Prof. SenGupta's work with arsenic-tainted water
is detailed in India's Hindustan Times

The Hindustan Times of India published an article in December about the efforts by Arup SenGupta, professor and chair of civil and environmental engineering, to relieve the suffering of people in East India and Bangladesh who are drinking arsenic-contaminated well water.

SenGupta has developed a simple and inexpensive well-head unit that removes arsenic from well water. With help from Bengal Engineering College in India and from Water for People, a Colorado-based nonprofit organization, he has installed the unit in more than 100 village drinking wells near Howrah and Calcutta in India.

An estimated 80 to 100 million people in India and Bangladesh are drinking water containing toxic levels of arsenic. Symptoms can take years to develop and include skin ulcers, tumors, loss of fingers and toes, and cancer.

SenGupta, who grew up in the Indian state of West Bengal, calls the crisis "the biggest natural calamity of our time."
