What is Hard Water?
the effects of water hardness on your body and home
Hard water is water that has鈥痟igh mineral content. It is formed when water filters through deposits of limestone, chalk, or gypsum which are largely made up of聽calcium聽and聽magnesium聽carbonates, bicarbonates, and sulfates.
Hard water is high in dissolved minerals, largely鈥痗alcium鈥痑nd鈥痬agnesium. The level of hardness is determined by the amount of these dissolved minerals that can be detected. In hard water, soap reacts with the calcium to form "soap scum."
Hardness can be found in鈥�both types of water, municipal and well. It can range from slightly hard to extremely hard water.

Measuring Hardness
Measuring Hardness
The grain per gallon (GPG) is a unit of water hardness defined as 1 grain (64.8 milligrams) of calcium carbonate dissolved in 1 US gallon of water鈥�(3.79鈥疞). This is 1 part in about 58,000 parts of water or 17.1 parts per million (ppm).
For a good comparison of the relative weight and size of a grain, one standard aspirin tablet usually weighs 5 grains. You can download this chart for your reference.
| Water Hardness Description | Grains聽 Per Gallon (GPG) | Parts Per Million (PPM) |
| Soft Water | Less than 1.0 | Less than 17.1 |
| Slightly Hard | 1.0 to 3.5 | 17.1 to 60.0 |
| Moderately Hard | 3.5 to 7.0 | 60.0 to 120.0 |
| Hard Water | 7.0 to 10.5 | 120.0 to 180.0 |
| Very Hard | 10.5 and over | 180.0 and over |

Limiting Cleaning Power聽
Hard water reacts negatively鈥痶o soaps and detergents. Instead of creating a rich and foamy lather, it forms a substance that is curdy. More soap and detergent are necessary to overcome the negative effects of hard water.
