The Kerala State Pollution Control Board (PCB) has found that the illegal discharge of pollutants from the Sud-Chemie India Pvt Ltd in the Edayar industrial area has resulted in the discolouration of the Periyar river on September 7.
The change in colour was detected in the river stretch close to the unit. The board officials had taken samples after local residents and activists had alerted them about the discolouration. Tests conducted at the central lab of the board in Ernakulam found the presence of chromium, which indicated that the discharge was from the industrial unit. The illegal discharge was carried out through the stormwater drain meant for release of rainwater, according to the findings by the board.
Notice has been issued to the company management seeking an explanation as to why such an illegal discharge occurred through the stormwater drain. It should also explain the steps taken to prevent such incidents in the future.
