Hard water is water that contains high levels of dissolved natural minerals (such as calcium and magnesium).

How is hard water formed?
Rain water is naturally ‘soft water’ and typically contains very low levels of minerals. When rain falls, it seeps into the ground and comes into contact with soil and rock. As the rain water passes through the soil and rock, it can absorb minerals (like calcium and magnesium) and become ‘hard water’. Water hardness levels can vary across the country, depending on the soil and rock types in certain regions. Hard Water does not affect the quality of drinking water and is not harmful to humans.
