Are Reusing Store Bought Water Bottles Safe? Maybe Not

For the longest time, I've been (on occasion) refilling water bottles and putting them in the 'fridge.  Why not, right?  It's just water.  Well, the jury is out as to whether this is healthy or not (like everything else in the world).

Looks innocent enough for me.  Just rinse it out and refill it.  What's the problem?  Well, I guess it could be a virtual petrie dish of germs.

According to AskAlice.com, there are two camps:  the refiners and the non-refillers. Refillers say that if you use hot soapy water, you can get a few more refills out of them.   The non-refiller defense, according to the article states

"...only bottles specifically made to be reused should be refilled. For starters, they say that all kinds of bacteria can thrive in made-to-be-disposed bottles, even after washing

You can read the whole article. I'm interested in knowing if you say "damn the torpedoes" and refill them yourself, or do you play it safe?  Between you and me - how dirty and unsafe can they possibly be?  I'll bet you the bottles have bacteria on them right out of the package.   What say you?  Please leave your comments at the bottom.  And remember -drink 8 glasses of water a day!
