Fluoridation in drinking water is a practice with the intention of improving a citizen's dental condition. However, fluoride has been known to have many detrimental effects. This article explains how fluoride has been seen in studies to cause enough brain damage to reduce children's IQ versus children who have not had fluoride exposure: http://www.hsph.harvard.edu/news/features/fluoride-childrens-health-grandjean-choi/

"Based on the findings, the authors say that this risk should not be ignored, and that more research on fluoride’s impact on the developing brain is warranted." (From above article.)

In the below link, you can see Dr. Yolanda Whyte's presentation on the dangers of fluoride: http://fluoridealert.org/fan-tv/dr-whyte/

Below is another article listing numerous licensed dentists who have been open about the risks of fluoride:

If the validity of any of these documents is questioned, one's own personal research can lead them to the same conclusion that fluoride is more harmful for one's body than is worth the anticavity benefits. Here is a link to the Washington State Department of Health's page on water fluoridation: http://www.doh.wa.gov/DataandStatisticalReports/EnvironmentalHealth/DrinkingWaterSystemData/FluorideinDrinkingWater.aspx

You can see none of the adverse health effects are listed, and only the anticavity benefits, despite the credible research done to prove otherwise. 

It could be argued that one could filter their own drinking water to remove fluoride themselves, but the most common, and least expensive, water filters do not work to remove fluoride. This includes all of the popular brands, such as Brita or Pur filters. Reverse osmosis or distillation must be done to remove fluoride, both expensive methods that are not within everyone's means. 

The question is: do you trust that fluoridation should be mandatory? If you feel any doubt about whether or not it is necessary, sign this petition! We would like the option of adding unfavorable chemicals to our water!

It is our right to dictate what is in our drinking water, and fluoride should not be on that list. Fluoride should not be added to - and, in addition, removed from - the drinking water in Washington State.
