"Really? Lloyd Alter, after 4 postings and an ambush of comments still comes to the conclusion that SIGGs are safe? Is he for real?"She makes some very good points, including asking why we should believe anything that SIGG says. She may well be right and you should read her post.
But we are swimming in BPA; the industry makes two million tons of it per year. If you eat food from cans, you are getting it. If you feed your kid organic baby food in glass bottles, they are getting it. If you tell me that you drink your water from glass mason jars to avoid it, you are getting it. Until the stuff is completely banned, (which it should be from any food related use) it is not useful to say that a bottle that that tests at zero should be thrown out. I will never buy a SIGG, because I do not think that they have been transparent. But if I owned one I wouldn't spend thirty more bucks to replace it and I have no logical basis to advise others to throw good money after bad.
But if I were looking for a new bottle, here are a few choices where the manufacturers tell us their bottles do not contain any material that every had a hint of BPA in it:
BPA Free Plastic Bottles
Camelbak just nailed the timing when it released its BPA free bottles made with the new Kodak Tritan polyester that looks and feels like conventional polycarbonates but is BPA free. Some are still worried that plastic is scary and who knows what will leach out of this, but the problem with BPA was the unreacted stuff, and the resemblance of BPA to estrogen. Tritan is a whole different chemistry. The President of Camelbak wrote, in response to the SIGG scandal and regarding both its plastic and stainless bottles:
Amid the potential concern about metal water bottles that this article may cause, I wanted to reassure you that CamelBak's stainless steel bottles are BPA-free, and are clearly marked as such on the bottle packaging. For plastic water bottle fans, CamelBak was first-to-market with a BPA-free hard plastic bottle in January 2008.
I want to be very clear about what we mean when we say "BPA-Free" - it means there is no BPA in our materials, and thus no BPA in the liquids that people drink from our bottles. We back this claim with continuous testing of our materials conducted by an internationally-recognized independent lab.
When we decided to make metal bottles in kid and adult sizes, we purposely chose to use medical-grade stainless steel because it does not require a liner. Aluminum water bottle liners have been a topic of concern in the industry for many years. The added benefits of stainless steel are that it's dent-resistant, stain-resistant and taste-free.

After the recent Bisphenol A scare, a lot of people are looking for new water bottles. That makes it a good time to introduce the Kor One bottle by RKS designs. It has a special flip top that can be easily opened with one hand (a must for sports like rowing or cycling) and it's made of BPA free Eastman Tritan. A bit pricey at $29 but looks good.
After a long and bruising public relations battle that they couldn't win, Nalgene threw in the towel and threw out the Bisphenol A. They now have a line of bottles in Tritan, polyethylene, PET and stainless, all labelled BPA free. We wrote about it:
