Unfortunately, no matter what water bottle you use there is going to be some risk of contamination of the contents: bisphenol or some other plasticizer from any plastic bottle, nickel and other metals from stainless steel, aluminum from uncoated aluminum, titanium from titanium bottles and cookware, various contaminants from other linings, etc. There ain't no free lunch. Remember too that the lab tests indicated no leaching into Sigg's bottles with the old liners with water sitting in there far longer than a bicyclist is likely to leave it- but the presence of bisphenol in any quantity, coupled with Sigg not mentioning it, was enough to set off a firestorm that may yet destroy the company.
And what do you put into your water bottle? Bottled water? Same problems as your water bottles. Tap water? Our local tap water has been found to contain 27 quantifiable pharmaceuticals plus various naturally occurring contaminants plus 3M contaminants leaching from landfills plus other industrial contaminants plus agricultural contaminants. Filtered water? Doesn't get all of those things out plus adds the risk of bacteria living in the filters. Well water? Most non-public supply wells are rarely tested so you have no idea what's in there. Life's a crapshoot is what I'm saying. If you live, breathe, eat or drink water on planet Earth you're going to be exposed to more chemical contaminants and pollutants than you can count. We've been taking a dump in our living rooms for a very long time and there are a lot of vested interests to prevent any changes in the policies that allow this (riding a bike instead of driving at least helps a little bit with this and, if we all took Copenhagen's example, could help a whole lot). My guess is that having water in just about any water bottle for an hour or two is unlikely to leach enough stuff into the water to hurt you, even if you did it every day for the next 20 years. You probably shouldn't keep it in there for weeks and then drink it.
