Which parameter is determined by calcium carbonate saturation according to the governing code?

Calcium carbonate saturation tells you whether calcium and carbonate in water will stay in solution or tend to precipitate as CaCO3, which controls the formation of scale. This saturation state is directly linked to the portion of hardness that comes from calcium reacting with carbonate species—often called carbonate (temporary) hardness. When the water is at CaCO3 saturation, the amount of calcium tied up with carbonate dictates how much of the hardness is present in the dissolved form versus precipitated as scale, which is why hardness is determined by this saturation concept in the governing code. Dissolved oxygen isn’t governed by carbonate chemistry, and while pH and alkalinity influence CaCO3 saturation, they aren’t the parameter identified by saturation itself.
