According to a joint World Health Organization/UNICEF report issued this week, an estimated 768 million people relied on unimproved drinking-water sources in 2011, with 185 million of these relying on surface water to meet their daily drinking-water needs. WHO and UNICEF have set a 2030 target for everyone to have access to a safe drinking-water supply and new water-purifying “nanoscavengers” developed by researchers at Stanford University could help achieve this goal.
