It turns out the joke is on me. A few years ago when I bought my first SIGG aluminum water bottle, I was touting my $30 purchase as an example of health and eco-responsibility. I was keeping plastic out of landfills and keeping cancer-causing Bisphenol-A (BPA) out of my body. Well, this week we learned that only the first one might be true, as SIGG CEO Steve Wasik explained in a press release that the company’s bottles made prior to August 2008 “utilized a water‐based epoxy liner which contained a trace amount of BPA.”

Wasik contends that thorough testing proved that no BPA was able to leach into the water in any of his bottles, and that bottles made after last August now use a BPA-free EcoCare liner. But now many eco-pundits and outdoor enthusiasts are feeling deceived and not being shy about it. I can’t say that I blame them. It seems like every time you try to do something better for yourself, you find out it’s actually killing you. That generalization might be a little extreme for this situation, but hopefully the backlash will ignite some pressure for transparency when it comes to companies claiming to be conscious.
