I know it is confusing but, most bottled water actually comes in PETE (Polyethylene Terephthalate) bottles (marked with the number 1).

On my way out of the house, I grab a couple of liters of filtered tapwater in old nalgenes from the garage fridge, and drop them in a soft side cooler, and toss it in the car. Stored in the car are 5 liters in platypus bags. regarding plasticizer leaching, see Blast's wisdom. There is a lot of noisy bad science out there, cuz advancing a cause is of more newsworthiness than is the truth.

Thanks, Doctor! BTW how's work on the Flubber going?

Whether we're talking phthalates or BPA, so far the concern with human health is primarily restricted to exposure during certain critical times in life, such as infancy, childhood, pregnancy, and maybe adults who are trying to have children since exposure can affect fertility. Otherwise, knock yourself out.

How about unlined stainless steel water bottles?

snopes on bpa in soup cans

Lots of bpa in the world of processed food. It is water soluble so blood levels don't remain high very long, cuz the body excretes it. And nobody has demonstrated that it has any harmful effects. Conclusion: water bottles don't kill people, dehydration does.

BPA isn't a good thing, and nowadays it's very easy to avoid. IIRC all Nalgenes are BPA as are most other brands of water bottles. While I do have one or two plastic bottles I have a dozen stainless steel one. I much prefer the steel ones, if for not other reason than that I can boil in them.
