Hardness of Water | U.S. Geological Survey
2018-6-11 · 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 handled a little differently from salinity in that in some countries the degree is the unit of measure. One German degree of hardness equals 10mg/liter (ppm) of calcium and magnesium oxide or 17.8ppm of CaCO 3 in the USA. This is not at all equivalent to salinity in that a relatively low salinity water rich in calcium and magnesium could have a relatively high degree of hardness.
What is the Ideal Water Hardness Level?
2022-6-2 · Soft water – Less than 60 mg/L (PPM) or 3.5 GPG. Moderately hard water – 61 to 120 mg/L (PPM) or 3.56 to 7 GPG. Hard water – 121 to 180 mg/L (PPM) or 7.06 to 10.5 GPG. Very hard water – More than 180 mg/L (PPM) or 10.56 GPG or more. Individual scientists also offer a more detailed water hardness classification.
