Water Hardness Limits It is universally accepted as prescribed by WHO, World Health Organization, that water below 60 PPM is considered soft and above that it is hard. For this test, you will need a small bottle with a fitted cover and water level mark. In its place, you can use the marked container in a water hardness testing kit. You will also need some dish soap and a measuring cup.

of water.

Regions with soft water (1 ppm to 50 ppm) include the Pacific Northwest from Oregon up through British Columbia. Typically seawater's hardness is in the area of 6,630 ppm (6.63 grams per litre). In contrast, freshwater has hardness in the range of 15 to 375 ppm. Water Hardness Map of the United States, parts per million (ppm) U.S. Geological Survey Classification Water Quality Association Classification < 1.0 < 17.1: A “grain” of water hardness is comparable to 1/7000th of a pound. Formula to measure no of grains to be removed: If hardness is in MG/L or PPM, convert it into GPG by dividing it with 17.1.
