To deal with the problem of foam formation on the surface of the Yamuna River near Delhi, when Chhath Puja is around the corner, the Delhi Jal Board (DJB) officials are resorting to spraying the river water surface with chemicals.

Ahead of the Chhath Puja, which is usually celebrated on the river banks in northern India, the DJB officials sprayed chemicals on the surface near Kalindi Kunj, with the aim to remove the toxic foam formed by high level of pollutants in the water.
