Bisphenol A (BPA) is a dirty word these days. Found in items such as polycarbonate plastics (e.g., certain Nalgene bottles), some plastic baby bottles and the lining of canned goods, BPA is linked to a host of ailments in animal studies. The National Toxicology Program is officially concerned, Canadian retailers are taking BPA-containing products off the shelves, Canada just banned BPA from baby bottles and Nalgene has succumbed to market pressure to remove BPA from their hydration offerings.

I've tossed every polycarbonate plastic bottle our family ever owned into recycling. We recently purchased a couple of BPA-free water bottles and are looking to expand our hydration repertoire with two or three more. If you're seeking BPA-free hydration, consider these:

CamelBak: We now own two BPA-free Camelbak Better Bottles and love their sleek and slim design, 24 oz capacity and easy-off lid. At $9.00 a piece, they were affordable. Check out their flip cap Better Bottle which features that famous bite/sip valve. Eastman Tritan copolyester plastic is the magical material here -- it's BPA-free.

SIGG: With 144 designs and 22 interchangeable lids, these aluminum water bottles have style. The interior lining is non-leaching, resists residue build-up and retains good taste. Cute kid bottles, too. Prices vary. Check out my earlier post on SIGGs.

Enviro New Wave: Stainless steel bottles available in a variety of sizes. Their 12 ouncer is a nice fit for kids. It might be harder to find a retail source, however the website offers a store locator.

Klean Kanteen: Available in 12, 18, 27 and 40 oz sizes, this stainless-steel wonder is non-leaching, toxic-free and not lined with any material. A wide mouth swallows an ice cube and it's dishwasher safe. Prices vary.

Nalgene: A new player in the Tritan/copolyester market, their Everyday bottle line offers a variety of durable, colorful choices. I've always loved the look of a Nalgene and their Everyday line delivers. The OTG Tritan/22 oz costs around $10.00.
