CHEMVAL is an international exercise on applying and validating predictive computer programmes to describe the chemistry of radionuclides in the geosphere. It is part of CEC project MIRAGE (migration of radionuclides in the geosphere.) This report is the first in a series on developing and improving thermodynamic databases for use with aqueous speciation and coupled chemical transport codes. Four thermodynamic databases used in Europe for geochemical modelling are compared: UWIST; AERE, Harwell; CHEMVAL stage 1; EIR. The number of aqueous species and solid species as well as components in each database is listed. There are many cases where numbers in the different databases are not directly comparable, in which case they are not compared here and the reasons are noted.
