After a crisis, how can we tell if water is safe to drink? Current tests are slow and complex, and the delay can be deadly, as in the cholera outbreak after Haiti's earthquake in 2010. TED Fellow Sonaar Luthra previews his design for a simple tool that quickly tests water for safety -- the Water Canary.
