AquaChem

Management Software for Water Quality and Groundwater Sampling Data

  • Data handling and analyzing, geochemical diagrams
  • Statistical computing
  • Water quality modelling (PHREEQC)

 

Overview

AquaChem is ideal for groundwater and surface water projects requiring management, analysis, plotting, and reporting of water quality data. AquaChem features a fully customizable database of physical and chemical parameters and a comprehensive selection of analysis, calculation, modeling, and graphing tools.

AquaChem's analysis capabilities cover a wide range of functions and calculations frequently used for analyzing, interpreting, and comparing water quality data. Efficiently analyze trends for tens or hundreds of samples and parameters in minutes, with confidence. These powerful analytical capabilities are complemented by a comprehensive selection of commonly used plotting techniques to represent the chemical characteristics of aqueous geochemical and water quality data.

For in-depth geochemical modeling, AquaChem provides powerful geochemical reaction modeling capabilities using the USGS engine PHREEQC.

Features

Data Management

  • Built around a customizable MS Access database that can be configured to include more than 1000 alphanumeric parameters per sample.
  • Parameters are divided into the following parameter groups: station description parameters, sample description parameters, measured parameters, and modeled parameters.
  • Each parameter group contains predefined parameters which can be used to create a customized data structure for your sampling and reporting requirements.
  • Data may be imported and exported in various formats including MS Access, MS Excel and .TXT files.

Data Analysis

  • AquaChem uses the common measured values (cations and anions) for each sample to calculate additional geochemical values including water type, sum of Anions, sum of Cations, Ion Balance, TDS, hardness, Alkalinity, Common Ion Ratios, Sodium Adsorption Ratio, Magnesium Hazard, Oxygen saturation and Scaling Indexes such as Langlelier Index, Ryznar Stability Index, Puckorius Scaling Index and Larson-Skold Index.
  • Data Analysis features include: Compare Samples, Correlation Matrix, Water Quality samples, Mix Samples, Data Reliability check, Rock Source Deduction.

Statistical Calculations

  • AquaChem includes a comprehensive list of statistical features, optimized to work with your water quality data set. Statistical features included with this software are: Trend analysis (Mann Kendall, Sen's Test), Outlier Tests (Extreme value, Discordance, Rosner, Walsh test), Test For Normality (Studentized range test, Geary's, Shapiro, D'Agostino test).

Water Quality Modeling

  • PHREEQC generated values (saturation indicies, activities) can be read back to the database and used for reporting, plotting or statistics.
  • PHREEQC generated values (saturation indicies, activities) can be read back to the database and used for reporting, plotting or statistics.

Plotting, Mapping & Reporting

  • Includes a comprehensive selection of more than 23 industry-standard plots including: Piper, Schoeller, Scatter, Box & Whisker, time series, histogram, Stiff, Radial and Pie chart.
  • AquaChem offers a unique way to interact with graphics and allows for quick identification of points on plots
