Re: is tap water ok?

I was at a bar with friends the other night and ordered water assuming that they would have some kind of water purification system in place. I took one sip and couldn't drink it because the taste and smell of metal was so strong. Almost like chewing on the tip of a pencil. I had to re-order and specify bottled water.
I usually drink tap water but don't know if I'll be able to go back to it. I have been using purified water for the last 24 days on the Master-Cleanse and tap water just smells/tastes really gross now.
