ETPs at Ankleshwar, Vapi don’t meet GPCB norms, DNA, Ahmedabad, 23 May 2012
DNA, Ahmedabad, 23 May 2012
Ahmedabad: Close on the heels of Vapi topping the list of most polluted industrial sites in the country, here comes another shocker. The Common Effluent Treatment Plant (CETP) at Vapi has failed to meet the norms prescribed by the Gujarat Pollution Control Board (GPCB). The same is the case with the Final Effluent Treatment Plant (FETP) at Ankleshwar, states a report by the Central Pollution Control Board (CPCB).
A report dated February 2012 states that the effluent discharge from the outlet of CETP Vapi has a COD (chemical oxygen demand) of 467. The GPCB norm states that it should be 250 mg/litre.
If that wasn’t enough, the TDS (total dissolved solids) from the outlet is 8,078 mg/litre, which is 384% more than the GPCB norms of 2,100 mg/ litre.
According to the April 2012 CPCB report for Ankleshwar, the effluent discharge from the outlet of the FETP shows a COD of 452, which is 180% more than the GPCB norm of 250 mg/litre. The TDS level was 7,034, 335% more than the acceptable norms set by the state pollution control board.
It should be noted that an interim Comprehensive Environmental Pollution Index (CEPI) report of 2011 had earlier placed Vapi as the most polluted industrial cluster in the country.
Vapi had scored a CEPI of 90.75 while Ankleshwar had scored a CEPI of 85.75 in the 2011 report.
On the effluent treatment plants failing to meet the GPCB norms, Rohit Prajapati of Paryavaran Suraksha Samiti said that the effluent treatment plants in the state are not up to the mark. “The FETP of Ankleshwar even finds a mention as a picture in the book written by the chief minister on climate change. And the same plant can’t even
fulfil the GPCB norms,” said Prajapati.
It should be noted that earlier member secretary of GPCB Hardik Shah had said that the Centre’s norm was 500 mg per litre of COD. Prajapati rubbished the claim stating, “It was reduced to 250 mg/litre a long time ago.”
