water hardness scale

How hard is the water in Australia according to the water hardness scale?

Drinking water contains a wide variety of minerals. Rainfall is labeled “soft” as it has never come in contact with minerals. Water collects dissolved solids when it flows through rocks and other substrates. Water with higher-than-normal levels of soluble minerals like calcium and magnesium is referred to as hard water which is on top of the water hardness scale. Soft water has quite a lower mineral quantity, which means your family’s hair and skin will be silkier & is on the bottom of the water hardness scale. Water hardness varies considerably depending on the natural environment in the catchment region. Which one to use, hard water or soft water? Both have advantages and disadvantages, and it is all about personal preference.

Lake Burragorang near Warragamba supplies 80 percent of Sydney’s water. This water is then purified through filtration plants, which are controlled 24/7 to make sure that the water is clean. Before the filtered water reaches our taps, they add fluoride and chlorine. While drinking water quality in Australia is strictly regulated, water hardness is not. As a result, we can observe that the source of the water in Australia has a significant impact on how hard or soft it is. Total dissolved solids (TDS) are the total quantity of these dissolved minerals and are generally measured in parts per million (mg/l) or milligrams per litre (mg/litre) units. Hard water is defined as having a high mineral concentration, measured in milligrams per litre.

The water hardness scale:

  • mild below 60 mg/l
  • moderately hard between 60 and 120 mg/l
  • hard between 120 and 200 mg/l
  • extremely hard beyond 200 mg/l

A significant mineral concentration, greater than 60 milligrams per litre, is required for water to be classed as ‘hard.’

Usually, in the water hardness scale, high hardness is defined as 200 mg of calcium and magnesium salts per litre of water. Water with less than 60 mg/L is considered “soft.” Sydney’s water is classified as “soft,” having a hardness level of around 50mg/L. The hardness in the water hardness scale varies considerably between Australian capital cities. 

While it is just above 10 mg/l in Hobart, Brisbane and Adelaide have some of the toughest water, with levels reaching around 100 mg/L.Canberra, Sydney, and Darwin are located somewhere in the middle. Victoria and Tasmania get the soft water & Western Australia and South Australia have hard water. 

Without a question, drinking filtered tap water exposes you to chemicals and contaminants. One may decide to purchase a water filtration system in order to remove any residual pollutants from their tap water. Consider the frequently utilized gravity water filtration. Using a filter makes guarantees your safety. Heavy metals, contaminants like chlorine, and potentially harmful parasites can all be removed by filtration.
