Check your water bottles

kleen kanteenBPA (Bisphenol A) is a chemical compound found in a number of plastics.  The effect of BPA on humans is still disputed by some but the majority of the scientific community seems to embrace BPA as a human health hazard and potential carcinogen.  BPA can leach from the plastic to the contents.  At one point it was a compound in the manufacturing of many water bottles used in the outdoor world.  If you want a plastic water bottle without BPA, check to make sure it’s BPA free.   Additionally, many of the metal (usually aluminum) water bottles have an epoxy resin lining that could contain BPA.  Each reputable water bottle manufacturer will disclose whether or not the bottle or lining contains BPA.   If you can’t easily find the information there’s a chance that your bottle contains BPA.  As a side note, many food cans and other plastic food containing materials contain BPA.
Take anything from wikipedia with a grain of salt as it is user created, but it does have a lot of content on BPA and further references and resources for you to decide for yourself.

Also, if you own a Sigg bottle you can get it replaced here:
