I am the author of PHREEQC, which can be used for many of the same
calculations as EQ3/6, but I do not maintain or distribute EQ3/6 or its
database.

At times, EQ3/6 databases are available from LLNL over the internet.
Recently, the old web addresses are not accessible, so I don't know where
you can get EQ3/6 databases. The latest version of PHREEQC and PHREEQCI
(version 2.3, with 2.4 to be released within the week) has a database named
llnl.dat that is derived from thermo.com.V8.R6+.dat. This should be a more
recent version than the one you mention. llnl.dat should be very similar,
except it does not include the data for most of the organic ligands.

I don't know about compliance with SUPCRT.

PHREEQC and the interactive version PHREEQCI is available from
http://water.usgs.gov/software, or
https://wwwbrr.cr.usgs.gov/projects/GWC_coupled. For EQ3/6 you should try to
contact Tom Wolery.

 Hello. I have a question. May be you could help me and I´d be very pleased
for that.

I´d need employ the EQ3/6 code for modeling the interaction
groundwater-rock in a christaline masif. What termodinamic data base should
be good for modelling, due to the one used up to now DATA0-V7-COM-R22
dispose of a little amount of data for aqueous complex formation, not
enought for my pretensions. This data base should have to be compliance
with SUPCRT (SPRONS98). Do you know any one accessible from internet?
Thank you very much and best regards.
