How Hard is your Water?
Depending on where we live, the quality and contents of the water we use will vary considerably.
Some areas of the UK have soft water as the naturally soft rainwater passes through hard rocks which do not dissolve.
What is hard water?
In other areas, rainwater drains through softer chalk and limestone rock which dissolve. The dissolved chalk, limestone, and other minerals, such as calcium and magnesium, make the water hard and form scale.
So the hardness of your water is dependent on where you live. Sub-soil levels can also contain nitrates, pesticides and insecticides which enter our water supply and chlorine is added by some water companies for disinfection.
