Why Hard Water Is A BIG PROBLEM and What To Do About It

It only becomes "hard" when it comes into contact with other elements like the ground, chalk, limestone and rock – that its state can change. It is this contact that makes rain water pick up minerals like magnesium and calcium, which is the cause of "hard" water.
