HERE is a disturbing article about pharmacuetical drugs being found in public water all over the united states. Its downright disgusting and SCARY. Yuck. (seriously, read it)
Everyone should have a Brita or Pur filter on their drinking water at home and better yet, a reverse osmosis filter (we got one a few years ago and love it!!!).
Obviously dont drink out of public water fountains or from the tap if you can help it!
Dont buy bottled water - the water isnt healthy and its a waste of plastic. Buy yourself one Klean Kanteen and fill it up at home with your healthy, filtered water! :)
