Hard water contains dissolved magnesium and calcium ions. ... Temporary hardness is caused by dissolved calcium hydrogen carbonate (which is removed by boiling).
Permanent hardness is caused by dissolved calcium sulfate (which is not removed by boiling).
Water can be softened using washing soda or an ion-exchange resin.
