Here is a quick hard water ppm chart that gives you a spectrum of water hardness in parts per million (ppm): Scale Of Water Hardness (From Soft To Very Hard Water) The internationally recognized water hardness scale recognizes 4 water hardness classes; from soft, moderately hard, hard, to very hard.

The hard water regions (100+ ppm) include the Canadian Prairies, the U.S. Midwest, and the southwestern states of New Mexico and Arizona. In a sense, the hardness of water is the other side of the coin to alkalinity. In general terms, rainy climates such as the Pacific Northwest have acid water.

Measures of water hardness. Hardness is caused by compounds of calcium and magnesium, and by a variety of other metals. General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.
Water hardness is measured in terms of a unit called “parts per million” (ppm) or “milligrams per liter” (mg/L). There are two main methods of measuring water hardness: titration and test strips.
