Action initiated against local bodies and industrial units
The State Pollution Control Board has initiated action against local bodies and industrial units found polluting the Periyar River, based on the water quality levels at select monitoring stations.

The Ernakulam Regional Office of the board has asked the Kalamassery Municipality to clean up the Thoombunkal thodu based on the finding that industrial discharge and indiscriminate waste disposal had led to the depletion of oxygen levels at Puthalamkadavu,
