As many as 27 US lawmakers have asked Dow Chemical Company, which now owns Union Carbide, to immediately take steps towards providing medical and economic rehabilitation to victims of Bhopal gas tragedy.

"We request that Dow ensures that a representative appear in the ongoing legal cases in India regarding Bhopal, that Dow meets the demands of the survivors for medical and economic rehabilitation, and cleans up the soil and groundwater contamination in and around the factory site," the lawmakers said in a letter to Andrew Liveris, the Dow Chairman and CEO.
