Each week, the DQM Center emails the dredging Contractors/system providers a list of all data quality issues identified during a review of the previous weeks’ data. Comments are classified as “Investigate Further” (issues the DQM Center would like to have resolved along with an explanation of the issue or a plan of action for resolving the issue), “Advisory Items” (items that have been noticed but that the DQM Center does not feel are significant enough to warrant immediate action; such as one-off incidents or minor issues with “lower-importance” sensors which generally do not affect our ability to make dredge state determinations or perform data analysis), and “Acknowledged” (issues that have been previously identified and for which a plan of action or explanation has been provided by the contractor; these are listed until they are resolved or the planned timeframe for repair has elapsed, at which time they are moved back to “Investigate Further”).  These identified issues are also forwarded to the appropriate local District for awareness.

The DQM Center realizes that it can take time to resolve sensor issues (particularly with the ongoing COVID-19 pandemic). To account for this, any issues that have previously been identified and a plan of action or explanation has been provided by the contractor will be included under the "Acknowledged" tag until the issue is resolved or the planned timeframe for repair has elapsed. If the issue isn't resolved, then it'll be moved back to "Investigate Further".

Additionally, because much of the “state” data received from pipeline dredges is not available on the DQM Online Data Viewer, weekly summary reports of this data are generated and sent out to the local Districts to verify receipt of the information and to provide an easy way to view this data.
