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?
