Communicating Advanced Geophysical Classification to Stakeholders Herb Nelson Program Manager for Munitions Response SERDP & ESTCP 571-372-6400 herb.nelson@nrl.navy.mil
Outline ● Before the first engagement with stakeholders ● At the first planning meeting ● During the course of the project ● At the conclusion of the field work M2S2 Webinar - Communicating Classification to Stakeholders 2
Before You Meet with Stakeholders ● Develop a basic understanding of the technology � you don’t have to be able to solve the equations that describe the process � EMI data → intrinsic parameters → classification decision ● Make sure classification is appropriate to your site � this stuff is great and works most places but not everywhere ● Make sure you have a qualified contractor M2S2 Webinar - Communicating Classification to Stakeholders 3
Training Resources ● USACE Training ● ITRC “Tech Reg” Guidance Document & Internet-based Training ● ESTCP Training Resources M2S2 Webinar - Communicating Classification to Stakeholders 4
At the First Planning Meeting ● There is a big change here but it may not be what you think � we’ve always left metal in the ground � missed detections due to obstructions � anomalies below threshold � we just didn’t know much about that metal ● Using classification we know a lot about the items we leave in the ground � and we have put quality systems in place to prove it M2S2 Webinar - Communicating Classification to Stakeholders 5
At the First Planning Meeting ● Don’t exaggerate the capabilities of classification � it’s a really cool technology � there really are no silver bullets ● Seek buy-in on the remedial action objectives � defined and quantitative RAOs make classification much easier � should have been spelled out in the DD or ROD M2S2 Webinar - Communicating Classification to Stakeholders 6
At the First Planning Meeting ● Be ready with a thoughtfully-developed QAPP ● This is the cornerstone of the QC/QA process and should enable all team members to have confidence in the project results M2S2 Webinar - Communicating Classification to Stakeholders 7
During the Course of the Project ● Enforce the QC reporting schedule specified in the QAPP and make sure the QA Geophysicist stays up to date ● Stakeholder confidence is increased by � early identification of QC issues � careful and complete root cause analyses � prompt implementation of any required corrective actions M2S2 Webinar - Communicating Classification to Stakeholders 8
Example Project Documentation ● Surface Clearance Memo ● IVS Tech Memo ● Weekly QC Reports throughout the field work ● Anomaly Selection Tech Memo ● Intrusive Investigation Report ● Final Analysis Report and Justification for Stop Dig Point M2S2 Webinar - Communicating Classification to Stakeholders 9
Surface Clearance Memo ● Was everything found consistent with the CSM? ● Is there anything the analysts need to know? Evidence Found in CSM Surface Sweep 37-mm projectile Y 2.36-in rocket Y 60-mm mortar Y 75-mm projectile Y 81-mm mortar N 3-in stokes mortar Y Unexpected munition N M2S2 Webinar - Communicating Classification to Stakeholders 10
IVS Tech Memo ● Is the Sensor Functioning Properly and Ready to Collect Data? SLO Initial Dynamic IVS Seed Position 0.50 Accuracy 0.25 Y offset (m) IVS Seed 1 0.00 IVS Seed 2 -0.25 -0.50 X offset (m) -0.50 -0.25 0.00 0.25 0.50 M2S2 Webinar - Communicating Classification to Stakeholders 11
IVS Tech Memo ● Are the remedial objectives achievable? M2S2 Webinar - Communicating Classification to Stakeholders 12
Anomaly Selection Tech Memo ● Were all the blind seeds detected within spec? M2S2 Webinar - Communicating Classification to Stakeholders 13
Intrusive Investigation Report ● Were all recovered items consistent with analyst’s predictions? SW-30825 M2S2 Webinar - Communicating Classification to Stakeholders 14
Intrusive Investigation Report M2S2 Webinar - Communicating Classification to Stakeholders 15
What We Are Doing to Facilitate This ● Develop a set of standard QC and QA plots in UX ‑ Analyze ● Work hard at the QC interface between data collection and data analysis ● Make sure both of the above are in line with the evolving QAPP template M2S2 Webinar - Communicating Classification to Stakeholders 16
Verification and Validation ● Involve the stakeholders early and often in planning � draft plan before field work � final plans after contractor completes field work ● Verify the stop-dig threshold � dig past the last TOI M2S2 Webinar - Communicating Classification to Stakeholders 17
Contractor Stop Dig Threshold 23 digs past the last TOI M2S2 Webinar - Communicating Classification to Stakeholders 18
Verify The Threshold 200 digs past the last TOI M2S2 Webinar - Communicating Classification to Stakeholders 19
Verification and Validation ● Involve the stakeholders early and often in planning � draft plan before field work � final plans after contractor completes field work ● Verify the stop-dig threshold � dig past the last TOI ● Validate the whole process � targeted investigation of items classified as likely clutter M2S2 Webinar - Communicating Classification to Stakeholders 20
Validate the Process 100 randomly selected 200 digs past the last TOI M2S2 Webinar - Communicating Classification to Stakeholders 21
Verification and Validation ● Involve the stakeholders early and often in planning � draft plan before field work � final plans after contractor completes field work ● Verify the stop-dig threshold � dig past the last TOI ● Validate the whole process � targeted investigation of items classified as likely clutter M2S2 Webinar - Communicating Classification to Stakeholders 22
