Water:  Is It Safe to Drink? Part I – Identifying Commonly Found Contaminants

It is definitely hard to know how many toxins are in water supplies in the U.S.  “Research indicates that there are 500 or more toxic chemicals in the U.S. water supply at any given time.”¹  Chlorine, fluoride, aluminum, lead, mercury, arsenic, toluene, other heavy metals, industrial chemicals, pharmaceuticals and hundreds of other non-organic and organic contaminants flow freely every time you turn on your faucet.  Enough to quench a desert thirst!  These contaminants sound bad enough at first reading but let’s take a closer look.


What would happen if you were to spill common household bleach on your skin or on an article of clothing?  You’d experience a painful skin burn or watch a hole being burned through your favorite shirt.  And, in the same manner, chlorine burns the walls of your arteries every time you drink or cook with tap water.  Injured artery walls become sites where plaques can form.

As quoted in Coronaries, Cholesterol and Chlorine by Joseph M Price, MD, “….the cause of atherosclerosis and resulting heart attacks and strokes is none other than the ubiquitous chlorine in our drinking water!”

There is a growing consensus that the majority of human cancers are caused by chemical carcinogens in the environment and, hence, that they are ultimately preventable.  Several studies have demonstrated the presence of carcinogens in treated municipal drinking water.  Other studies have shown that carcinogens are introduced during chlorine treatment.  Chlorine’s implications in both heart disease and cancer should be enough to make us take a serious look at our water supply.


What about fluoride?  A most controversial subject.  Historically sodium fluoride has been added to water but recently it has been replaced by fluorosilicic acid in about 70% of US cities. Fluoride, in any form, is extremely toxic.  It is well documented that fluoride causes the body to age prematurely by interfering with the production of collagen (a very important protein found in the body).  Collagen normally works in the body to harden (or mineralize) teeth and bones and makes skin, ligaments, tendons and muscles pliable.  As the body ages it loses the ability to determine which tissues should be mineralized.  Fluoride promotes this process and accelerates its rate of progression.  Skin tends to wrinkle due to excess mineralization.  Ligaments, tendons, cartilage and muscles become calcified resulting in pain.  Joints tend to “lock up.”

Enzymes are responsible for making the body run smoothly on a chemical level.  Fluoride also interrupts their function.  For example, fluoride bonds with magnesium and calcium to form compounds the body cannot use.  But when properly bonded, these minerals help produce the enzyme cholinesterase (an enzyme that is essential to proper brain function).  Alzheimer’s disease may develop when this enzyme system is not functioning properly.  Fluoride is also believed to be responsible for weakening the immune system and contributing to some cancers.  It also has been implicated in certain birth defects due to its ability to damage genes or DNA.  Ready to check fluoride off your list of favorite things yet?  If not, read more in Fluoride the Aging Factor, by Dr John Yiamouyiannis (available at amazon.com).  He builds a very strong argument!


In his book Zinc and Other Micro-Nutrients, the late Carl Pfeiffer, PhD, MD presents a correlation between excessive blood levels of aluminum and Alzheimer’s disease.  Of pre-senile dementia (Alzheimer’s disease) he writes:  “….victims who die of this disease always demonstrate at autopsy, 1) neurofibrillary tangles, 2) neuronal degeneration, and 3) excess aluminum in the brain and cerebrospinal fluid.  The neurofibrillary tangles have been associated with aluminum poisoning.”  Indictment enough for me!

Other common toxins

Besides the main toxins we have discussed other common toxins in water include MTBE (a gasoline additive) and perchlorate (a chemical found in fertilizers). Perchlorate adversely affects brain development as well as thyroid function in children.

Heard enough to register cause for concern?  Are you willing to consider looking for a safer water supply for drinking and cooking?  I sincerely believe this is not a difficult change, but a critical one!  So what are the choices?
