Well Water Arsenic Mitigation in Bangladesh: Benefits Outweighing Risks of Sharing Private Environmental Data.

ABSTRACT: This paper argues that environmental data should be collected and shared more widely to benefit public health while maintaining privacy, using Bangladesh's well water arsenic crisis as a case study. Arsenic of natural origin in well water causes about 5% of adult deaths in Bangladesh, but a recent study shows that mortality returns to background levels within a decade after exposure ends. This finding motivates comparing the Bangladesh government's testing of millions of wells for arsenic in 2000-2005 and again in 2021-2023. Despite progress, the data reveal that 20 million Bangladeshis still consume unsafe water today, largely due to a lack of information and suboptimal interventions. We propose reviving arsenic mitigation through public sharing of anonymized test data via a web applicati
