AquaChem – Water Quality Analysis Software
On June 21, 2023, we are releasing AquaChem v12.0 which introduces new functionality and incorporates client feedback on improvements to make the product even better.
New Features:

Integrated Geochemical Modeling Using PHREEQC
AquaChem provides integrated cross-functionality with the basic features of PHREEQC, the popular geochemical modelling program developed by the USGS.
- Thermodynamic Databases: Import thermodynamic databases into the project and map database
species to project parameters
- Saturation indices/Activities: Calculate the saturation indices and activities for one or more similes and seamlessly reimport the results into the project database, in a few button clicks
- Basic Geochemical Modeling: Prepare basic geochemical models of one or more samples
- Basic simulations include a streamlined graphical interface to include a variety of physicochemical processes occurring simultaneously or in a series of sequential steps, including:
- Mixing
- Changes in Temperature and/or Pressure
- Reversible and Irreversible Reactions, and
- Phase Reactions such as:
- Solution/dissolution with equilibrium phases,
- Sorption/desorption via exchange assemblages,
- Solution/Gas phase assemblages
- The resulting PHREEQC input file can be run directly from within the AquaChem interface and results can be imported into the database for further analysis and visualization, including plotting, mapping, and reporting
- The resulting PHREEQC input file can be supplemented with user-generated inputs, for scenarios where advanced users require some additional complexity
- Basic simulations include a streamlined graphical interface to include a variety of physicochemical processes occurring simultaneously or in a series of sequential steps, including:
- Advanced Geochemical Modeling: Quickly and easily migrate samples to the PHREEOCi/PREEDC for Windows interface in a few clicks, when more advanced modelling is required

Map Viewer

- Callouts: add data-rich callout features to some or all the features in a Location Data layer:
- Mini-Tables: add tabulated data for select fields in the location data layer
- Plots: add any supported plot type from the plot collection module
- Surfaces: create surfaces with colour floods and/or contours by interpolating data from a selected field in a location data layer. Supported methods include kriging, inverse distance, and natural neighbours
