Can I use Vancouver tap water with semi-hydro?

[spinrah]

I’d like to do a trial with a new orchid in semi-hydro and I’m wondering if my tap water is pure enough to use instead of purchasing RO water? People always say that Vancouver has the purest water because it comes from rainfall and snowmelt. Heck, I only drink tap water because apparently Nestle was bottling our water and selling it back to us (no idea if that’s true). So I’m wondering if it’s safe to use our tap water for an orchid in semi-hydro?

Unfortunately I have absolutely no idea how to read this water report so I am hoping you kind folks can help me out.

Edit: I also found this one which has a physical and chemical analysis in the Appendix. Not sure which is more useful. http://www.metrovancouver.org/servic...rt-Volume1.pdf
