Twenty years ago, Smith and colleagues described groundwater arsenic (As) contamination in Bangladesh as the "largest mass poisoning of a population in history." An estimated 60 million people were unknowingly drinking groundwater containing dangerous concentrations of naturally occurring As.

Arsenic mitigation in Bangladesh, though significant, has impacted less than half of the affected population (Ahmed, Ahuja et al. 2006). The most common arsenic mitigation option in Bangladesh at 29% is well switching, which involves switching from an arsenic unsafe well to an arsenic safe drinking water source.
