A quality assurance program
is operated by the laboratory
to support the PM2.5
Chemical Speciation Air Monitoring Network.
The PM2.5 air monitoring network, managed by Office
of Air Quality Planning & Standards (OAQPS),
collects data on the levels
and composition of ultra fine particulate matter
in urban areas across the nation. NAREL performs
a variety of quality assurance
tasks to ensure the integrity and validity of the data
collected by the network. These tasks include oversight
laboratories through on-site audits,
analysis of routine quality
assurance samples, and
performance of evaluation
NAREL, in conjunction
with the National Center for Radiation Field Operations in Las Vegas, also provides quality
assurance support to the field activities associated with the network.
Field personnel receive training on air samplers, field audits
and quality assurance samples are collected and analyzed.
All of these activities ensure that decisions made by
the Agency regarding
ultra fine particulate matter are based on data of the highest quality.
