Hardness of water in dublin ca
WebWhen the concentrations of calcium and magnesium in the water are known, hardness can be calculated, using the following formula: Water hardness = 2.5Ca + 4.1Mg. Where calcium and magnesium are measured in ppm (1ppm=1 mg/L). For example, water with 50 ppm Ca and 15 ppm magnesium will have hardness of: 2.5×50 + 4.1×15 = 186.5 mg/L … WebHardness Water is considered soft if total hardness is less than 75 ppm, moderately hard at 75 to 150 ppm, hard at 150 to 300 ppm, and very hard at 300 ppm or higher.
