8 mar 2017 · Alkalinity is expressed as the amount of calcium carbonate (CaCO 3) in your water, although other substances can contribute to alkalinity as well. The units of alkalinity are either part per million (ppm) or mg/L. These units are equivalent, as 1 ppm = 1 mg/L. Let us say your water has a high alkalinity.
