get louder.

For now, the facts are clear. Toxic foam is floating on the Yamuna near Kalindi Kunj, cleaning crews are working on the affected stretch, and the foam is linked to detergents and untreated sewage entering the river. What comes next depends on whether the inputs behind the foam are addressed, and the report does not say that has happened yet.
