Toxic foam has resurfaced on the Yamuna near the Kalindi Kunj barrage in southeast Delhi, prompting cleaning operations on the affected stretch as concerns over the river’s deteriorating water quality return to the public spotlight.
The white froth was seen floating on the river on Monday, with visuals showing thick layers covering parts of the water surface. Officials said cleaning work was underway to remove the accumulated foam from the affected area.
The incident has again brought attention to the recurring appearance of foam along the Yamuna, particularly near the Kalindi Kunj barrage during the winter months. The formation is associated with high levels of pollutants in the river, including detergents and untreated sewage entering the water system.
The latest episode is not an isolated visual problem. The foam is a visible sign of pollution entering the river and accumulating in a stretch where water quality has remained a recurring concern. Its return also highlights the operational challenge faced by authorities: removing foam from the surface can clear the immediate obstruction, but the underlying pollutants continue to enter the river unless the sources are addressed.
The affected location near the Kalindi Kunj barrage has previously emerged as one of the most recognisable sites for Yamuna pollution in Delhi because the foam becomes concentrated and highly visible on the water surface. The accumulation is particularly noticeable during winter, when the river’s condition again becomes a prominent public and administrative concern.
Officials were carrying out cleaning operations when the foam was reported on Monday. The supplied report does not specify the equipment being used, the volume of foam removed, the duration of the operation or whether additional measures have been announced to prevent further accumulation.
The immediate response is focused on clearing the white froth from the affected stretch. However, the reported causes point to a wider urban infrastructure and governance issue involving wastewater treatment, sewage interception and the control of detergent and other pollutants entering the Yamuna. The incident therefore links a visible river condition at Kalindi Kunj to the performance of systems operating upstream and along the river’s urban corridor.
The current report does not provide fresh water-quality measurements or identify a specific discharge point responsible for this episode. It also does not state whether the cleaning operation is part of a scheduled programme or a short-term response to the resurfacing. Further details from the authorities on the operation and the steps being taken to control pollutant inflows remain awaited.
