CCPP calculation using the PHREEQC program

Mr. Parkhurst,
Metropolitan has been using the USGS program to calculate saturation index
(SI) for our waters.  According to the "Standard Methods for the Examination
of Water and Wastewater", this program also calculates the calcium carbonate
precipitation potential (CCPP) which predicts the quantity of calcium
carbonate that may precipitate or dissolve in a given water.  Can we use the
same program for SI to obtain data for CCPP?
