AquaChem is a software package developed specifically for managing, analyzing, and plotting water quality data. It features a fully customizable database of physical and chemical parameters and provides a comprehensive selection of analysis tools, calculations, and plots for interpreting water quality data.
AquaChem provides a wide range of functionalities and calculations including unit conversions, charge balances, sample comparison, statistical summaries, and much more. AquaChem also contains a customizable database of water quality standards with support for multiple action levels for each parameter. Any samples exceeding the selected standard(s) are automatically highlighted with the appropriate action level color for easily identifying and qualifying potential problems.
These powerful analytical capabilities are complemented by a comprehensive selection of commonly used plotting techniques to represent the chemical characteristics of water quality data. The plot types available in AquaChem include:
•Geochemical Plots: Piper, Stiff, Durov, Schoeller, Wilcox, Giggenbach, Meteoric Water Line, Ludwig-Langelier, Ternary;
•Statistical Plots: Box and Whisker, Histogram, Probability, Quantile, Detection Summary
•General Plots: Scatter, Line, Pie, Stacked Bars, Radial, Time Series; and
•Map Plots: Uniform Symbols, Proportional Symbols, and any of the above plot types can be added to a map based on the location of the data
Each of these plots facilitate interpretation of the many complex interactions between groundwater and aquifer materials and help you identify important data trends and groupings.
In addition, AquaChem features a built-in link to PHREEQC, the popular geochemical modeling program developed by the USGS, for calculating equilibrium concentrations (or activities) of chemical species in solution and saturation indices of solid phases in equilibrium with a solution. For more advanced simulations, you may link to the USGS programs PHREEQCI or PHREEQC for Windows, and use your AquaChem samples as input solutions for these modeling utilities.
AquaChem also contains a console for the R scripting language that puts the vast set of R libraries for statistical analysis, visualization, classification, clustering, modeling, and more at your fingertips. Save and load scripts within R to automate working with your data. Note that R and its libraries must be downloaded separately and is available through the Comprehensive R Archive Network (CRAN) which can be found on the main R website.
Once you start using AquaChem, you will see that it is truly one of the most powerful tools available for managing and interpreting any water quality data set.
