My wife (an RN) and I sat around and did an evening's worth of research on the subject of water bottles and here's what we came up with:
- single-use: Bad environmentally. Don't re-use, or they might be bad health-wise.
- Polyethylene multi-use: Fine.
- Polycarbonate (Nalgene & imitations): Could be bad for you.
- Aluminum: Most aluminum bottles are-- guess what? Coated with epoxy on the inside, so they're technically plastic. Couldn't get the health implications of the epoxy involved, though.
