A 20-year study in Bangladesh has found that reducing arsenic levels in drinking water was associated with as much as a 50 percent reduction in deaths from heart disease, cancer and other major chronic illnesses. Researchers followed nearly 11,000 adults and reported that participants who switched to safer wells eventually had mortality risks similar to people who were never heavily exposed to arsenic. The findings, published in JAMA, underscore the global health benefits of tackling arsenic contamination in drinking water.
