from mercola.com: Water fluoridation is considered one of the most notable advancements in public health, and cities around the US spend millions adding fluoride to communal water supplies each year. But, as stated in the video above, 99 percent of that fluoridated water ends up on your lawn and in your toilet, where it’s really nothing but an environmental pollutant. Then there’s the issue of safety when ingested on a daily basis...
An increasing number of dentists and scientists are raising serious concerns about these chemicals, which by the way have never been approved by the Food and Drug Administration (FDA) — the agency responsible for food and drug safety. Many do not realize that fluoride is a drug that is available only with a prescription. Yet it's added to municipal water supplies used by more than 180 million Americans, including infants and the elderly without any attention to personalized dosing or potential interactions.
This is a significant problem, because once you add it to the water supply, you have no way of determining how much of the drug any particular person will consume on any given day. Also consider this: It is illegal, medical malpractice, and unethical for a physician to prescribe a drug without specifying dosage, and to fail to monitor your health for side effects from the drug. Yet, your water authority is not only allowed, but encouraged to add a toxic drug — fluoride — to your drinking water without your consent and without any way of knowing who in your household is drinking it, how much, and the effect it is having.
Worse yet, while scientific studies have been done on pharmaceutical grade fluoride, none have been made on the fluoride that is actually used for water fluoridation. This chemical (hexafluorosilicic acid) is an industrial waste product that is likely to be even more toxic than medical grade fluoride. It’s illegal to dump it into rivers and lakes or release the parent gases into the atmosphere. In fact, municipalities that decided to stop fluoridating their water had to keep going until all the chemicals were used up because they couldn’t afford the hazardous waste disposal fees!
