This is interesting because I know that The Citadel University issues all of it's students these bottles and they are required to have them at all times with water in them.
ROCHESTER, N.Y. (AP) -- Catching his breath at a fitness club, Matt McHugh took a gulp of water from his trusty, hard-plastic Nalgene bottle and pondered the idea of switching to an alternative made of glass, stainless steel or another kind of plastic.
Worries about a hormone-mimicking chemical used in the trendy sports accessory led a major Canadian retailer to remove Nalgene and other polycarbonate plastic containers from store shelves in early December.
"It's definitely a concern but I'd like to learn more before I make any decisions about my water bottles," McHugh, 26, a business manager for a reggae band, said with an easy laugh. "For now, I'll probably keep using my Nalgene until it breaks. It's indestructible, I've heard!"
Vancouver-based Mountain Equipment Co-op is waiting for Canadian health regulators to finish a preliminary review in May before it reconsiders restocking its 11 stores with the reusable, transparent bottles made with bisphenol A, or BPA, a compound created by a Russian chemist in 1891.
