  1. SPADAT Program and Visual Sample Plan (VSP) Update Pacific Northwest National Laboratory (PNNL) Brent Pulsipher, John Wilson, Lisa Newburn, Landon Sego, J. Hathaway, Brett Matzke, Chris Murray, Scott Dowson, Nancy Hassig, Ryan Orr.

  2. Outline Why Systematic Planning and Data Assessment Tools and Training (SPADAT) Program? VSP Refresher Past and Planned VSP Training New DOE Sponsored Methods and Features VSP 6.0 (QA, Testing, Users Manual) Radiological Survey Design and Analysis Sequential and Stratified Design/Analysis Modules Updated Confidence Interval Data Analysis Change old user dialogs to sentence structure input Multiple Increment sampling for Hotspots: Methodology Several User Requested Changes/Additions Leveraging off Other Agency Investments Life after VSP 6.0

  3. Why SPADAT Program? All DOE Sites Obtain Samples for Variety of Purposes Decommissioning and Decontamination Environmental Characterization and Remediation Environmental Monitoring (in process and long term) Process/Quality Control and Health Monitoring SPADAT Exists To: Ensure There are Methods/Tools for Gathering the Right Type, Quality, and Quantity of Data to Support Confident Decisions Facilitate Statistically Defensible Data Analyses Provide Training on Available Tools Decreased Costs, Increase Defensibility While Managing Uncertainty

  4. What is Visual Sample Plan (VSP)? Data Quality Objectives (DQO) based systematic planning software Determines the number and location of samples/transects Ensures confident, statistically defensible decisions Performs statistical and data quality assessment in support of decision making process. Sponsored by DHS, DOE, EPA, DoD, UK, CDC Free VSP Download at http://vsp.pnl.gov/ >5000 Users

  5. Current VSP Applications Identification, Delineation, and Remediation of UXO Sites Within-Building Bio/Chem/Rad Terrorist Event Environmental Remediation Decontamination and Decommissioning Long-Term Legacy and Groundwater Monitoring Natural Disaster Assessments (Katrina) Outdoor Bio/Chem/Rad Terrorist Event Item audits and surveillance. Wherever Sampling Is Used to Support Decisions

  6. VSP Screen Shot Maps, Photos, Images, Floorplans can be imported/exported with sample areas defined and samples displayed. Diagnostic interactive graphics can be manipulated to quickly see effects on design of changing DQO inputs Detailed 3-15+ page report automatically generated documenting design, assumptions, maps, equations, DQOs, analyses Sample location coordinates listed and available for output for use in the field (w/GPS) 6

  7. DOE-HS VSP Objectives • Must Be Useful for DOE Sites • Decrease Costs • Increase Defensibility • Directly Applicable to DOE Site Issues • Be Practical • Easy to Use • Facilitated Technology Transfer • Many of the SPADAT tasks are focused on making VSP more easily applied in the real world and expanding the methods and tools to address complications that are always present in the real world. 7

  8. VSP Training Courses 3.5 Day Format 2 Days of General Training 1.5 Days of Advanced Training Completed during FY10: DOE Grand Junction Nov 3-4, 2009 DOE and EPA at ANL Jan 19-22, 2010 DOE and EPA at LLNL June 8-11, 2010 Hanford CHPRC (soil/groundwater focus) July 12-13, 2010 Hanford CHPRC (Radcon focus) Aug 30-31, 2010 5 other DoD /UK/NRC Courses Upcoming: 2-4 DOE (Paducah, SRS, Vegas, KC Plant) Winter/Spring FY11 NRC (DC & Chatanooga) Oct/March FY11 DoD UXO Courses– San Antonio & Denver Oct & Feb Currently Seeking Cost Sharing Funding for DOE courses

  9. VSP 6.0 Release • Culmination of many new methods and features • Extensive QA Testing • Identified/Resolved >250 issues • Formal bug tracking software employed • Two month, 9 person effort • Updated all online help, automatically generated reports, Users Manual • Issued June 4, 2010 9

  10. Radiological Survey Design and Analysis • Transect design to have high prob. of detecting hot areas • Flag potential hot areas • Create interpolated map identifying hot areas (kriging) • Delineate hot areas and explore characteristics 10

  11. Sequential Sampling Updated • Previous module created in version 2.0 • Very user-un-friendly • Completely revamped data entry features • Created new interface • Sentence style user dialog • Updated help and automatically generated reports 11

  12. Sentence Style User Dialogs Before After 12

  13. Multiple Increment Hotspot Sampling • MI Sampling is great for mean estimation but loses spatial info • DQO method developed for determining the number of rows/columns and MI samples needed to detect/locate elevated hotspot(s) • Example shows 32 analyses vs 256; Ability to locate hotspot retained • Journal publication submitted; VSP Implementation pending 13

  14. Confidence Interval Data Analysis • Previous versions had sampling design for confidence interval objective but no data analysis capability • Added one and two sided confidence interval calculation • Both parametric and non-parametric confidence intervals and recommendation based on normality test 14

  15. Other User Requested Improvements Google Earth Image Import/Calibration Quasi-Random Sample Placement set as default Allow systematic sampling for X%/Y% based sample designs Put actual and calculated “n” on user dialogs for grid/hotspot modules Resolve data entry options when existing sample design locations are present

  16. Leveraging Off Other Agency Investments Map/Building Layer Control (DHS, EPA) Tool Integration- BROOM, Scribe, GeoSoft (DHS,DoD) Data Entry System (DHS) Improved CJR Sampling Algorithm (DHS) Menu Restructuring (DHS) Optimal Addition of Well/Spatial Sample (DOE-LM) Target/Hotspot Area Delineation (DoD) VSP 6.0 QA, Online Help, Report Generators (DHS, DoD) Training Course Case Studies (UK-AMEC, Hanford) Many More…. DOE Gets Much Bigger Bang for Buck!

  17. Live Demo of Certain Features and Sneak Preview of 6.1 Features(as time allows) • Menu Restructuring • Layer Control and Multiple Floors • Data Entry • Spatial Sample Addition • 3-D Maneuvering • Furniture Construction, Library, and Placement • Sample Area and Image Transparency • Building Set-up from Image 17

  18. What’s On the Horizon? • Real-Time Effluent Monitoring Control Charts • QA Checker • Building Setup and Furniture Improvements • Hotspot Delineation and Remediation Cost Calculator • Stratified Sampling Within Building Procedures • MI Sampling for Hotspots • Better Handling of Multiple Analytes and Support for Multiple Analyte Decisions • Piles and Subsurface Volume 3-D Sampling • Expert Mentor for Buildings • Many Other items on Wishlist • VSP 6.1 in Early CY11 18

  19. Continued Appreciation A Huge Thanks to George Detsis for his continued leadership and support!
