Waterloo Hydrogeologic, a division of Nova Metrix LLC , has released AquaChem 14.0, the latest version of our industry-leading software for those working on hydrogeologic, geochemical, or environmental projects requiring the management, analysis, and reporting of water quality data.
For this release, we have made it easier to filter for samples in the AquaChem project database, added powerful new tools for identifying trends in time series data, made improvements to plots, among other improvements and fixes. AquaChem’s analysis tools cover a wide range of functions and calculations used for analyzing, interpreting and comparing water quality data, including unit transformations, charge balances, statistics, and geochemical modeling using PHREEQC. These powerful analytical capabilities are complemented by an extensive selection of geochemical plots to represent the chemical characteristics of water quality data and a console for R-scripts that offers powerful data science tools.
Trend Analysis Module
The new Trend Analysis module has been added, allowing you to perform statistical analyses on time series data.
– Tests and analyses supported:
. Linear regression
. Sen’s slope estimator
. Spearman rank correlation
. Mann-Kendall test
. Seasonal Mann-Kendall test
– Trend analyses may be exported as spreadsheets or automatically plotted in time series graphs
Improved Sample Set Editor
The Sample Set Editor has received a major upgrade in functionality, allowing you to filter your data in a more powerful and precise manner.
– OR statements: Sample set conditions may now be connected with the OR logical operator
– Group conditions: conditions in the sample set editor can now be grouped
– Qualifier field: sample sets can now be conditioned on the qualifier field of the sample result, allowing for non-detects to be easily extracted or excluded
– New conditions: The new parameter conditions “Does not equal,” “Has value,” and “Has no value” have been added
Plotting
Plots have received numerous upgrades
– Linear regression lines: Linear regression lines may now be automatically calculated and plotted on Scatter and Time Series plots in the Lines tab
– Faster symbology changing: The applied symbol group can now be changed directly in the plot settings in the new Symbols tab
– Labeled lines: Lines can be given arbitrary labels or take label data from calculated linear regression lines
– Configurable legend locations: The location of the legend can now be customized
– Box-and-Whisker plot improvements: Box-and-Whisker diagrams can now be labeled with the number of samples and non-detects for each data series
Usability
– Water quality standards may now be exported
– Modeled and Calculated parameter results may now be exported from the Sample Report module
– Sample analysis result metadata (such as precision, result comments, etc.) may now be exported from the Sample Report module
– The Sample Analysis Viewer module is now sortable
– Newly-created parameters can now be updated from the Parameter Calculator by default
– Defining DateTime data values in tables and in the Sample Set Editor is now easier
– Durov/Piper diagram titles no longer list all parameters by default
AquaChem is a groundwater software package specifically designed for anyone working on environmental projects requiring management, analysis, and reporting of water quality data. 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 representing the chemical characteristics of water quality data and a console for R scripts that offers powerful data science tools.
This video is very quick and useful for beginners to start aqua chem rapidly. It contains how to know hydrogeochemical and bacteriological analysis of a given ground water samples.
Waterloo Hydrogeologic Inc. was founded in 1989. The company’s line of business includes providing computer programming services. Woburn, MA March 13, 2015 – Nova Metrix LLC (“Nova Metrix”) is pleased to announce the acquisition of Schlumberger Water Services Technology Group, which is comprised of Van Essen Instruments (Diver Brand), Westbay Instruments, and Waterloo Hydrogeologic, which were formerly part of the water monitoring division of Schlumberger Water Services. Waterloo Hydrogeologic (currently operates under the legal name Nova Metrix Ground Monitoring (Canada), Ltd. Waterloo Hydrogeologic Division) continues to develop new programs to meet the advancing needs and technology requirements of the groundwater industry. We now offer four main software packages; Visual MODFLOW Flex, Hydro GeoAnalyst, AquaChem, and AquiferTest.
