Water hardness is usually expressed as the number of parts per million (ppm) of calcium carbonate present in the water (see Table 19). Share on Whatsapp. 4) 500 ppm. Very hard water is considered anything above 300 ppm. The higher concentration of Mg may be due to the geological formation of soil. Total hardness is the sum of the calcium and magnesium concentrations, both expressed as calcium carbonate, in milligrams per liter (mg/L). The calculator uses the formula below: TOTAL PERMANENT HARDNESS = MAGNESIUM HARDNESS + CALCIUM HARDNESS The calcium and magnesium stand as the concentration of both elements stated as calcium carbonate. PH Meter and TDS Meter Combo-PPM Digital Water Quality Tester-for Drinking Water. Between 120 and 180 mg/L is considered hard. 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. Naturally soft water actually leaches more contaminants from water distribution lines and plumbing systems into the drinking water supplies. .
