The hardness of water is determined by parts per million (PPM) or grains per gallon (GPG). Keep in mind that 17.1 PPM=1 GPG.
Why should hard water concern me?
Hard water can be a problem by making everyday tasks much less efficient. When water is softened, only about half the soap is needed to wash dishes or do laundry. Hard water can also be a skin irritant when used for bathing.
Who will test my water for hardness?
If you are connected to a municipal supply, call your Superintendent or City Hall. If you are on a private well, YOU are responsible for the safety of the water you drink and use. You should test your well for bacteria at least once a year, and for other contaminants at least every three years.
My water is hard, what should I do?
If your water tests over 3 GPG hard, then you should mechanically soften it with an ion exchange water softener.
