Mixed Analyte Performance Evaluation Program (MAPEP)
DOE Analytical Services Program (ASP)
The MAPEP serves as a valuable quality assurance tool for the DOE and is currently
the only DOE performance evaluation program providing quality assurance oversight
for environmental analytical services across the DOE Complex. It is also the only
proficiency testing program that includes radiological, stable inorganic, and organic
constituents (i.e., mixed analytes) in the same single-blind sample for analytical
performance evaluation. The samples use various matrices including soils, water,
vegetation, and air filters. It is important to note that the MAPEP samples are
not a mixed waste.
- Over one hundred domestic analytical laboratories that directly or indirectly support
the Departments' mission or interests participate in the MAPEP. All matrices are
distributed twice per year (i.e., January and July), with performance data available
on the MAPEP web site. With the Department opening up domestic laboratory participation
in the MAPEP based upon public interest to increase laboratory capabilities in case
of an National emergency event, the number of laboratories involved in the MAPEP
is expected to increase in the future.
- MAPEP supports international laboratory participation. The MAPEP provides proficiency
testing for the Radiation Measurements Cross Calibration Project in the Middle East.
This project is facilitated by the Sandia National Laboratories in collaboration
with the International Atomic Energy Agency. Participants include Saudi Arabia,
Jordan, Kuwait, Qatar, United Arab Emirates, Oman, Morocco, Lebanon, Tunisia, Turkey
and others as part of establishing quality assurance and cross calibration for radiological
measurements. Through Departmental agreements for nuclear nonproliferation and the
Nuclear Test Ban Treaty, the nations of Brazil, the Netherlands, Bolivia, New Zealand,
Ecuador, Spain and others are involved in MAPEP proficiency testing and evaluation.
Cooperative Air Monitoring is also conducted with Canada and the United Kingdom.
International laboratory participation is expected to grow in the future and currently
includes nearly thirty laboratories.
