Not a valid question since the level exceeds .7 ppm in numerous areas
around the country. But, many studies have shown serious health
problems such as skeletal fluorosis, kidney impairment etc. You'll
refute these I'm sure but they are well documented. Read JAMA 222:783 -
785. If you're a dentist you'll know what that is. There is concern
to many doctors with the effects on people with immune disorders and
diabetes. You seem to not point out that the body retains fluoride.
The kidney's do not remove 100% of typical daily intake. The other
issue is that intake of fluoride comes from MANY other sources besides
water. You can't avoid it. Putting it in water does nothing but
elevate the already high levels found elsewhere. Whats worse is the
form used in water. A waste byproduct.
