It’s hot, so you reach for your sports bottle and encourage the kids to hydrate, too. But to ensure no one’s gulping toxic chemicals with their water, check that the bottles aren’t polycarbonate (PC) plastic, which can release Bisphenol-A (BPA). This spring, the U.S. National Toxicology Program warned that BPA may pose a threat to human health. Animal studies have connected BPA with behavioral and reproductive problems and diabetes, and in lab tests it has caused normal human cells to express genes linked to breast cancer. BPA is already present in 93% of Americans, according to the U.S. Centers for Disease Control’s “body burden” studies of representative populations.
BPA has been found to migrate more readily out of polycarbonate when the plastic is heated, washed in strong detergents, scratched or worn-out. All sports or baby bottles are subject to these conditions, but, happily, not all are made of PC.
Nalgene has announced it will phase out its clear, colorful PC Lexan bottles, and Wal-mart has removed PC baby bottles from its Canada stores and will stop selling them in the U.S. next year.
Meanwhile, here’s a list of BPA-free bottles to look for right now. The newest plastic in sports bottles is Tritan copolyester, which has the clarity and colors of Lexan without the BPA.
Note: Stay on guard regarding polycarbonate (PC) bottles, which remain on store shelves and Nalgene’s website alongside non-PC models. Greenerpenny's top pick is lightweight, unlined stainless steel, the most recycled metal. Next come the recyclable plastics polyethylene (PET, #1), high-density polyethylene (HDPE #2), low density polyethylene (LDPE, #4) and polypropylene (PP, #5). Where noted, the bottles below come in 12 oz (handy for kids) as well as larger sizes.

You forgot one - the BPA free Titan water bottle created by Jared Joyce in Bozeman, MT. It's specially designed for outdoor activities.
It's got a built in carabiner clip, a form-fitting mouthpiece, and features single-handed operation.
Check it out at www.titanwaterbottle.com.
Great post. There's more info on the topic at Bottles Without BPA
Now if you could just put some growth hormone in those bottles you'd really have something!

Nice review. You left out my favorite chemical free sports bottle, the thinksport, which is made by the same company as the thinkbaby bottles you mentioned. Here's a good explanation of the thinksport's features: http://momguru.com/content/thinksport-bottle
