About Everett Water Fluoridation

November 9, 2009

Dear Mr. Deal,

The most recent Water Comprehensive Plan for Everett, which was published in 2007, estimated the service population of the combined wholesale and retail service area at 504,630. Since Snohomish county has continued to grow since that data was produced, the number served may have changed by a few thousand.

Mark says that Everett buys its silicofluoride from Cascade Columbia and LCI. They are the primary sources for information about the fluoride.

Tanker loads are delivered roughly every 20 days.

Verl Sly, 425-257-8918, vsly@ci.everett.wa.us, informed me on October 15, 2009, that the treatment plant is around four miles up hill from Monroe. Water from Spada Lake forms the Sultan River, which flows down past Lake Chapman, another water source, where there is a reservoir and a treatment plant, just south of Lake Chaplain and four miles north of Monroe. The Sultan River flows into the Skykomish, which flows into the Snohomish, which flows into Puget Sound north of Everett.

All the silico-fluoride bears the NSF 60 seal of approval. The fluoridation crew does not test the silico-fluoride before they add it to the water.  The fluoridation plant itself is managed by Del Nestigard. Everett began fluoridating in 1992. Consumption is 45-50 million gal per day in winter and 100 million gallons per day in summer

Everett has owned its water system since 1917 when it bought out a private water system.

Sodium hydroxide (Draino®) and sodium carbonate (soda ash) are used to raise the pH. To raise the pH from 3.0 to 7.4, 16 mg of soda ash are added per liter of water. Main pipes are cement lined, and this raises the alkalinity all the way to the end of the system.

The Everett Water District operates a laboratory on Smith Island.

Steve Deem Dept of Health 253-395-6767 steve.deem@doh.wa.gov, says: Drinking water regulations do not require that an assay, feedstock test, or stock solution test be done of the fluoridation materials before dilution.

The Everett web site says:

  • Four main transmission lines – ranging from 48 to 51 inches in diameter
  • Four pump stations
  • 18 pressure zones
  • 15 storage facilities – ranging from 0.1 to 24 million gallons in capacity
  • 370 miles of distribution pipeline

    The best information on fluoride you will ever hear is at the bottom of the website MaeBrussell.com. Dr. Lee, Dr. Yiamouyannis, Dr. Mullenix, and Joanie Greggains give you the history, health effects, origins, and reasons why this toxic industrial waste product is banned in most countries of the world. The audio is 75 minutes long which fits perfectly on a regular audio cd. You might consider burning hundreds of cds and circulating them around your community. The pro-fluoridationists will have a much more difficult time doing their job when surrounded by an informed public. Good luck.
