The following list provides answers to some of the most common problems encountered by users of AquaChem 2014. Please review this list of Frequently Asked Questions before contacting Technical Support for assistance with your project.

If you have a question that isn’t listed here, please contact our technical support team support@waterloohydrogeologic.com

  1. Check that you have assigned symbols to that sample(s) using the Symbol Editor.
  2. Ensure that you have entered data for each parameter required by that plot.
  1. Check that you have defined a symbol for the sample(s) using the Symbol Editor.  The “unexpected” symbol you are seeing may be the default symbol.
  2. Check which samples are selected in the Sample Picker. Selected symbols will be shown based on the Active Symbol style settings. Samples which are selected in the sample picker or sample list will be shown using a light blue color () by default.

This can be corrected by modifying the parameter format. Open the Parameter Editor, select the appropriate measured parameter using the parameter picker, and modify the “Display format” to set the number of decimal places to the desired value.

Station groups created based on a dynamic sample set contain all of the samples from stations associated with that sample set. Therefore, the sample set associated with a station group will typically contain more samples than what you find in the actual sample set itself. This may be useful in evaluating trends at stations meeting some criteria such as exceedances.

The modeled tab is only present in the Sample Results pane for samples imported from AquaChem 2014 projects that include PHREEQC results. New samples created in or imported into AquaChem version 9 will not include the Modeled tab. Support for PHREEQC in newer versions of AquaChem is under development and will be available in an upcoming release.

  1.  Parameters required for the calculation have not been mapped. Select Project > Properties from the main menu and review the Parameters tab. If a required parameter has not been mapped then AquaChem doesn’t know what values to use in the calculation.
  2. No result is available for one or more of the input parameters required for the calculation. If you do not collect the data required for a particular calculation you can simply hide that calculated value from the Calculated data tab by clicking the Properties button in the toolbar and hiding the calculations that you don’t need.

Yes! In AquaChem you can define multiple Piper plots (or any other plot type) in one or more plot collections and define the source data for each plot based on one or more different data sources (e.g. Station Groups or Sample Sets).

Make sure that you activate a sample set that contains the missing data. If you have activated a static or dynamic sample set that does not capture the newly imported samples then they will not be displayed in the Sample List. To display all samples double-click the ‘All Stations’ sample group in the Project Tree. This will display all samples from the entire project within the Sample List.

If you cannot install packages in R using the install.packages() command; please follow the Installing R instructions. Conversely, you can try installing R in a local folder that does not require administrative privileges and pointing AquaChem to this installation location using the R-Console settings.

The R-Console output window has been streamlined to only output results using the print() command to improve script runtimes and reduce output clutter.

Be sure to add a “+” at the beginning of each continued line. R-Console in AquaChem interprets R on a line-by-line basis and unlike RStudio and RGui, you must explicitly continue multi-line commands.

Yes. Both versions of AquaChem will run on the same computer provided the system requirements are met for each.
