TOPSHOT - (FILES) In this photograph taken on March 19, 2015, a Bangladeshi woman collects contaminated water to be used on produce at a vegetable market from the polluted Buriganga in Dhaka. - Twenty million poor Bangladeshis are still drinking water contaminated with arsenic, two decades after the potentially deadly toxin was discovered in the supply, Human Rights Watch said April 6. A new report from the rights group said Bangladesh had failed to take the basic steps needed to tackle the problem, which kills an estimated 43,000 Bangladeshis every year, mostly in poor rural areas.
