The average human adult consists of approximately 65% water. Humans can go up to 8 weeks without eating but only 3-10 days without water. Water is important in the human body for cell life, metabolic reactions, transport of nutrients, body temperature regulation, and the elimination of waste. Drinking healthy water is obviously very important as harmful toxins and organisms can enter the body via this rout easily as well.

I usually recommend to drink mineral spring water or to use a specific filtration system to filter tap water so the minerals stay in and all the harmful agents are removed. Californians, especially here San Francisco, generally believe that their tap water is healthy drinking water. I beg to differ.

I am sure that after the release of the 2003 NDRC report of California tap water the different cities listed as “unsafe” improved their water supply systems significantly.  Back then Los Angeles received generally fair marks in the report, though it cited noteworthy amounts of arsenic and byproducts of disinfectants in the water supply, among other chemicals.

San Diego got a similar grade, though the study noted that in some areas the chemical perchlorate was present in levels higher than a new state standard for government action.

And San Francisco received a more critical assessment, which noted that city water does not meet a new standard for byproducts of disinfection known as trihalomethanes that have been linked to cancer. The city has obtained an extension to meet the standards.

Another issue that deserves great attention in my opinion is the Fluoridation of our water supply.

Fluoridation of water raises several health concerns:

  • Fluoride accumulates in the body and can lead to calcifications (e.g. in the pineal gland)
  • Fluoridation of water does not lead to lesser degrees of tooth decay. Therefore it is ineffective, unnecessary, and potentially harmful
  • Children are over-exposed to fluoride, which can cause dental fluorosis
  • Dental fluorosis can possibly lead to skeletal fluorosis, rheumatic attacks, pain, and stiffness later in life
  • Fluoride can damage the brain and can impact learning and behavior. According to the US Environmental Protection Agency (EPA), fluoride has been listed among about 100 chemicals for which there is “substantial evidence of developmental neurotoxicity.”
  • Fluoride may lower the IQ
  • Fluoride may cause non-IQ neurotoxic effects
  • Fluoride affects the thyroid gland
  • Fluoride causes arthritic symptoms
  • Fluoride damages bone and may cause increase in hip fractures in the elderly
  • Fluoride may cause bone cancer
  • Fluoride may cause reproductive symptoms
  • Some individuals are highly sensitive to low levels of fluoride
  • Black and Hispanic children are more vulnerable to fluoride’s toxicity
  • Silicon Fluorides may increase lead uptake into children’s bloodstream
