  1. Multi-Agency Radiological Laboratory Analytical Protocols Manual: MARLAP Presentation to the Radiation Advisory Committee/Science Advisory Board April 23, 2002 Presenter: John Griggs U.S. EPA

  2. Description of MARLAP • A multi-agency guidance manual for project planners and managers and radioanalytical laboratories • Participants include: EPA, DOE, NRC, DOD, NIST, • USGS, FDA, Commonwealth of Kentucky, State of California

  3. Consequences of Current Lack of Guidance • Existing data frequently not adequate for decision making • Increased likelihood of repeated analyses and additional cost • Potential erosion of public confidence in work performed at sites

  4. Goal of MARLAP • Ultimate goal of MARLAP is to provide guidance and a framework: • to assure that laboratory radioanalytical data meet a program's or project's specific needs and requirements

  5. MARLAP Objectives • Providing a framework and an information resource for using a performance-based approach for radioanalytical laboratory work • Promoting a directed planning process involving radioanalytical laboratory expertise • Providing guidance on how to link project planning, implementation and assessment from an analytical perspective

  6. MARLAP Objectives (cont'd) • Making collective knowledge and experience in radioanalytical laboratory work widely available • Providing guidance on obtaining and evaluating laboratory services

  7. MARLAP • Written for project managers and planners and radioanalytical laboratory personnel • Consistent with relevant guidance such as ISO, ANSI, ASTM, and agency documents • Performance-based approach instead of a prescribed approach

  8. Data Collection Activities Which MARLAP Supports • Cleanup of Contaminated Sites • Environmental Monitoring • Waste Management • Site Characterization • Post-Accident Response • Background Studies

  9. DQOs and MQOs • Data Quality Objectives (DQOs) • Outputs of a directed planning process • Address sampling and analytical uncertainties • Measurement Quality Objectives (MQOs) • Project-specific requirement for select analytical parameters (e.g., method uncertainty, detection limit) • Analytical portion of the DQOs

  10. MQOs • Example Analytical Parameters • Method Uncertainty • Method’s Detection Capability • Method’s Quantification Capability • Example MQO • A standard uncertainty of 0.10 pCi/g or less is required at the action level of 1.0 pCi/g

  11. Role of MQOs • Method selection and evaluation • Criteria for method selection • Basis for method performance demonstration • Ongoing data and performance evaluation • Criteria for QC and PE samples • Criteria for select sample parameters (e.g., measurement uncertainty) • Final data evaluation • Criteria for data validation • Analytical criteria for data quality assessment (DQA)

  12. Deriving MQOs from DQOs • Key inputs to the process • Action level • Gray region • Information on matrix and analyte • Establishing MQOS – MARLAP provides: • Mathematical framework • General rules and recommendations

  13. Manual Outline • Part 1 • Ch.1 Introduction • Ch.2 Project Planning Process • Ch.3 Key Analytical Planning Issues • Ch.4 Project Plan Documents • Ch.5 Obtaining Laboratory Services • Ch.6 Selection and Application of an Analytical Method • Ch.7 Evaluating Methods and Laboratories • Ch.8 Radiochemical Data Verification and Validation • Ch.9 Data Quality Assessment

  14. Manual Outline • Part2 • Ch.10 Field and Sampling Issues • Ch.11 Sample Receipt, Inspection and Tracking • Ch.12 Laboratory Sample Preparation • Ch.13 Sample Dissolution • Ch.14 Separation Techniques • Ch.15 Nuclear Counting Instrumentation • Ch.16 Instrument Calibration and Source Preparation • Ch.17 Data Acquisition, Reduction and Reporting • Ch.18 Laboratory Quality Control • Ch.19 Measurement Statistics • Ch.20 Laboratory Waste Management

  15. Manual Review Schedule • Internal federal/state February-July 2000 • agency reviews completed • Manual was revised based July 2001 • on 2,000+ review comments • Available for peer and Currently underway • public review

  16. Next Steps • Revise manual based on public and peer review comments • Develop an Executive Summary – “MARLAP Roadmap” • Finalize glossary • Develop implementation tools • Training courses • Software programs • Detailed example scenarios
