  1. Day 2 DQO Training CourseModule 8 Closing Remarks Presenter: Sebastian Tindall (10 minutes)

  2. Module 8Closing Remarks & Final Exam Objectives: • To summarize key points made today • To answer the “How many samples” question • “Final Exam” • Questions/feedback from the audience

  3. The DQO Process • “A systematic planning process based on the scientific method for the unambiguous defining of • Environmental decision criteria • Data requirements • Error tolerances • and the documentation / preservation of these details in a consistent, standardized format providing a defensible record of the decision” Merrick “Rick” Blancq US Army Corps of Engineers Portland District Merrick.P.Blancq@nwp01.usace.army.mil

  4. Systematic Planning Doesn’t Just “Happen” • Haphazard approaches yield haphazard results • Decision makers must provide input early & often • Need an implementation process • Successful implementation model evolved as the DQO Process was used

  5. Tools Make the Job Easier • Scoping Checklist • DQO e-Workbook (electronic template) • Standardized DQO Report format • DQO Web Site • DQO tools and materials • Latest version of all of today’s slides • Visual Sample Plan (VSP) • Download free software • Data Quality Assessment tools (coming!)

  6. Managing Uncertainty • We are forced to make environmental decisions based on estimates • Estimates always involve errors • Errors in estimates are not mistakes • If unmanaged, errors in estimates CAN lead to Decision Errors which ARE MISTAKES • Decision Errors must be managed • Identify • Quantify • Severe consequences of decision errors mandate a statistical basis

  7. Defensibility • Comes from doing good science • Requires documentation • “If it isn’t written down, it didn’t happen” • Use a standardized format • We must employ the scientific method to make defensible decisions

  8. How Many Samples do I Need? REMEMBER: HETEROGENEITY IS THE RULE!

  9. Begin With the End in Mind DATA Contaminant Concentrations in the Spatial Distribution of the Population Population Frequency Distribution Correct Equation for n (Statistical Method) , , ,  Alternative Sample Designs Optimal Sampling Design How many samples do I need? The end

  10. Logic to Assess Distribution and Calculate Number of Samples

  11. A Visual Decision Strategy

  12. Must contain a clear presentation of (and the reasoning behind): Project Planning Documents • DQO Report • FSP • Quality Assurance Project Plan • HSP • Work Plan

  13. Project Planning Documents • More detailed, technical project goals/decision rules (DQOs), that will guide project decision-making • Goals for data quality (MQOs) • How sampling representativeness will be ensured, and how sampling uncertainty will be controlled • List of analytical technologies and methods • QC protocols and criteria to demonstrate that data of known quality will be generated • Description how data will be assessed and interpreted according to the decision rules • General project decision goals

  14. Uncertainty is Additive! Analytical + Sub-sampling +Natural heterogeneity of the site=Total Uncertainty Remember the uncertainty is additive for all steps in sampling and analysis

  15. Do it! (Get the job done - right) Site Closed Prove it! (Document what/why/how) Keys to success • Sound technical basis • Complete and thorough documentation
