You thought this topic was dead. My wife was at the Nalgene website and saw that they were discontinueing production of bottles that have BisphenolA (BPA) in them. There is still not much scientific information to prove that there is a problem, but customers are not buying them anyway. They are using different materials that do not contain BPA. Also, on CNBC, they interviewed the head of Eastman Chemical and he said they are producing baby bottles without BPA now. I don't know if ACO has any solutions or not.
Q. Are polycarbonate bottles safe? A: Yes. Agencies and researchers worldwide have studied the safety of BPA and polycarbonate for approximately 50 years; including The Environmental Protection Agency and The Food and Drug Administration in the USA, The European Commission Scientific Committee on Food, The German Federal Institute for Risk Assessment and the Japan Ministry of Health, Labor and Welfare. Findings of studies from these agencies indicate that food and beverage containers manufactured from polycarbonate do not pose a health risk to humans. As a result, polycarbonate is used in a wide variety of consumer products including baby bottles, water bottles, dental sealants and the lining of most food & beverage containers.
Furthermore, several scientific panels including the European Union's Scientific Committee on Food, the National Toxicology Program and the Harvard Center for Risk Analysis have concluded that the weight of scientific evidence does not support the hypothesis that low doses of BPA adversely affects human health. None of the large studies conducted have substantiated the claims made by those performing some of the smaller studies frequently cited.
Interesting. For years, we used the opaque white polyethylene Nalgene bottles for camping and hiking, but they left a definite odor in the water. We switched to the nearly clear polycarbonate Nalgene bottles years ago thinking that the lack of odor meant cleaner water. Not sure how practical it will be to carry glass bottles. Maybe stainless until ACO takes over the market.
