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
  • Methods Detection Capability
  • Methods 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
