It's been 30 years since the Bhopal gas disaster which killed over 5000 people, families of the victims say the legacy of the gas leak lives on today.
Survivors of the world's worst industrial disaster are commemorating 30 years since a cloud of deadly gas leaked from a Union Carbide pesticide plant and engulfed the central Indian city of Bhopal.
But after three decades, activists say it's toxic legacy lives on.
Human rights activist Sathinath Sarangi said thousands of tonnes of hazardous waste remains buried underground, slowly poisoning the drinking water.
"There are 17 studies, both government and non-government agencies have shown that up to three kilometres or three-and-half kilometres from the factory and at depth greater than 20 metres there are chemicals that cause all these damages, cause cancer, cause birth defects," Mr Sarangi said.
There are chemicals chlorobenzene, dychlorobenzene, benzene hexachloride, hexachlorocylohexane, nickel, chromium, mercury in very very high amounts, and yet nothing has been done."
Activists want the waste removed and disposed of away from the area.
They say Indian authorities who now own the site have fumbled on taking action.
Built in 1969 the Union Carbide plant was seen as a symbol of a new industrialized India.
But in 1984, 40 tonnes of toxic gas was released and carried by the wind to the surrounding densely populated area.
The government recorded 5295 deaths.
Activists claim 25,000 people died in the aftermath and following years.
