My water has enough arsenic in it to be required by the EPA to notify the public. And I was at the local watering hole a few days ago, and I noticed that they had hot water on top of the coffee maker, and it had crystals floating around in it. I asked if they had put something in the water, and they said no, it's just the way the water is. I thought, Hmmm, I think I know I am getting some minerals with drinking this stuff. Not as soft as most waters in the Willamette valley, eh?
