Local environmentalists blame an international oil consortium now drilling its first well in the shallow waters of Kazakhstan's sector of the Caspian Sea.
Lord Hoffman, in the ruling on the case, said the tests had no relation to the shallowwell serving Mr Sutradhar's village, and it was not the practice at the time to test for arsenic.
The Texas Railroad Commission, using chemical fingerprinting, maintains that the EPA is wrong and that the gas seeped into the well from a shallow formation a few hundred feet beneath the surface, much closer to the water wells.
