I have a well. I like my well water best.
I can't stand water that tastes faintly of chlorine and I hate that in order to get rid of that, I have to put it in a container and let it stand for a while. Actually pay for bottled water to be delivered to my office because of that (along with 11 other people in the office, we go into it together, comes out to around $2 a month per person).
