Water, water everywhere, and not a drop to drink!
This is
true when you are in the middle of the ocean. It is also becoming the truth on the mainland,
where the “clean” water coming through our taps can be causing us more health
problems that we are aware. How much do you know about how the water gets to
our homes?

Fear the tap. |
From dam to our tap...
I live in Melbourne, where growing up I was told “Melbourne
water is one of the cleanest waters in the world to drink”. This may be true if
you are drinking it directly from the source (except for a recent discovery of pesticides found near one of the dams), but that water goes through a
complete treatment process before it ends up through our taps. I got these
processes directly from the
Melbourne Water website, then made my own notes on it.
Coagulation
Raw
water is pumped from the reservoir to the Winneke Treatment Plant inlet control
structure, where it is mixed with liquid aluminium sulphate (alum). The alum
acts as a coagulant, encouraging suspended solids and microorganisms in the raw
water to bind together to form larger particles.
Aluminium is a mineral commonly found in aluminium foil,
antiperspirants, antacids and food additives. It has been linked with numerous
health conditions with the most concerning one being Alzheimer’s disease. Aluminium
deposits itself in the body in the bones and central nervous system, leading to
neurotoxicity and osteopenia. The World Health Organisation (WHO) states that
although there is only a small amount of aluminium used in water coagulation,
the combined effects of the water with the use of aluminium in everyday
products and foods may be detrimental to health long term.
Clarification
The
water then flows through an underground channel to a water distribution chamber
that feeds the four clarifiers. Water is circulated in the clarifiers for about
3 hours. The clarifiers enhance the cohesion and entrapment of the suspended
solids and remove colour from the water. Solid particles are separated from the
raw water producing what is termed 'settled water' and sludge.
I wonder how often they clear out the solid particles?
Filtration
The
'settled water' is delivered through concrete channels to 12 gravity filters,
which remove most of the remaining suspended solids. Each filter is a
rectangular, concrete structure with a bed of sand supported by a layer of
course media that is supported on a layer of pebbles.
Sand filter system, this doesn’t sound too bad, does it? These
sand filters haven’t been changed for 20 years, so imagine how much gunk is in
those filters... an don't you love that it removes MOST of the suspended solids?
Disinfection and pH correction
After
the water passes through the filters, it is disinfected (by chlorination) to
destroy residual microorganisms. Lime is added to adjust the alkalinity/acidity
(pH) level. The fully treated water flows into a large enclosed storage
reservoir adjacent to the treatment plant. This reservoir is a buffer storage
and water is released as required.
Chlorine is a dangerous chemical which is a known irritant,
causing a reaction on the eyes, skin and respiratory system (companies use
chlorine to bleach paper, imagine what it does to your eyes!). The long term
effects are still unknown. This however, is not the main concern. Chlorine is
highly reactive and its by-products are considered dangerous. Known
carcinogens are formed when in contact with chlorine, which then accumulates in
our fatty tissues and has revealed to alter cholesterol levels to increase
harmful LDL as well as colorectal and bladder cancer.
And you don’t just
ingest chlorine from tap water, you also bathe and shower in it. In the warm
water your pores open up like a sponge and absorbing all the “goodness” from
your water, not to mention breathing in the steam. The heated chlorine produces
chloroform, which used to be used in surgery as a knockout gas and can cause
dizziness, headaches, abnormalities in pregnancy & sperm formation and liver
& kidney damage.

Chlorinated water: the REAL reason Janet Leigh was screaming in the shower in Psycho |
The lime process is not about adding lime fruit to the water
(a pity!). Lime water is a common name for a calcium hydroxide solution, which
is commonly used to alkalise liquids and is used in whitewash, root canal
operations, making sugar, aquariums and the traditional creation of corn food products
(tortillas, corn chips).
The list of
health risks in the use of calcium hydroxide is huge. It has been shown to lead
to breathing difficulties, internal bleeding, hypotension, skeletal muscle
paralysis and an increase in our body’s blood pH level, which can cause damage
to internal organs long term. The amount of lime used in water treatment is not
mentioned, so it is unclear how dangerous and diluted the solution will be in
the water. A clear connection between a persons health conditions and the
liming of water may never be proven.

We want this lime... |
Fluoridation
We are
required by State Government legislation under the Health (Fluoridation) Act
1973 to fluoridate the water supply. Fluoride is added in precise quantities
downstream of the Winneke Treatment Plant at Research.
Did you also know that fluoride is considered a poison? It
was once widely used as an insecticide and rodenticide and is considered to be
more toxic than arsenic!
Fluoridation of water is a controversial topic, as you talk
to any dentist and they explain the benefits of fluoridation in water as it
helps prevent tooth decay. Research has found that fluoride not only causes
further decay, but has also been linked to cause bone cancer, liver cancer,
osteoporosis, genetic damage and even deformities.
Think of your body
as a seesaw. All of our minerals are in a certain balance with each other. If
you put a large amount of one certain mineral in the mix, it is going to change the seesaw and lead
to an imbalance of the other minerals. I believe it is no coincidence that once
Australia started fluoridating its water, the incidence of osteoporosis
increased significantly, as minerals important for bone production (calcium, boron, magnesium, manganese and phosphorus) were thrown out of balance. Some countries in Europe (Germany, the Netherlands,
Sweden, Finland and the Soviet Union to name a few) have all removed fluoride
from their water due to the health and safety concerns.
And it doesn’t stop there!
This water still needs to go through our pipes to get to the
tap. What are pipes made out of?
Copper
Copper pipes are used extensively in plumbing systems throughout the world. We need copper in our diets for energy, collagen &
elastin production and hair health, but like most things in life, not too much! Unfortunately, copper pipes can corrode over time and release copper into you
drinking water. Water can remain stagnant in a tap for some time, which means
there is more copper in it. If you have noticed a green/blue stain on taps,
sinks, showers or toilets, or have noticed a metallic taste in your mouth after
drinking, this means there is a high amount of copper in your water.
Excess copper consumption can cause nausea, GIT disturbances,
headaches, diabetes, hormone imbalances
and Alzheimer’s. You can have your water professionally tested and you can even
get yourself tests by Hair Mineral analysis (a sample of your hair is tested
for heavy metals).

Mmmm... tasty water! |
Polyvinyl chloride (PVC) Pipes
This is the more modern plumbing pipe and is a form of
plastic common in todays manufacturing. In homes built before 1977, installed
PVC pipes were found to leach polyvinyl chloride into drinking water at levels
above the maximum allowed contaminant level. Levels were tested at dead-end
pipe segments, where water stagnates. Who knows how many pipes in use today are from before 1977!
The manufacture and disposal of PVC creates potent
environmental toxins. Polyvinyl chloride, the main ingredient of PVC pipe, is
classified as a known human carcinogen. Stabilizers and plasticizers used in
PVC production may contain lead or other heavy metals, and during
incineration -a common form of disposal-hydrochloric acid is released.
Hydrochloric acid is corrosive and can cause respiratory damage. This is also a
problem during building fires, where exposure to burning PVC puts firefighters
at risk. Of greater concern is dioxin, a potent carcinogen and
hormone disruptor created during PVC’s production and incineration. Though
dioxin is not present in the pipes, its emission from PVC factories and
incinerators poses a health threat to everyone.
So what can you do to help your health?
- Buy a water
filter for your drinking water
- Buy a
shower filter – trust me, it feels amazing!
- Tell your
friends & family about what they are drinking and spread the word
- If you are
concerned with copper toxicity, get your water professionally tested and
hair mineral analysis from a qualified practitioner.
A little note from me...
I will not endorse specific filter products on this blog,
however if you email me privately at
