Protesters, led by five NGOs working for survivors of the tragedy, in which leakage of poisonous MIC (methyl isocyanate) gas from Union Carbide factory killed thousands of people on the night of December 2-3, 1984, held banners at the site where hazardous waste in thousands of tons is buried 400 metres north of the factory for the last 19 years.
"It is Union Carbide that buried the waste next to our homes. Why is the Indian government not able to make Union Carbide's current owner Dow Chemical accept legal liability and clean up the toxic waste?" 'Bhopal Gas Peedit Mahila Stationery Karmchari Sangh' president, Rashida Bee said.
Satinath Sarangi of Bhopal Group for Information and Action said that a legal petition for removal of the hazardous waste and clean up by Dow Chemical was pending before the Madhya Pradesh High Court for last 11 years.
According to the organisations, the hazardous waste from the pesticide factory was buried in 1996 by the factory management. The waste is known to contain chemicals that cause cancers and birth defects and damage the liver, kidneys, lungs and the brain.
Further tests have shown that the contamination has spread beyond 22 communities and it will continue unless the buried waste is removed from the site, they added.
