The sustainability of arsenic-safe groundwater in the Bengal Delta

Worldwide, an estimated 220 million people are drinking groundwater containing the toxin arsenic (As) at concentrations above the World Health Organization guideline of 10 parts per billion. About 94% of the people at risk are in Asia. Chronic As exposure through drinking water can lead to cardiovascular disease, cancers and skin lesions in adults, and diminished intellectual and motor function in children. In many As-affected regions, reliance on low-As (safe) aquifers is the most promising way of reducing exposure. Understanding the sustainability of long-term pumping from these safe aquifers motivated this research. Read more...
