MAPEP Program Description
 Assures the quality, accuracy and defensibility of environmental
analytical measurements.
 Ensures valid analytical data which is critical to worker and
environmental protection for minimizing DOE’s liability and risk
 Evaluates analytical work based on performance.
 Addresses specific analytical issues routinely encountered that
affect the accuracy of the results.
 Tests the accuracy of analytical procedures on a variety of real
samples being submitted to DOE for analysis.

MAPEP Programmatic Updates
 Ongoing funding efforts to sustain current program
and manage inflationary cost growth
 Suspension or elimination of participants and selected
PT matrices
 Technical Highlights for 2016
3
Budgetary Impacts to MAPEP
 Suspension of the following PT areas:
 International Participation
 Organic PT (OrW and OrS)
 Gross alpha/beta (GrW and GrF)

DOE Expects Quality Results
“High bias to the Pu-239/240 results are expected”
“Attempts to remove this Po-210 interference on these samples in the past have
been unsuccessful. Thus, the results are submitted without further qualifications.”
28
Summary
 MAPEP continues to identify and solve analytical/laboratory
problems that are otherwise difficult to recognize before they
become a DOE liability.
 Tests the accuracy and reliability of analytical procedures on a
variety of real samples being submitted to DOE for analysis.
 Addresses specific analytical issues routinely encountered that
affect the accuracy of the results.
 MAPEP is a federal oversite program that is critical in assuring
consistent and reliable laboratory data.
