What is the hardness of my water?

Hardness is determined by the concentrations of dissolved calcium and magnesium carbonates naturally occurring in the water. Hardness is measured by the lab in milligrams per liter, or mg/L, which is equivalent to parts per million, or ppm. Our naturally soft water is in the range of 40 to 70 ppm, which is 2.0 to 4.0 grains per gallon.
