Santosh, Foreign Expert at the China University of Geosciences, Beijing; and K.V. Sarath, Pranav Prakash, V. Deepchand and B. V. Divya of the Department of Geology, University of Kerala.

Arsenic contamination in groundwater was first reported from Chandigarh, and a second case was reported in the lower Gangetic plain of West Bengal.

“’But now we find that 20 States are affected,” Dr. Shaji said.

Drinking arsenic contaminated groundwater can lead to serious health issues including cancers, coronary heart disease, liver damage, arsenicosis and hyperkeratosis. according to the authors.

“’Thirty-three Asian countries are significantly affected by groundwater arsenic contamination. The most affected countries are China, Bangladesh, India, and Pakistan. In India, it is reported that a population over 50 million is currently at risk from arsenic contamination,”’ it noted.
