The Oak Ridge Sample Management Office (SMO) provides a cost-effective, performance-based approach for the procurement of analytical laboratory and data quality services for DOE Oak Ridge Operations (ORO).
Oak Ridge Sample Management Office Mission
In May 1996, DOE EM issued a policy requiring the establishment of a single sample management office at each DOE field operations office. This policy eliminated the duplication of effort associated with the awarding and management of contracts, which resulted in the inefficient use of DOE laboratory resources.
Based upon this policy, the SMO mission and objectives are:
- Procure analytical services based upon a best-value added determination and free from any financial interests related to the contracting decision.
- Review sample management activities to assure quality and the cost-effective provision of analytical services.
- Maintain a list of qualified full-service and specialty laboratories that can be used by DOE
Oak Ridge contractors.
- Establish the routine use of Data Quality Objectives (DQO) processes in planning sampling
and analysis activities and effective participation in a national characterization quality assurance program.
- Provide data verification and validation services to projects and programs associated with
Oak Ridge Reservation activities.
The Oak Ridge Sample Management Office utilizes a suite of qualified, full-service and specialty laboratories whose performance are monitored, evaluated, and compared by the Integrated Performance Indicator Program (IPIP). These laboratories are reviewed under the Department of Energy Consolidated Audit Program (DOECAP).
Double-Blind Performance Evaluation
Double-blind performance evaluation (PE) samples are introduced into field sampling batches. Samples are introduced in a manner whereby the contract analytical laboratory is unaware of either the nature of the sample (i.e., a PE sample) or of its component concentrations, thus preventing “special” treatment of PE samples.
Double-blind PE samples, created from bulk materials, groundwater, surface water, or soils collected from near the sampling areas, mimic routine field samples in both matrix and contaminant concentrations. PE samples are prepared in the following matrices: groundwater, surface water, and soil.
Bulk materials have been certified for background concentrations by an independent laboratory. A sample aliquot is spiked with radiological, inorganic, or organic traceable standards.
After preparation, PE samples are sent by courier to the field sampling location where they are inserted into the field batch with other samples and sent to the laboratory for analysis. PE sample packaging and labels are identical to the field samples to ensure that they are not identified as PE samples by the commercial laboratory. PE samples are then analyzed by the laboratory along with ordinary samples; results of PE sample analyses are therefore useful in evaluating the commercial laboratory’s performance as a whole.
PE analytical results from the commercial laboratory are evaluated against documented values. Comparison studies help ensure that accurate, reliable, high-quality data are received from the commercial analytical laboratories.
Accurate, reliable, cost-effective, and quality laboratory performance is crucial to ensuring high-quality data. Performances of analytical laboratories are evaluated and compared through the Integrated Performance Indicator Program (IPIP). The objective of IPIP is to evaluate analytical laboratories based on a set of standardized performance criteria that can then be quantitatively tracked and trended. The SMO uses IPIP reports to monitor and evaluate laboratories. Satisfactory participation in the program is required for continued utilization. Laboratories are evaluated on the following criteria:
- Holding times
- Turnaround times (TAT)
- Sample disposition
- Contract compliance verification
- Data deliverables
- Data validation performance
- Single-blind performance evaluation program
- Double-blind performance evaluation program
- Audit performance/findings, responses, and close-out
By tracking these performance indicators, the SMO is able to team with the best performing laboratories. In addition, individual laboratory strengths allow the SMO to optimize laboratory selection to the needs of the project.
