Thank you, Lucia for the tract from Gary Null about the chlorinated drinking water. I was wondering what effects the water would have on the kidneys, liver, etc. also? Sometimes I think I should get paid for asking questions. It's a wonder I haven't driven my husband nuts asking him stuff. I am going to talk to someone down at our local Organic Groceries about the water and filters--I'm sure they must know something about it since they are in my neighborhoood. Mary J.
