1 st & 9 th Area Medical Laboratories Idaho National Laboratory Interagency Exercise September 2008
Agenda History AML Team Building Exercise Goals BROOM System Workflow Results Review
Interagency Players JPEO-CBD EPA DHS DoD NGB CSTs & HAZMAT teams Also involved in workgroup: - FBI - CDC - NIST
Area Medical Laboratory INL-1 (‘07) – Five personnel, 9 th AML, 4 th squad INL-2 (‘08) – 14 personnel – 9 th AML 4 th squad – lead – 9 th AML 3 rd squad – 1 st AML 4 th squad – 1 st AML 3 rd squad
Problem “How to prove that a room isn’t contaminated?” GAO Report – post attack analysis, GAO-05-493T cited lack of validated sampling plans Evaluation of sampling techniques and their efficacy in an operational environment
Test Plan Based on INL-1 small scale study – sampling strategies, efficiency of sampling methods, testing methods & validation of dispersal and sampling models – 5 test events Operational evaluation Reduce sample numbers without losing robustness Factors affecting detection minimums
Sample Receipt Logged into laboratory with the BROOM system
Building Restoration Operations Optimization Model - BROOM A decision support tool to collect, manage, and analyze sample data –Secure SQL Server database –GIS mapping & 3D visualization –Geostatistical analysis tools –Uncertainty analysis –Interfaces with VSP for statistical sampling design Data collection –Hand-held wireless PDAs with barcode readers and laser rangefinders –GPS for outdoors –Camera for photo documentation –Paperless data transfer –Secure transmission of data –Chain of custody report WITS – Where Is That Sample?

Results Wipe sampling is statistically more effective than vacuum or swab No statistical difference in effectiveness of recovery between sampling strategies in characterization RV-PCR vs. culture may be affected by repeat testing Onsite testing provided rapid feedback to incident commander
AAR AML successfully deployed/redeployed a tailored team of personnel and equipment Conducted ISO-9000 equivalent survey of operations Demonstrated laboratory contamination risk in operational situation Accurately tracked & reported 99.97% of ~3,000 samples
Review Reasons for INL-1 & 2 events Interagency operation 1 st & 9 th AML participation Processes Results
