Starting a DQM Event
Copyright © 2019 EarthSoft, Inc • Modified: 12 Nov 2019
The first step in the DQM data qualification process is to start a DQM event. For each DQM event, the analytical data sets requiring qualification and the DQM QAPP specific checks must be selected. During the Start Event step, the automated checks for the selected DQM QAPP are run and DQM adds several new columns to the Analytical Results output table, including DQM_QUALIFIER, DQM_REMARK, APPLY_QUALIFIER and APPLY_REMARK. When DQM discovers an exception to a DQM rule, both QUALIFIER columns are populated with that rule's qualifier. The DQM_QUALIFIER and DQM_REMARK columns are not editable; this is to preserve the records of the DQM suggested qualifiers.
Once the DQM event is started, the review continues with Processing a DQM Event (the next step in the DQM data qualification process).
Click the DQM Start Event button on the Data tab. This will open the DQM - Start Event Form.
From the DQM Selections tab click the QAPP drop-down to select the DQM_QAPP_CODE group to run checks from.
Click the Check box(es) to select one or more checks to run.
or click the Select All check box and run all checks or deselect some checks.
If Holding Time (HT) is one of the selected DQM checks, then the Holding Time Types must also be selected from the list to the right of the checks.
Select the Dataset Selections tab. Chose the analytical results for qualification by Selection Type. The following types are available:
•Chain of Custody
•Test Batch IDs
Select the desired option(s) from the Selection Type list. When one of the radio buttons is selected, all available data sets pertaining to that option will display in the selection pane.
Click the check boxes for all the data sets that are needed for the data qualification event. The Filter button on any column header can be used to find the desired data set(s).
As analytical data sets are selected, their identifiers will appear in the Dataset Selections summary box on the right side of the form. This provides a summary of all the analytical results input selections.
At least one data set must be selected from the list to start a DQM event. Multiple data sets of each type can be selected. Data sets from different types can be incorporated into the same DQM event.
Note: Unlike most other EQuIS reports and excluding the MAGs type, these selections are additive. Therefore, when multiple selections are made, the DQM event will include samples that have one or another of the selections, not just the samples that have all of them (The optional MAGs input behaves in the typical EQuIS report selection manner of excluding all results that are not in the specified Method Analyte Group).
If desired, check the Only return Unvalidated Results check box to restrict the event to results with DT_RESULT.VALIDATED_YN = 'N'.
Optionally, check the Include Field Quality Comments check box to add a Field Quality Comment column to the Review Samples > SAMPLES table output, and populates it from DT_SAMPLE_PARAMETER.PARAM_VALUE where PARAM_CODE = FieldQualityComment. (These DT_SAMPLE_PARAMETER records are created by EDGE when a Field Quality Comment is added during field data collection).
Select the Selection Summary tab and review selections.
Click the Start Event button to start the DQM Event. When the qualification finishes, the DQM Event Review form opens to allow the user to Process a DQM Event.
