The toxic foam was seen floating around the Vaigai river and Sellur Pond after heavy rains in Tamil Nadu’s Madurai on Saturday.
The foam was a result of mixing of wastewater in ponds and the river with the rain.
Fire department officials were called to spray water along a channel of the Vaigai river, over a bridge in the Sellur area.
Apart from it, Chennai’s Korratur area where rain water entered in shops caused huge loss. Part of Rameswara also experienced waterlogging due to the heavy rainfall in Tamil Nadu.
