Your welcome. I always try to provide my sources.
Thanks for the information posted above from your link you so kindly provided......
Enough said I think.
I wonder what "more recent" research Dr. Limeback was talking about. The pieces of research cited in my post are from 2001.
Here's one from 2007:
The prevented fraction for water fluoridation was 27% (95%CI: 19%–34%). These findings suggest that fluoride prevents caries among adults of all ages.

Brushing your teeth with fluoride is a really good idea too. According to the study it prevents the same number of caries as fluoridation. So if you have both you should have more the 50% fewer cavities than someone who doesn't.
Wallowing? Really? I don't see it.

it is either a safe toxin (which I have never heard of in my life) or it is just that....a Poison.
Lead paint was banned 35 years ago. The use of friable asbestos (the harmful stuff) was banned in various uses starting in 1973. Encapsulated asbestos (which cannot be inhaled) is allowed.
For christ sakes they were coating children's toys with asbestos and lead paint just to be sure they were not going to burn up or the paint stayed put.

Sure it is, when it is in high enough concentrations. So, any concentration is bad? Do you drink coffee? Tea? Maybe even an occasional soda? Do you drink undistilled water? All of these contain "poisons".
Oh come on. No vices? You can tell us.
To answer your pop quiz no to all of the above and I am being honest here.
RO Water only here.

But RO water is not distilled. There will be low concentrations of those poisons.

Anything banned 35 years ago is still kicking today, think about it for a minute how do you remove lead paint that has 7 coats of paint over it.
How do you remove asbestos coated walls and pipes? The only solution I see is to demolish the building and then refuse treatment to those who suffer the consequences.
What effects? You mean fluorosis? You can't do much about it but it takes drinking water with pretty high concentrations for it to show up. That other stuff? Cancer? Neurological effects? There doesn't seem to be much evidence that it can be blamed on fluoride in water, in particular at the low concentrations which are involved with fluoridation.
How do you remove the affects of ingesting Fluoride over a life time?

Your point seems to revolve around dental health benefits, yet the data you have provided doesn't prove it is beneficial to dental health (in fact there is evidence to the contrary).
Comparisons of communities where water is fluoridated and communities where water remains unfluoridated show a reduced prevalence of dental caries in the range of 18-40 % when fluoridation is used (4). A recent study established the rate of caries reduction at 25 % (23). It is postulated that this estimate is more conservative than those reported in the past because the general population now enjoys the benefits of fluoride from other sources,
such as fluoride-enriched toothpaste and vitamin supplements.
The prevented fraction for water fluoridation was 27% (95%CI: 19%–34%). These findings suggest that fluoride prevents caries among adults of all ages.
Evidence that fluoride is toxic at the concentrations involved with fluoridation is lacking. There is certainly no proof (you seem to like that word) of it.
what good does adding a neuro-toxin to our drinking water do?
What are the risks of a concentration of 1ppm of fluoride in drinking water? As the study shown above indicates fluoridated water provides an 27% benefit.
Do the benefits really outweigh the risks, when we consider the fact it's already in tooth paste, and that is the primary reason cited for it's use in drinking water?
Ah. So you complain about a lack of "proof" that fluouride is beneficial and offer "evidence" as a counterpoint. That's a bit unfair don't you think? The fact is that there is very strong evidence that water fluoridation is beneficial. Did you miss this?
Evidence that fluoride is toxic at the concentrations involved with fluoridation is lacking. There is certainly no proof (you seem to like that word) of it.
What are the risks of a concentration of 1ppm of fluoride in drinking water? As the study shown above indicates, the direct application of fluoride results in a 29% percent decrease in caries (in adults). Fluoridated water provided an additional 27% benefit.
Not if I thought there was a chance of "poisoning". I don't think there is. Nor, apparently, do the voters of Gilbert and other communities. I wonder if there has been any increase in neurological problems in their children or themselves over the past 12 years.
Are you willing to tell me that you would be willing to potentially poison your own child, possibly lower his or her IQ, etc etc, all for an additional 29% reduction in CAVITIES? really?
It pretty much is. In some places it's a bit higher, in some a bit lower. The data is quite readily available for different communities. If natural levels exceed that none would be added.
-Whether or not this number is standardized and if certain drinking supplies are fluoridated over this amount
Let's say all the water an adult drinks is from a fluoridated water supply. 64 ounces a day would be 690 liters a year. At 1ppm that comes out to 690 mg of fluoride a year. About 3 ibuprofen tablets and of course, not all of that is utilized by the body nor does it occur all at once.
-How much fluoridated tap water a given individual ingests in a year
Well that's a little harder to figure out, an awful lot of variables.
-How much of that fluoride is in addition to what the individual already ingests through food, tooth paste, etc
At 1ppm concentration artificially fluoridated water would not lead to toxic levels. Of course if you eat a lot of toothpaste that could change. But if you're worried about that and live in a location with fluoride (natural or otherwise) in the water maybe you could just stop using a toothpaste which contains that "neurotoxin" and in order to reduce the risk.
How these factors (in combination with using fluoridated tooth paste) could lead to excess amounts of consumption of a neurotoxin.

Abstract
Fluoride (F) is known to affect mineralizing tissues, but effects upon the developing brain have not been previously considered. This study in Sprague-Dawley rats compares behavior, body weight, plasma and brain F levels after sodium fluoride (NaF) exposures during late gestation, at weaning or in adults. For prenatal exposures, dams received injections (SC) of 0.13 mg/kg NaF or saline on gestational days 14-18 or 17-19. Weanlings received drinking water containing 0, 75, 100, or 125 ppm F for 6 or 20 weeks, and 3 month-old adults received water containing 100 ppm F for 6 weeks. Behavior was tested in a computer pattern recognition system that classified acts in a novel environment and quantified act initiations, total times and time structures. Fluoride exposures caused sex- and dose-specific behavioral deficits with a common pattern. Males were most sensitive to prenatal day 17-19 exposure, whereas females were more sensitive to weanling and adult exposures. After fluoride ingestion, the severity of the effect on behavior increased directly with plasma F levels and F concentrations in specific brain regions. Such association is important considering that plasma levels in this rat model (0.059 to 0.640 ppm F) are similar to those reported in humans exposed to high levels of fluoride.
