Where Can I Find BPA-Free Water Bottles?

Question: Where Can I Find BPA-Free Water Bottles?

Answer:

While the bulk of the research shows that Plastic #7 (Lexan, Nalgene and other polycarbonate) bottles do not leach BPA in amounts proven to cause health concerns in humans, some governmental advisory bodies such as Health Canada are considering banning them. Water bottle manufacturers swiftly responded by changing their plastic recipe to eliminate BPA, or happily labeling "BPA-Free" the polyethylene plastic and aluminum bottles that never had the chemical.

Does Bisphenol A Leach from Bottles?

Studies subjected plastic BPA-containing bottles to brutal conditions to see whether they would actually leach BPA. The bulk of the research found zero to minimal leaching, far below safety standards. But many people prefer to avoid it altogether. I had several walkers at a walking festival question whether the free bottles the sponsor provided were "safe." The market responded fast to satisfy those customers, even if their fears ultimately are unfounded.

Are There BPA-Free Water Bottles?

Yes. Many water bottles were never made with polycarbonate. And companies such as Nalgene have reformulated their plastic without BPA. Look for prominent labeling of BPA-Free on water bottles as a marketing tool.

Reusable Water Bottles are Better for the Environment

Disposable bottled water bottles and other drink containers are a poor use of the earth's resources, even if recycled. Using a sturdy, refillable water bottle is a great way for walkers to be thrifty and be kind to the earth.
