AquaChem

Water Quality Data Analysis and Reporting Software

AquaChem’s analysis tools cover a range of functions and calculations including unit transformations, charge balances, and statistics. These powerful analytical capabilities are complemented by an extensive selection of commonly used geochemical plots to represent the chemical characteristics of water quality data.

What's New in AquaChem 15.0

Import improvements

Importing data is now easier than ever:

  • Smart mapping: Source data column names can now be automatically mapped to project fields using fuzzy (inexact) matching
  • Chemical list import: Matched chemical parameters can now be imported from the master chemical database with just one

QC reports

The brand-new QC report module has been added, allowing out-of-the-box capability to detect and report common quality control issues in sample data.

  • Define parameter holding times: Chemical parameters can now have holding times defined, allowing for sampling violations to be automatically documented
  • Instant sample summaries: Easily report summary data, major ion composition, parameters which exceeded the maximum holding time, measurements below the MDL, and parameters outside of their defined natural occurrence range
  • Reliability tests: Flag samples with unacceptable calculated electroneutrality, TDS-to-conductivity ratios, major ion ratios, and more
  • Fully configurable: The contents of the QC report are fully configurable, allowing you to enable and disable report sections, add parameters, and set the attention level for the reliability tests

Bulk data import

Multiple data sources can now be imported at once using the same mapping

  • General bulk import: Simultaneously import many spreadsheets of data that have the same formatting, such as sample data or station data
  • Robust processing: Bulk import smartly rejects incompatible and incorrectly formatted data, speeding up data management workflows and simplifying QA/QC

Usability

  • Data associated with stations can now be compared and moved/copied between stations using the new Compare tool
  • Lists in the List Editor module can now be filtered (like other tables can)
  • Improved interface for assigning values to DateTime data in tables

Interactive GeoChemical and Statistical Plots

AquaChem allows you to create multiple plots for the same dataset and view these plots simultaneously side-by-side. All plots are interactive – click on a data point and its corresponding sample is highlighted in the sample list. This is useful for identifying outliers.

  • 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, Pie, Stacked Bars, Radial, Time Series
