PERIYAR TURNS DUMPING YARD FOR EFFLUENTS
About 2.48 crore litres of effluents generated by nearly
55 industrial units in Eloor and Edayar are let out into the Periyar River
daily after primary treatment, against the prescribed norm of ‘zero discharge’
by industries to prevent pollution of rivers.According to the official data
available with the Kerala State Pollution Control Board, there are 270
industrial units in the Eloor and Edayar region.Only 42 industries have
attained the zero discharge status. The board has no information on the
effluents generated by 12 units.Out of the total 270, 98 units fall under the
‘red’ category (highly polluting), 109 in ‘orange’ category (moderately polluting), and 63 came under the ‘green’ category (least polluting).
Industries figuring at the top of the list of units
generating effluents in the region include FACT Ltd. (Petrochemical division –
5,040 kilo litres per day; Udyogmandal division – 4,800 kilo litres per day);
Excel Enterprises, Edayar (5, 040 kilo litres per day); Excel Industries (4,800
kilo litres per day); Hindustan Insecticides Ltd. (1,024 kilo litres per day);
General Chemicals and Polymers (1,024 kilo litres per day); and Binani Zinc
(1,000 kilo litres per day in monsoon and 550 kilo litres during dry season).Board
sources admitted that they lack information on the various types of chemical
effluents generated by the industries in Eloor and Edayar.The State Pollution
Control Board also remains clueless as to the exact source of illegal dumping
of industrial chemical effluents into the Periyar river at different points.A
survey conducted by the Environmental Hydrology Group at the Hyderabad-based
National Geophysical Research Institute (NGRI) in June 2007 had found nearly 60
‘clandestine’ pipelines discharging effluents into the Periyar. Four storage
tanks were found under water by the institute team.Studies also found several
openings into the Periyar in the form of drainage, pipelines and storage tanks.
