No point here in vancouver. The water from the tap is pretty darn good.
And unless it came right out of the RO/DI unit, i'm not so sure about it once it's sat in jugs for a few days. Most places put some ozone in those jugs for a reason.
Vancouver now boasts the purest tap water in the world—so why are you still drinking bottled?:
