MARLAP Manual: Multi-Agency Radiological Laboratory Analytical Protocols

MARLAP is a comprehensive guidance manual for project planners, managers, and radioanalytical laboratories. It aims to improve data quality, reduce repeated analyses, and bolster public confidence. The manual covers key analytical planning issues and provides a framework for linking project planning, implementation, and assessment. It supports various data collection activities such as site cleanup, environmental monitoring, and waste management. The manual outlines data quality objectives and measurement quality objectives and includes a structured approach to method evaluation and performance demonstration. MARLAP also offers guidance on laboratory services, waste management, and measurement statistics.

  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
