not available, other nationally recognized
methods such as those of DOE, EPA, and ASTM
were used. Analytical methods were identified
in an analytical SOW. Using guidance from
EPA, the laboratories document the steps in
handling, analysis, and approval of results.
Chain-of-custody procedures were followed
until a sample was analyzed.
Laboratory Quality Control Samples
Laboratory QC samples were prepared and
analyzed as required by the analytical methods
used. Typical' laboratory QC samples are
identified in Table 11.1. If acceptance criteria
were not met for the QC samples, then
appropriate action, as denoted by the analytical
method, was taken or appropriate qualification
of the data occurred.
participation is voluntary so that each laboratory
can select parameters of particular interest to that
facility. These programs are conducted by EPA,
DOE, and commercial laboratories.

Independent Quality Control
The 'Paducah Site is directed by DOE and
EPA to participate in independent QCprograms.
The . site also participates in voluntary independent
programs to improveanalytical~C. These
programs generate data that are readily
recognizable as objective measures, allowing
participating laboratories and government
agencies a periodic review of their performance.
Results that exceed acceptable limits are
investigated and documented according to
formali procedures.' Although participation in
certain programs is mandated, the degree of
Project Environmental Management
System
The data generated .by the EM program are
stored in PEMS, a consolidated site data system
for tracking and managing data:. PEMS is used to
manage field-generated data; import laboratorygenerated
data; input data qualifiers identified
during the data review process; and transfer data
to. the Paducah OREIS for reporting. PEMS uses
a variety of references and code lists to ensure
consistency and to standardize the presentation
of data for users.
