Is There Fluoride in Seattle Water?

Fluoride in Seattle Water


Yes, Seattle water has fluoride in it.

  • More than 80% of U.S. cities with populations over 50,000 have fluoride in their water.

Seattle Public Utilities reports that:

  • Fluoride occurs naturally in soil and water.
  • They also add fluoride for tooth decay prevention.
  • From 1970 to 2011, fluoride levels were set at 1.0 parts per million.
  • 2011 to 2016, these levels were reduced to 0.8 parts per million.
  • The current concentration is 0.7 parts per million.

Why is Seattle Water Fluoridated?

Fluoride is a natural occurring chemical in groundwater.

It is also added to city water supplies to help prevent tooth decay.

It does this by coating the surface of your teeth and attracting minerals lost to oral bacteria.

While controversial in many cities, preventing cavities and decay boosts overall health and well-being.

Can You Remove Fluoride from Water?

Yes, you can. Water filters with activated carbon can reduce the levels of fluoride by up to 97%.

If you want less fluoride in your drinking water, you can filter it out.

In addition, quality carbon filters will also remove other harmful chemicals.

For example, Seattle residents can remove these with a Berkey filter:

  • Chloroform – 99.8%
  • Chromium – 99.9%
  • Haloacetic acids – greater than 98%
  • Strontium – 95.3%
  • Total trihalomethanes – greater than 99.8%
  • Vanadium – greater than 87.5%
