The LLNL thermo database. This is the default dataset of thermodynamic data for the GWB applications, including log Ks for hundreds of reactions involving aqueous species, minerals, and gases; also coefficients for evaluating activity coefficients by the B-dot equation.	thermo.tdat [or GWB12 format]
An expanded variant of the LLNL database containing many organic species and radionuclides. Some people feel this database is less internally consistent than thermo.tdat, especially with respect to aluminum and sulfur species.	thermo.com.V8.R6+.tdat [or GWB12 format]
The thermodynamic dataset from Release 2.8 of the USGS's PhreeqC program, formatted for the GWB applications. (You can use TEdit to convert more recent PhreeqC databases to GWB format.)	thermo_phreeqc.tdat [or GWB12 format]
