WATER FLUORIDATION STATUS:

  • PERCENT OF PEOPLE SERVED BY PUBLIC WATER SYSTEMS THAT ARE FLUORIDATED:
    2018:  59.3% – ranked #37 among the states (100% fluoridated is ranked #1)
    2016:  60.6%
    2014:  63.7%
    201263.7% (38,041,430 people)

CALIFORNIA FLUORIDE DATA FOR EACH WATER SYSTEM

2020: The most concise report on the levels of Fluoride in the State’s Drinking Water and the Fluoridation Status of each community: 

150 Public Water Systems with fluoride levels over 0.71 ppm.
• 85 systems: over 1.0 ppm
• 65 systems: 0.71 ppm to 0.99 ppm

It is illegal for any Public Water System to deliver drinking water with fluoride concentrations higher than 2.0 ppm, which is still exceedingly high. Water departments deal with this issue by using filter systems to reduce the high levels of fluoride, in some cases blending with water supplies that have lower levels, or the abandonment of the water supply.

To find out the fluoride levels in your drinking water, contact your local water department. You can also go online to CDC’s My Water’s Fluoride.

1969 Natural Fluoride Content of Community Water Supplies – Online here

“A survey to determine the number and location of community water supplies contain­ing dentally significant concentrations of naturally occurring fluorides was made in early 1969 by the State Dental Directors at the request of the U.S. Public Health Service. This publication presents the results of this survey and serves to update a similar document published in 1959.1 The 1959 publication included all communities reporting at least one water source with a natural fluoride concentration of 0. 7 parts per million (ppm) 2 or higher. This publication differs in that it lists all communities whose water supplies were reported to have a natural fluoride concentration of 0. 7 ppm or more regardless of the concentration of the various sources of water. This sur­vey attempted to identify public water systems in the United States which naturally contain the minimum fluoride concentration recommended by the Public Health Serv­ice as optimal for protection against dental caries.
“The optimum concentration of fluorides in community water supplies depends upon the annual average of maximum daily air temperatures in the individual community . According to Public Health Service Drinking Water Standards, 1962, the recommended concentrations are shown in Table 1…”

water fluoridation accidents:

  • JUNE 2002 – Dublin: Malfunction with fluoridation equipment produces fluoride levels as high as 200 ppm at local business. 23 people are poisoned. The primary symptoms are stomach pain and vomiting. (SOURCE: Contra Costa Times 2002)
  • Marin County – October 26 – November 1, 1977.
    Fluoride feeder valve malfunctioned. Five communities received fluoride above “accepted” level for several days without notice to the public. The Ind. Jrnl. reported the water district staff justified distribution of the overdosed water on the grounds it was a drought year. See article discussing this accident

CALIFORNIA’S mandatory FLUORIDATION LAW:

  • Fluoridation is mandated for communities of 10,000 or more service connections (estimated 25,000 population).
    “Outside” funds must be found for purchase, installation, and operations of the fluoridation system.
    The law does not address water supply wholesalers. The law sets a MCL of 2.0 mg/L. California’s law cannot be enforced unless “outside” funds are made available to the community for purchase, installation, and operation of the fluoridation system.
  • Read California’s Health & Safety Code on the fluoridation of drinking water.

• In California, Latino children and poor children experience more tooth decay and untreated tooth decay than other children. [3, 6, 26, 35]
• African-American adults in California have a higher prevalence of tooth extraction due to decay or gum disease, [32] and higher mortality rates from oral cancers than adults of other racial/ethnic groups. [33, 34]
• In California, 64 percent of the population receives fluoridated water from their community drinking water system, far short of the federal Healthy People 2020 target of 79.6 percent. [72]

FRACKING in the state includes the use of hydrofluoric acid. See the many news reports on this, reading the California posts, at http://fluoridealert.org/news/?industry=fracking. “…In the Monterey Shale…oil companies are using larger amounts of hydrofluoric and hydrochloric acids to open tiny channels in the rock around each well. Those channels allow oil trapped within the rock to flow into the well… Read more, Acidizing could rival fracking in Monterey Shale

The California Dental Association (CDA) announced in 2010 that the American Dental Association gave it $200,000 to work against the placement of ‘fluoride and its salts’ on the California List of Chemicals Known to the State to Cause Cancer or Reproductive Toxicity. This list is commonly known as Prop 65.
