IONPAIR: A Chemical Speciation Program for Calcareous and Gypsiferous Soil Solutions

Abstract

Calcareous and gypsiferous soils are common along many river floodplains in the subarctic and arctic regions of Alaska as well as in more arid regions such as deserts and grasslands. The IONPAIR program was designed to speciate the chemical composition of calcareous and gypsiferous aqueous solutions. There are a number of commercially available chemical speciation programs. However, some program such as WATEQ4F do not allow PCO2 (the partial pressure of CO2G) as an input, while other programs such as GEOCHEM handle PCO2 in an inconvenient fashion requiring a trial and error approach to solution.
