Toxic foam blankets Foreshore Estate beach, public urged to stay away

Activists and biologists have urged the public to stay away from the shores and not to venture into the sea. The frothing usually spikes the curiosity among the public, especially children, and they can be seen playing in it. But it is not advised as the chemicals could harm the skin and even more.

Locals claimed that the recent rain has resulted in an increase in water level in the Adyar river and untreated sewage flowing into the sea. “Frothing is becoming a frequent problem, especially after it rains. When activists visit the place after frothing, they ask us not to come in contact with the foam as it can cause skin infections,” said Sasi Kumar, a resident of Srinivasapuram.

Tamil Nadu Pollution Control Board (TNPCB) officials urged the public to exercise caution and avoid venturing into the beach during frothing. Officials said that they have collected water samples and sent them for chemical analysis. “Frothing happens when large quantities of sewage from Adyar river flows into the sea and the wind foams it. It is unsafe to bathe in the sea during this period.”

“The major reason for frothing is non-biodegradable, detergent-like substances from chemical effluents. The sea has been rough for the last two days due to depression and the stocked-up sediment filled with phosphate in the Adyar river flowed into the sea due to high tides. Frothing will continue for a few days, which indicates high alkaline water. The marine life will suffocate to death due to respiratory problems as the oxygen level is less,” said Joe K Kizhakudan, Scientist, Central Marine Fisheries Research Institute.
