Why Filter Your Water?
Australia is a first world country and its mains water is safe to drink. So why pay money to have it filtered?
Just because it’s safe doesn’t mean it is good for you or isn’t causing some harm to some aspect of your health.
Firstly, let’s look at what’s in your water
All water sources, whether mains water, bore water, or rain water, contain a variety of chemicals, bacteria, and acidity. Most of these unwanted bi-products are harmless in this diluted state; however, in the long term, they can affect your health, your skin and hair, the taste of the water, its ability to clean your home, and even cause damage to your home’s infrastructure.
Chemicals and toxins in your drinking water
Chemicals and other toxins are either added to, or remain in the water we drink whether it is from mains, rain or bore source supply.
In Western Australia, we entrust water treatment facilities with the responsibility of providing safe drinking water, but they only test and regulate a stipulated number of contaminants. Some chemicals like chlorine and fluoride are deliberately added to the tap water for specific purposes including the disinfection process, which is used to rid the water of harmful micro-organisms.
Other contaminants that can be found are: lead; by-products called trihalomethanes (THMs) that form when the chlorine reacts with organic matter in the water; chromium and arsenic (which is naturally occurring in certain types of rocks and can potentially contaminate groundwater and underground reservoirs).
There are several other contamination risks that can also enter the waterways from industrial effluent directly emptied into the ground water systems or from contaminated soil.
All in all it adds up to a pretty toxic cocktail, albeit diluted.
Let’s look at the most relevant additives and chemicals found commonly in unfiltered water.
Flouride was introduced to Australia’s drinking water.
In Western Australia, water fluoridation commenced in Perth in 1971. Currently, 90% of the state’s communities have access to reticulated water with accepted levels of fluoride.
There is a lot of controversy on this topic. Many countries, including Australia, choose to fluorinate drinking water due to the belief that it acts as a repair kit for teeth. There is strong opposition, though, due to the fact that fluoride can also cause damage to general health, compared to its purported benefits for dental health. The Fluoride Action Network has cited numerous studies that link several health issues to it found in the water. There are a growing number of developed countries that have earlier implemented drinking water fluoridation but, in the light of new research, have since stopped the practice.
Remove chlorine
Chlorine is a chemical which comes in several forms and is used to disinfect water in salinisation treatment plants and swimming pools. The Chlorine is a pungent smelling gas known to irritate the nasal passages, but this chemical can work effectively to destroy pathogens found in water to reduce the risks of waterborne diseases such as typhoid, viral hepatitis, cholera and salmonellosis.
The downside is that it can cause many health problems, including certain types of cancer. It is commonly added either as compressed chlorine gas or liquid sodium hypochlorite solution or calcium hypochlorite in powder form.
Lead can affect our system.
Lead can be found in water, and old metal fixtures connecting the house supply to the mains is usually the source.
Unlike chlorine, lead dissolved in water does not cause any changes in colour, smell, or taste, so the only option is to get the tap water tested as recommended by an expert.
Lead is extremely toxic, in particular it can affect the neuromuscular system and causes symptoms ranging from abdominal problems and fatigue to cognitive decline and irreversible brain damage.
By filtering your water you are able to remove these toxic chemicals, removing these potential health threats and improving the taste of your water.
Bacteria is commonly found in drinking water
Most of the bacteria in the water we drink are completely harmless. However, bacteria commonly found in drinking water creates conditions which enable other potentially harmful bacteria to thrive. Biofilms can form on all water pipes which is totally normal and this bacterium is usually not harmful. The problem that arises is that biofilms can also be a safe place for harmful bacteria such as Escherichia coli or Legionella to hide. Essentially creating a breeding ground for other, more harmful bacteria. If the bacterial growth is too heavy, it can break off into the water flow, which at best can make water discoloured or taste unpleasant and at worst can release more dangerous bacteria.
By filtering your drinking water you are removing this bacteria and removing this potential health threat and increases your chances of boosting your immunity, gut health and skin health.
Soften your hard water
Much of the water we use contains traces of minerals. Water is considered hard if it has a high concentration of dissolved minerals like magnesium and calcium in it. These elements are picked up by groundwater as it passes around and through soil and rocks.
Although hard water is not considered dangerous, there are some issues that make it problematic.
Hard water damage to your home & Body
Over time mineral deposits from hard water can build up, erode and discolour shower heads, plumbing fixtures, drains, water appliances (like your washing machine) and rubber faucets creating leaks and significant damage. Washing in hard water can cause your skin to be dried out and itchy. If you have skin conditions like eczema, dermatitis and Psoriasis, it will cause these conditions to flare and inflame. Washing hair in hard water can contribute to mineral build up and that makes it dry and straw like.
