Water Hardness in Australia

 

 
shutterstock_146711282Laundry detergents work better in “soft water.” Borax naturally softens hard water making almost all detergents more effective so adding 1/2 cup to each full load of washing with your normal detergent will boost your detergent greatly, resulting in a whiter and brighter wash.

The ‘hardness’ of water relates to the amount of minerals it contains, such as mainly calcium and magnesium, and to a lesser degree  iron, manganese and barium salts.

 

The Australian scale is as follows:

Water Type Hardness in mg/L
Soft 0–60
Moderately hard 61–120
Hard 121–180
Very hard ≥ 181

 

And here is a guide to the water hardness in Australian capital cities:

City Total Hardness as Calcium Carbonate mg/L
Melbourne 10 – 26
Hobart 5.8 – 34.4
Darwin 31
Canberra 40
Sydney 39.4 – 60.1
Perth 29 – 226
Brisbane 100
Adelaide 134 – 148
