The unit milligrams as calcium carbonate per liter (mg as CaCO3/L) should be used consistently to express charge equivalents of a solution. Confusion arises if this unit is used to express carbonate equivalents. Using consistent units (mg as CaCO3/L for charge equivalents), the total carbonate species was shown to be equal to the sum of the alkalinity and the acidity. Includes 1 reference, table.
