Speciation Modeling
Speciation modeling uses a chemical analysis of a water to calculate the distribution of aqueous species using an ion-association aqueous model. The most important results of speciation calculations are saturation indices for minerals, which indicate the saturation state of each mineral relative to the water. Normally, speciation modeling requires only a SOLUTION keyword data block for each water analysis for which saturation indices are to be calculated.
