Any liquid in your water bottle can be contaminated by the metal or plastic vessel in which it is stored. And, if that bottle or container is heated from sitting in the sun in hot car or in the microwave, more toxins can be released from the plastic or metal. That's why it is so important to take care with the material that your water bottle is made from and how you clean and care for it.
Read more about BPA below, but in a snapshot, avoid polycarbonate #7 and polyvinyl chloride (PVC) #3 plastics, especially for children’s food. Plastics with the recycling labels #1, #2 and #4 on the bottom are safer choices and do not contain BPA.
At Biome, the BPA free water bottles we stock are not only BPA free but also do not contain any lead or phthalates.There are many cheap metal water bottles in stores to meet the consumer demand for moving away from plastics. We recommend only choosing an established drink bottle brand that you know and trust, that openly publishes independent test results, and that can be held accountable should there be a problem. You and your family are the ones who drink from the bottles and need to feel comfortable with whichever choice you make.

Bisphenol A (BPA) is a plastic and resin ingredient used to line metal food and drink cans and to make hard and clear polycarbonate plastics. Here is a summary of the Environmental Working Group study <http://www.ewg.org/reports/bisphenola> in 2007 which found BPA in over half of 97 cans of name-brand fruit, vegetables, soda, and other commonly eaten canned goods.
The use of BPA is widespread, as is its permeation into the environment around us including drinking water and human breast milk. BPA can leach into food from the protective internal lining of canned foods and from consumer products such as baby bottles and water bottles, polycarbonate tableware and food storage containers. The degree to which BPA leaches from polycarbonate bottles into liquid may depend more on the temperature of the liquid or bottle, than the age of the container.

This Z recommends <http://www.zrecommends.com/detail/when-it-comes-to-bpa-free-consumers-have-nothing-to-fear-but-fear-itself/> article explains the great advances made away from unsafe polycarbonate bottles that contained high levels of BPA, but calls for putting BPA-free into perspective. Canada was the first country to ban BPA from baby products, followed by several US States.
