The graphical user interface to the geochemical modeling engine PHREEQC built into AquaChem. It supports the most commonly used features and allows AquaChem to use samples as input and read simulated samples back to the database.
Advanced
You can choose to run either the USGS PHREEQC-Interactive program, or the PHREEQC for Windows. In each case, AquaChem takes selected samples from the AquaChem database and passes these to the PHREEQC graphical interface program to use as 'solutions' in the water quality simulation.
Direct link to PHREEQC to calculate the saturation indices, activities or pH for selected water quality samples and seamlessly save the results back into the AquaChem sample database
Built-in link to the USGS PHREEQC-Interactive program for complex water quality modeling using solutions generated from AquaChem samples
In table view and sample details window, display a color legend symbolizing the color for each exceedance level.
Interactive
A Windows graphical user interface for the PHREEQC program. PHREEQC-I is a public domain program developed by the USGS and is available to download from the USGS Water Resources Software website:
A 32-bit Windows version of the geochemical model PHREEQC. PHREEQC for Windows contains the full functionality of PHREEQC v.2. The input files for the program are backward compatible with the normal version of PHREEQC. This means that you can use any file created with the normal version in PHREEQC for Windows.
AquaChem can generate input data for a PHT3D simulation. PHT3D simulation requires units of mol/l, and the solutions require special conditions such as perfect ion balance, total inorganic carbon entry instead of alkalinity, etc. Therefore laboratory results have to be transformed before the data may be used in PHT3D. AquaChem allows for export of the information stored in its database into the format that can be imported into Visual MODFLOW. Visual MODFLOW includes an import feature, which allows the user to import solutions, minerals, gas composition and exchanger composition into a selected set of cells.
Calculate Saturation Indices and Activities
Use PHREEQC to calculate the saturation indices or activities for selected water quality samples and automatically store the results back into the AquaChem sample database record.
Calculate pH
Use PHREEQC to calculate the pH for the selected water sample. This tool can be used to estimate a missing pH value for an individual sample, or to validate a measured pH value.
Calculate Eh
Use PHREEQC to calculate the Eh for the selected water sample. You can use PHREEQC to calculate the Eh by means of the redox speciation with the Nernst Equation. Each redox couple, e.g. Fe2+/Fe3+,
Mn2+/Mn3+ gives an individual Eh value, which in cases of equilibrium conditions, should be reasonable.
All plots are dynamically linked to the Sample List and are updated on-the-fly as samples are added and removed or as data is modified

Detailed Description of AquaChem Plots
X-Y Scatter Plots
A simple approach to the interpretation of geochemical data. Single plots of ion relationship and parameters that show significant data can be easily created and patterns are quickly identified and easily understood. Both normal scale and log scales are supported for the x and y axes and multiplication factors can be applied to either the x or y parameter.
Parameter ratios and sums may also be included for either axis.
Ludwig-Langelier Plots
Similar to the projection areas of Piper and Durov diagrams. Suitable groupings of cations and anions are selected and plotted as percentages of milli-equivalents.
All major elements can be displayed in one plot with the Ludwig-Langelier diagram. However, like the Piper and Durov diagrams, it displays relative ratios rather than absolute concentrations.
Wilcox Diagram
Can be used to quickly determine the viability of water for irrigation purposes based on conductivity and SAR values.
The Wilcox plot is also known as the U.S. Department of Agriculture diagram.
The Wilcox plot is a simple scatter plot of Sodium Hazard (SAR) on the Y-axis vs. Salinity Hazard (Cond) on the X-axis. The Conductivity (COND) is plotted by default in a log scale.
Geothermometer Plots
Geothermometer plots can be used to test the quality of geothermometer estimates for a given geological and hydrogeological condition.
Meteoric Water Line
The standard way to portray measurements of stable isotopes from water.
Consists of a scatter diagram showing 18O on the x-axis and 2H on the y-axis. The meteoric water line is where most precipitations and groundwater fall. In cases where the measurements are shifted from this line, the type of shifting provides important information regarding to the process leading to the observed shift.
Box and Whisker Plot - Time-Series
Displays a statistical summary of any measured database parameter(s). It is composed by a central box showing the spread of the bulk of the data (interquantile range) and the whiskers, showing the length of the tails.
Box and Whisker Plot - Multiple Parameters
Displays a statistical summary of multiple measured database parameters, at a selected station location.
The plot displays the following statistical analyses:
Minimum measured value
Q1: the first quartile (25th percentile), 25% of the data lie below this value
Q2: the second quartile (Median), 50% of the data lie below this value;
Q3: the third quartile (75th percentile), 25% of the data lie above this value
Maximum measured value
Box and Whisker Plot - Multiple Stations
Displays a statistical summary of any measured database parameter, at multiple station locations.
The plot displays the following statistical analyses:
Minimum measured value
Q1: the first quartile (25th percentile), 25% of the data lie below this value
Q2: the second quartile (Median): 50% of the data lie below this value
Q3: the third quartile (75th percentile), 25% of the data lie above this value
Maximum measured value
Frequency Histogram
Most commonly used to check the number of populations within a given range of measured values.
View a large number of samples without the diagram becoming too cluttered with data points.
The Frequency Histogram can be used to plot all samples in the open database or selected sample groups. The range of values can be customized up to 10 or more groups and the individual samples can be identified at the associated value along the x-axis.
Quantile Plot
Identify the ranked data from lowest to highest on the background of lines that denote Q25, Median, and Q75.
Quantile are used to determine if two data sets come from populations with a common distribution.
Detection Summary
Used to visualize the relative proportions of samples above the specified water quality parameters. The plot shows a summary bar for every specified parameter.
Piper Diagrams
Plots the major ions as percentages of milli-equivalents in two base triangles.
This plot reveals useful properties and relationships for large sample groups. The main purpose of the Piper diagram is to show clustering of data points to indicate samples that have similar compositions.
The Piper diagram can be used to plot all samples in the open database or selected sample groups.
Durov Diagrams
An alternative to the Piper diagram which plots the major ions as percentages of multi-equivalents in two base triangles.
This plot reveals useful properties and relationships for large sample groups. The main purpose of the Durov diagram is to show clustering of data points to indicate samples that have similar compositions.
The Durov diagram can be used to plot all samples in the open database or selected sample groups.
Other options include individual multiplication factors for each selected ion to prevent data point accumulation along a base line.
Ternary Diagrams
Used to identify trends and relationships between groups of samples. It is generally easier to understand than Piper or Durov diagrams since it involves fewer parameters and does not project data points onto a grid.
The Ternary diagram plots the ions as percentages of their concentration value and is not limited to using only meq units.
The Ternary diagram can be used to plot all samples in the open database or selected sample groups. Other options include individual multiplication factors for each selected ion to prevent data point accumulation along a base line.
Schoeller Plots
Semi-logarithmic diagrams developed to represent major ion analyses in meq/l and to demonstrate different hydrochemical water types on the same diagram.
This graph has the advantage of displaying and comparing actual sample concentrations.
The Schoeller diagram can be used to plot all samples in the open database or selected sample groups only.
Giggenbach Triangle
This diagram is commonly used for geothermal exploration and allows estimation of the degree of equilibrium achieved with the host rock as well as the original subsurface temperature.
Time Series Plots - Multiple Stations
Displays the evolution of a physical or chemical parameter for multiple sampling locations, as a function of time.
Plot is a standard technique for interpreting hydrochemical and hydrogeological processes in natural waters. Regulatory standards can be plotted as horizontal lines to visualize exceedances.

Options for the time period over which the data is to be aggregated include month or year.
Summary values can be displayed as Minimum, Maximum, any Quantil, and Standard Deviation.
Radial Diagrams
Plotted for individual samples as a method of graphically comparing the concentrations of measured parameters for several individual samples.
Shape formed by the Radial diagram identifies samples that have similar compositions and are particularly useful when used as map symbols to show the geographic location of different water facies.
Stiff Diagrams
Plotted for individual samples as a method of graphically comparing the concentration of selected anions and cations for several individual samples.
Shapes formed by the Stiff diagram identify samples that have similar compositions and are particularly useful when used as map symbols to show the geographic location of different water facies.
Pie Charts
Used to plot the concentrations ratio of the major ions (or any combination of parameters) for individual samples.
Used to graphically compare the concentration ratios of several measured parameters for several different samples.
Depth Profile Plot
Similar to a borehole log done in the field; the plot displays the change of a measured parameter over a measured sampling depth.
Can be used to plot all samples in the open database or selected sample groups.
Plotting over Georeferenced Raster Images
Sample locations can be displayed on an X-Y graph and detailed site maps can be imported from a variety of RASTER images such as JPG, BMP, TIF, etc. Overlaying your water quality plots over a georeferenced image will provide a familiar point of reference when you are analyzing sample data. In addition, the map plot can be used to display the location of different water types, or the symbols can be scaled in color or in size according to the concentration of a selected measured element.
Plotting over Vector Files
