Water Quality Data Analysis and Reporting Software
Aquachem is a groundwater software package specifically designed for anyone working with water data. This software is ideally suited for water projects requiring management, analysis and reporting of groundwater quality data.
AquaChem's analysis tools cover a wide range of functions and calculations used for analyzing, interpreting and comparing water quality data. These tools include simple unit transformations, charge balances, statistics and sample mixing to more complex functions such as correlation matrices and geothermometer calculations
These powerful analytical capabilities are complemented by an extensive selection of commonly used geochemical plots and graphs to represent the chemical characteristics water quality data.

Interactive GeoChemical Plots
AquaChem is capable of generating the following geochemical plots:
Correlation plots: Scatter, Ludwig-Langelier, Wilcox, Depth Profile
Summary plots: Box and Whisker, Frequency Histogram, Quantile, Detection Summary, Meteoric Water Line, Stacked Bars
Multiple parameter plots: Piper, Durov, Ternary, Schoeller
Time-series plots
Geothermometer and Giggenbach plot
Probability plots
Single sample plots: Radial, Stiff, and Pie
Thematic Map plots: Bubble, Pie, Radial and Stiff plots at sample locations
AquaChem allows you to create multiple plots for the same dataset and view these plots simultaneously side-by-side. All plots are interactive which means when you click on a data point, its corresponding sample is highlighted in the sample list. This is useful for identifying outliers.
Water Quality Data Analysis
AquaChem comes with a comprehensive calculators and converters that allow you to perform quick, on-the-fly analyses on your water quality data. AquaChem is capable of the following calculations and conversions:
Water type
Sum of Anions
Sum of Cations
TDS
Hardness
Alkalinity
Sodium Adsoprtion Ratio
Magnesium Hazard
Oxygen Saturation
Ion Balance
Common Ion Ratios
Scaling Indexes, such as Langlelier Index, Ryznar Stability Index, Puckorius Scaling Index and Larson Index
Water Quality Statistics
AquaChem includes a comprehensive list of statistical features, optimized to work with your water quality data. Statistical features included are:
Trend Analyses
Trend analysis estimates a potential positive or negative trend that may be present in your water data. The following trend tests are supported: Mann Kendall, Seasonal Mann Kendall, Sens's Test, Linear Regression, Spearman's Rank Correlation
Outlier Tests
Outlier tests identify outliers in your data - measurements that are extremely large or small relative to the rest of the data. The following outlier tests are supported: Extreme value test, Discordance test, Rosner test, Walsh Test
Alert Levels
Calculate upper tolerance levels for constituents to use as early warning indicators of potential violations of water quality standards. Methods available for calculating alert levels are probability, standard deviation x factor and tolerance interval
Summary Statistics
An automatic report that calculates basic statistics for a group of water samples. Statistics include minimum, maximum, range, interquartile range, arithmetic mean, standard deviation, non parametric quantile, confidence interval, skewness, kurtoisis and more.
Statistical analyses can be run for multiple samples and parameters simultaneously, and results can be easily plotted and exported to common file types (.xls, .csv and .mdb)
Automatic Reports
In just a few clicks, AquaChem delivers ready-made reports that contain key information about your water quality data. Report layouts can be fully customized using the Report Designer to accommodate specific project needs. The following automatic reports are supported:
Data Summary
Generates a summary for the AquaChem database and all stations and samples currently displayed in the sample list
Compare Sample
Compares a sample in your database to one or more samples
Mix Samples
Generates solution concentrations resulting from the step-wise mixing of specified proportions of two selected samples
Water Quality Standards
Provides a summary of parameters exceeding the established Water Quality Standards for the selected samples.
Hardness Dependent Standards
Provides a summary of parameters exceeding water quality criteria for metals
Rock Source Deduction
Provides a summary of the kind of minerals the water sample has been in contact with during its subsurface journey
Sample Summary Report
Provides a general overview of a single sample including major ions, hydrochemical facies, calculated hardness, ion balance, ion ratios, etc.
Thermometers
Lists the geochemical thermometers and their estimated temperatures
Isotopes
Lists the concentrations of isotopes 18O and 2H as well as infiltration temperature and height for 18O
Advanced GeoChemical Modeling
AquaChem links seamlessly with the popular geochemical modeling program, PHREEQC, 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 can link to the USGS programs PHREEQCI or PHREEQC for Windows, and you your AquaChem samples as input solutions for these modeling utilities.
