The following PHREEQC input code may be used in conjunction with the frezchem.dat database. For example, this code may be pasted into the interactive version of PHREEQC (available at https://wwwbrr.cr.usgs.gov/projects/GWC_coupled/phreeqc/). Note that the frezchem.dat database needs to be selected independently from entering the input code below. If using the interactive version of PHREEQC, the definitions of all input parameters given below are well-described in the program. We have commented on the code primarily to specify the source reference for specific parameters.
