The tanneries in Ambur and Vaniyambadi regions have been given a deadline up to this month end to complete the installation of the reverse osmosis system for treating effluents through individual and common treatment plants. This was disclosed by district environment engineers attached to the Tamil Nadu Pollution Control Board (TNPCB) at the monthly grievance meet for farmers here that was chaired by district collector Rajendran on March 21, 2010. This they said in response to a volley of queries raised by a group of farmers in connection with the pollution control measures initiated by the TNPCB. The farmers pointed out that the polluted water had destroyed the crop in many pockets and demanded adequate compensation from the industry for the crop loss, damage of the land, damage on the health conditions of farm animals and human beings. The group also pointed out that at least five to six persons died every year due to this hazardous industry and wanted to know what action was taken by the PCB. The farmers insisted that the industry be made to reuse its effluent thus ensuring zero discharge and safety for environment.
