New Delhi, March 18 The foam on the Yamuna River in the Kalindi Kunj-Okhala barrage area is largely due to the structural and flow conditions at the barrage, Delhi's Water Minister Parvesh Sahib Singh Verma said on Wednesday.
Accompanied by experts, the minister conducted an inspection at Kalindi Kunj and nearby Yamuna ghat areas following the appearance of foam in a specific stretch of the river.
"What we are seeing here is a localized phenomenon. The foam formation in this stretch is linked to specific technical conditions at the barrage. At the same time, our efforts to reduce pollution in the Yamuna are ongoing and continuous," he said.
Due to the slope at the barrage, water falls with force, creating turbulence. This agitation causes existing impurities in the water to turn into visible foam, which is primarily seen in this particular stretch, he added.
"During the visit, experts highlighted that the foam formation is localized and largely linked to the structural and flow conditions at the Okhla barrage," the minister said.
Officials further explained that, in addition to turbulence at the barrage, the presence of surfactants, largely from household detergents, also contributes to the formation of foam, a statement said.
In addition, discharge from illegal dyeing units, waste from laundry clusters and dhobi ghats, as well as inflows from certain drains carrying untreated or partially treated wastewater, also add to the overall load, it added.
