Day 2 DQO Training CourseModule 1 Introduction, Objectives, and Agenda Presenter: Sebastian Tindall 8:00 AM - 8:15 AM (30 minutes)
Introduction NAMP/EM-5 DQO Mission: • Make defensible decisions by managing uncertainty via systematic planning • Institutionalize the standardized Data Quality Objectives (DQO) Process (systematic planning) throughout the Department of Energy (DOE) complex
NAMP/EM-5 Courses To accomplish the mission, two courses have been developed: • Day 1- Managing Uncertainty for Environmental Decision Making • Overview of Systematic Planning with implementation approaches and tools • Audience - anyone • Day 2- Systematic Planning for Environmental Decision Making • ‘How to’ Implement the process • Audience - those who perform the DQO Process
Day 2 Course Objectives • Learn • “How to” for each activity in each of the 7 steps of the DQO Process • Basic statistical concepts using hands-on examples and computer simulations • How to manage uncertainty in the sampling and analysis design process • New Environmental Protection Agency (EPA) “TRIAD” approach for implementation of sampling
Systematic Planning Dynamic Work Plans Real-Time Measurement Technologies The TRIAD Approach
Important “How To” Concepts • Scoping is the most important activity • Poor scoping promotes distrust between regulators and facility managers • Using an independent facilitator who has technical knowledge promotes agreement between different opinions • Interviews with decision makers promote consensus and resolution of global issues
Important “How To” Concepts (cont.) • Global issues are those that do not require data to resolve but are crucial for success • Global issues are those that include interpretation of regulations • Resolution of global issues ensures technical staff resolve disagreements between decision makers prior to developing sampling designs • Good decisions require defensible sampling and analysis designs
Statistical Concepts • Generate frequency distributions • Transform numerical to graphical probability functions • Generate histograms • Evaluate error consequences versus target error rates • Evaluate error rates, number of samples, versus cost of analysis
How Many Samples do I Need? REMEMBER: HETEROGENEITY IS THE RULE!
Remember • Population is the TOTAL universe of objects within the decision unit • The only way to make decisions without errors is to take a CENSUS • Can’t sample or “measure” the ENTIRE site • Population must therefore be sampled representatively THUS
Uncertainty is additive!Analytical + Sub-sampling +Natural heterogeneity of the site=Total Uncertainty
Errors Are unavoidable!
Decision errors can be managed
How Many Samples do I Need? Sampling heterogeneity decreases as sampling density increases. REMEMBER:
To Control Sampling Error • Control sub-sampling methods and sample mixing methods • Take larger sample volumes • Reduce particle size • Specify methods that fit the sample size and particle size • Increase sample density by performing more on-site, rapid analyses
Deficiencies and Inconsistencies in Environmental Decision Making • Exist because an integrated decision-making process is not being used to make environmental decisions • Result from the lack of systematic planning • Result from failure to manage uncertainty • Result from lack of standard documentation • Result in decisions that are not scientifically, technically, or legally defensible • Result in vulnerability to third-party challenges
