ABSTRACT
Chronic exposure to arsenic from drinking well-water in Bangladesh has taken an immense toll. After an initial campaign to blanket test all wells in the country, mitigation efforts have faltered over the past decade. The government's new resolve to address the As problem is a unique opportunity for impactful mitigation by combining smartphone technology with the approaches that have been most effective in the past: blanket testing and using this information for the targeting of low As aquifers for private and truly public well installations.
