'Disturbing'
As part of the probe, Face The Facts sent sludge samples to the UK for
examination at the University of Exeter.
Tests revealed the material was useless as a fertiliser and contained a
number of toxic metals, including cadmium and lead.
The lab's senior scientist, David Santillo, said: "What is particularly
disturbing is that the contamination has spread to the water supply - with
levels of lead in a nearby well at levels well above those set by the World
Health Organisation."
According to Britain's leading poisons expert, Professor John Henry,
consultant at St Mary's Hospital in London, immediate steps should be taken
by the authorities in India to ban the practice immediately.
The levels of toxins found in the samples would, he said, cause serious
problems - polluting the land, local water supplies and the food chain.
