As a postscript to previous posts about the health risks from Nalgene bottles, check out this article on cnn.com.

The article is consistent with what we discovered; there is evidence of risk from exposure to bisphenol A (or BPA) in polycarbonate, but no hard evidence linking such risks to use of Nalgene bottles or similar products.

The recent actions of Mountain Equipment Co-op, the respected, environmentally-friendly outdoor supplier from Canada, simply adds to the confusion: they removed polycarbonate water bottles from their product line, but continue to carry water filters and other products containing the polycarbonate.

At present, the best advice appears to be replace Nalgene bottles about once a year, and more often if you routinely use them for hot liquids.
