Correcting for Temperature When Calculating Calcium Carbonate Saturation

Calcium carbonate saturation is frequently of interest at temperatures other than the temperature at which the pH was measured. Because calcium carbonate saturation is influenced by temperature, error is introduced into calcium carbonate saturation estimates for temperatures other than the temperature at which the pH was measured unless temperature effects are taken into account. This article describes a method to correct for temperature effects, which allows the user to estimate calcium carbonate saturation for temperatures other than that at which pH was measured. The authors provide a tool for conducting such calculations and offer example applications, which show that the degree of calcium carbonate saturation can either increase or decrease with an increase in temperature, depending on the quality of the water in question.
