Safe for the Environment

Water fluoridation is the single most effective public health measure to prevent tooth decay. Fluoride is a natural mineral that is found in almost every water source on earth. Fluoridation is the adjustment of the naturally occurring level of fluoride to the optimal level of 0.7 ppm (parts per million).

No credible studies have shown adverse effects from the optimal fluoride level on any living organism, including salmon. In fact, salmon spend most of their lives in the ocean, which naturally contains 1.2 – 1.5 ppm (parts per million) of fluoride—double the concentration of fluoridated municipal water.

The average concentration of fluoride in the Columbia River is 0.12 ppm. If all the added fluoride in the Bull Run water supply somehow ended up in the Columbia River, it would only increase the river’s fluoride concentration by 0.00047 ppm of fluoride, or 0.4% – far less than natural year-to-year variability of the river’s concentration of fluoride [53].

Healthy and Safe

Pew Charitable Trusts has identified over 3000 scientific studies that have been completed on community water fluoridation. The overwhelming evidence—plus more than 65 years of experience—supports the safety and effectiveness of this public health practice. Every respected health authority that has taken a position on the issue endorses fluoridation as a policy that benefits the public’s health.

Fluoride Compounds are Extremely Pure

Fluoridation products used for drinking water treatment are evaluated to the criteria specified in the National Sanitation Foundation’s (NSF International) Standard 60. Verification testing by independent certification entities documents that the actual purity of fluoride additives far exceeds the NSF Standard 60 requirements [54]. This guarantees that fluoridated water is extremely safe and pure. For example, you would receive more than 290 times the amount of arsenic by drinking a cup of tea as you would by drinking a glass of fluoridated water [55].
