Sample List

The Sample List tab provides an overview of the samples in the selected Sample Set or Station Group. This tab displays fields from the Sample table (left) and also displays results for the active sample, as denoted by the symbol in the sample table (right). Results in the Sample Results pane are shown by parameter type in the tab at the top of the results pane:

Measured parameters are those values that are explicitly stored in the database and typically have been measured either in the field or in an analytical laboratory. Results with values that exceed an active Water Quality Standard will be color coded. The list of measured parameters can be limited to a selected parameter group.


Calculated parameters are those values that have been calculated using the built-in functions available in Hydro GeoAnalyst Plus.  These are calculated dynamically and are not stored in the database.


Modeled parameters are those values that have been estimated using PHREEQC.



Note that results with values that exceed an active Water Quality Standard will be color coded.



The Sample table and results viewer toolbars in the Sample List tab contain the following controls:


Sample Table Toolbar


Sample Results Toolbar - Measured


Sample Results Toolbar - Calculated


Modeled Sample Results Toolbar



Navigates data pages; skipping to the first page (in the sort order), to the previous page, to the specified page, to the next page or to the last page.

 Adds a new record (i.e. sample or result) to the appropriate table.

 Deletes the currently selected record(s) from the project database.

Saves the changes you have made to the project database.

Refreshes the data from the project database and undoes any unsaved changes.

Allows you to select which columns you want to show or hide in the sample table.

Toggles the width of the table either stretch to fit the view or allow a horizontal scrollbar.

Exports the data from the applicable table to an unformatted Excel file.

Exports the table to a selected Excel workbook based on a selected template.

Calculates the water type for the selected record(s).

Calculates the water type for all records in the sample list.

Splits the sample table and results viewer horizontally.

Splits the sample table and results viewer vertically.

Provides the option to display concentration results using a single/consistent unit for all applicable parameters in the results viewer.

Provides the option to display the active water quality standards.

Allows you to filter displayed results to the selected parameter group.

Opens the calculation settings.

Calculates the saturation indices and (log) activities for the active sample based on the current default thermodynamic database using PHREEQC.


Working with the Data

The first line shown on the sample table in the Sample List Tab contains field names/column headers; below this is the filter line, which is highlighted in light blue and denoted by the clear filter button () in the left-most column. The filter line can be used to restrict records to display based on the values in one or more field and is described in detail in the Data Filtering section.

You can select one or more records (that will turn bright blue) in the data table by clicking on the buttons on the left-hand side of the grid (using the <SHIFT> and <CRTL> keys for selecting multiple records). You can perform the several actions by right-clicking on the selected record(s) in the currently displayed table, including showing/hiding fields and records, copy, paste, adding the selected station(s) to a new/existing station group, refreshing the data from the project database, and resizing the columns to fit the station list table within the current workspace.

Values in the data fields may be modified for a selected sample (simply click in the cell you wish to edit); or a new sample may be created here (selecting the icon), and the values for these fields may be defined. The Sample List tab may be used to quickly enter numerous samples and their results.
