README.PhreeqcI.txt PhreeqcI Version 3.4.0 November 9, 2017 A graphical user interface to: PHREEQC--A program for speciation, batch-reaction, one-dimensional transport, and inverse geochemical calculations This file describes installing the GUI PhreeqcI on Windows operating systems. The GUI can be downloaded from http://wwwbrr.cr.usgs.gov/projects/GWC_coupled/phreeqc/index.html. PhreeqcI has screens for most PHREEQC keywords and allows input files that use any of PHREEQC version 3 capabilities. Alternatively, a Notepad++ interface for PHREEQC version 3 is available at http://www.hydrochemistry.eu/downl.html. TABLE OF CONTENTS A. Distribution file B. Documentation C.

Installing and running the GUI PhreeqcI ----------------------------------------------------------------------------------- Note: the person installing the software generally must have administrator rights. To install the GUI, double-click phreeqci-3.4.0-12927.msi to execute the installation program and follow the directions on the screen. The GUI is completely independent from the batch version. To execute the GUI, access the program through the start menus of Windows. By default, PhreeqcI is installed in the directory C:\Program Files (x86)\USGS\phreeqci-3.4.0-12927. This is the recommended installation directory, but you may use other directories or disk drives. Note that program components not installed initially can be installed later, and any components damaged (for example, by inadvertently overwriting the directory) can be reinstalled by double-clicking phreeqci-3.4.0-12927.msi--a maintenance version of the installation program will be executed. ----------------------------------------------------------------------------------- D. Testing and examples ----------------------------------------------------------------------------------- Input files are provided to verify that the program is correctly installed and running on your system. The input files execute the examples presented in the 2013 user's guide, which demonstrate most of the program's capabilities. The PHREEQC "examples" directory contains the input files. To run the examples, copy the "examples" directory (C:\Program Files (x86)\USGS\ Phreeqc Interactive 3.1.4-8929\examples) to a location where you have read/write access. The examples can be run from the new directory either by double clicking one of the .pqi files from Windows Explorer or by the File->Open menu of PhreeqcI. The examples are described in the table below, where 'Num' corresponds to the example number in the PHREEQC manual. Charts can be compared to charts in the manual (Techniques and Methods 6-A43). Num Description of example ---- -------------------------------------------- 1 Add uranium species and speciate seawater 2 Temperature dependence of solubility of gypsum and anhydrite 3 Mixing seawater and groundwater 4 Evaporation and solution volume 5 Add oxygen, equilibrate with pyrite, calcite, and goethite. 6 Reaction path calculations with K-feldspar to phase boundaries 7 Organic decomposition with fixed-pressure and fixed-volume gas phases 8 Sorption of zinc on hydrous iron oxides 9 Kinetically controlled oxidation of ferrous iron. Decoupled valence states of iron. 10 Solid solution of strontianite and aragonite. 11 Transport and ion exchange. 12 Advective and diffusive transport of heat and solutes. Constant boundary condition at one end, closed at other. The problem is designed so that temperature should equal Na-conc (in mmol/kgw) after diffusion. 13 1D Transport in a Dual Porosity Column With Cation Exchange 14 Transport with equilibrium_phases, exchange, and surface reactions 15 1D Transport: Kinetic Biodegradation, Cell Growth, and Sorption 16 Inverse modeling of Sierra springs 17 Inverse modeling of Black Sea water evaporation 18 Inverse modeling of Madison aquifer 19 Modeling Cd+2 sorption with Linear, Freundlich, and Langmuir isotherms, and with a deterministic distribution of sorption sites for organic matter, clay minerals, and iron oxyhydroxides 20 Distribution of isotopes between water and calcite 21 Modeling diffusion of HTO, 36Cl-, 22Na+, and Cs+ in a radial diffusion cell 22 Modeling gas solubilities: CO2 at high pressures ----------------------------------------------------------------------------------- E.
