I don't know about you, but my water in Broomfield leaves a pretty good bit of sediment residue on my faucets and shower heads. It looks like calcium or lime deposits or something. Kind of a white/green tint to it. I drink water from a filter in my fridge, but rarely from the tap. The times I have, it tastes fine, but I figure I'll still pre-filter the stuff I fill my storage containers with. Unless of course I'm filling them in a hurry.
