Battling ‘the Largest Mass Poisoning in History’

By Kevin Krajick and David Funkhouser

International health experts have called it the largest mass poisoning in history, and it is still underway. Some 100 million people in southeast Asia have been drinking from shallow wells originally drilled to provide germ-free water; but many turned out to be contaminated with naturally occurring arsenic.

Despite efforts to understand the natural processes at work, and provide safer water, many are still being poisoned, due to scant resources, poor information at local levels, and the sheer numbers of people and wells involved. The result: a slow-burning epidemic of heart disease, cancers, lung problems and compromised child development.

Researchers at Columbia University’s Lamont-Doherty Earth Observatory and the Mailman School of Public Health have been on the front lines of the issue since 2000. They are currently leading a wide range of initiatives, including long-term health programs, continued drilling of safer wells, education and continuing investigations into the geology of arsenic contamination.
