Yeah, not sure how long, but out of curiosity I just had a look at the latest report from the Duteau Creek source. Note the difference in TDS! But there are still traces of nasty stuff & the calcium is much lower. Too bad there's not a way to filter everything but the calcium & magnesium out of the Kal Lake water...
