Delhi govt plans to research microplastics and foaming in the Yamuna

28 Jul 2022 CW Team

The Delhi government will conduct tests to determine the concentration of microplastics in the capital's groundwater and to identify pollution hotspots that cause the Yamuna to foam.

Additionally, a study will be conducted to identify any potential obstacles to the ban on single-use plastics.

The three investigations, which are due to be finished within six months after the project's assignment, will be carried out by reputable institutes chosen by the Environment Department. One of the research will identify the causes and factors for the froth on the river's surface, which indicates that the water is "dead" and has no dissolved oxygen.

High phosphate levels in the wastewater are the main cause of the poisonous foam's development. The main source of phosphates is detergents used in dyeing businesses, dhobi ghats, and homes.

Untapped drains allow phosphate-rich wastewater from authorised colonies and communities to enter the river. The turbulence caused by the water falling from a height at a barrage stirs up the phosphoric compounds in the river, which causes froth to form.
