OH yeah! I was INFERTILE and lived with treated tapwater ALL my life - except when we lived (sadly for only 18 months) in a house with spring-fed NONfluoridated and NON-chlorinated water.
I was pregnant by the end of that year! No, I think it was even less than that - I may have to re-edit another post I made.
Oh well, give or take three months! IOW, not only drinking, but showering and bathing, too!
