FINAL SAMPLING AND ANALYSIS PLAN - Documents for Moffett Field

WORKSHEET #34: VERIFICATION (STEP 1) PROCESS TABLE
This worksheet describes the processes that will be followed to verify project data quality.
The table below describes how each item will be verified, when the activity will occur,
what documentation is necessary, and who the responsible person is.

Description
Chain-of-custody forms will be reviewed by the project team in the
field upon completion and verified against the packed sample
coolers they represent. The shipper’s signature on the chain-ofcustody
will be initialed by the reviewer, a copy of the chain-ofcustody
retained in the project file, and the original and remaining
copies taped inside the cooler for shipment.
A copy of all audit reports will be placed in the project file upon
completion. If corrective actions are required, a copy of the
documented corrective action taken will be attached to the
appropriate audit report in the project file. At the beginning of each
week and at the completion of the site work, project file audit reports
will be reviewed internally to ensure that all appropriate corrective
actions have been taken and that corrective action reports have
been attached. If corrective actions have not been taken, the project
manager will be notified to ensure action is taken.
Field notes will be reviewed internally and placed in the project file.
A copy of the field notes will be attached to the final report.
All laboratory data packages will be verified internally by the
laboratory performing the work for completeness and technical
accuracy prior to submittal.
All data packages will be verified externally by data validator who is
not associated with the collection and analysis of samples,
interpretation of sample data, or with any decision-making process
within the scope of this investigation. The EWI #1 3EN2.1-specified
data validation strategy for this project is 20% Level IV data
validation and 80% Level III data validation for all laboratory data. In
Level III data validation, data quality is assessed evaluating
parameters by the appropriate criteria (or limits) specified in
Worksheets 12, 19, and 28 of the project SAP, Contract Laboratory
Program (CLP) requirements, EWI 3EN2.1 requirements, or the
analytical methods. If calculations for quantitation are verified, it is
done on a limited basis and may require raw data in addition to the
standard data forms normally present in a data package.
Level IV data validation follows the EPA protocols and CLP criteria
set forth in the functional guidelines for evaluating organic and
inorganic analyses (EPA 1999, 2004). Level IV data validation
consists of Level III data validation as well as checking calculations
of quantified analytical data, including routine field samples and field
and laboratory QC samples. Additionally, instrument performance,
calibration, and calibration standard data are evaluated to ensure
that detection limits and data values are appropriate.
