We know disposable drinking water bottles are bad news. And we also know that drinking bottled water isn't necessarily better than drinking tap water. So instead of heading to the corner store to pick up some water, grab this free Android app and locate the nearest drinking water fountain (and help crowdsource the data by adding to it)!

It used to be fairly common to find drinking fountains in most public places, but the sad fact is, they seem to be disappearing. But a new initiative from Pacific Institute could start to change that trend. Their new WeTap app uses the world's largest crowd-sourced database of drinking water sources, to map new ones, and to report any broken fountains so they can be fixed and put into service.
