water-rock interaction and
geochemical modeling made simple

Now available for download: Sym8.EQ Speciation Model

for Windows and MacOS: version 1.0.2a, download for free
iOS (iPad) version coming to Apple Store later this year

Coming soon: Sym8.BK Batch-kinetic Model

Can Sym8 be really different from other water-rock interaction simulators? Find out — details are forthcoming.

Sym8.EQ update will include redox reaction options and basic plotting utilities.

Sym8.BK version 1.0-beta is nearing its release. This program is built around kinetic reactions and petrophysics composite media modules. See what it can do in upcoming examples page.

User interfaces are in development for batch/kinetic model to be released soon and 1D reactive-transport simulator to be released in late 2026. 2D option will follow.
