FINAL SAMPLING AND ANALYSIS PLAN - Documents for Moffett Field

14.2.5 Import Soil Sampling Procedure
Soil to be used for import soil will be collected and analyzed for PCBs, metals, asbestos
and pH prior to transporting to the site. It is anticipated that the material to be used will be
from land near rock quarry. Based on the Information Advisory Clean Imported Fill
Material fact sheet developed by the Department of Toxic Substance Control (DTSC)
(DTSC 2001), five soil samples will be collected using following procedure:
• The soil area will be divided into the number of sections equivalent to 500 cubic
yards per sample.
• The sample locations will be determined by generating random numbers.
• Sampling personnel will don a new pair of disposable nitrile gloves immediately
before collecting samples at each location.
• A hand auger, or similar device, will be used to access each x, y, and z coordinate.
Due to limitations in accessing deep depths in a large soil area, z-coordinates may be
limited to 10 feet.
• Once the sample location has been accessed, grab samples will be collected by
inverting the hand auger with the material and dislodging the material into an 8-
ounce glass jar.
• Place sample containers in an insulated cooler with ice.
• Samples will be packaged and shipped in accordance with SOP FP-F-7, Sample
Handling, Storage, and Shipping (Appendix A).
14.3 Analytical Tasks
Baseline/pre-construction and confirmation soil and sediment samples will be analyzed for
PCBs, lead and asbestos. If import soil is required, soil samples will be tested for PCBs,
asbestos, metals and pH. Wipe samples from concrete floor of Hangar 1 will be analyzed
for PCBs, and lead. Samples will be analyzed for PCBs including Aroclor-1268 by EPA
method 8082, lead and metals by EPA method 6010B, pH by EPA method 150.1, and
asbestos by California Air Resource Board (CARB) 435 method. Samples will be sent to
an off-site laboratory evaluated by NFESC or will hold the DoD ELAP certification, and
the California Department of Public Health ELAP certification (for methods certified by
California).
14.4 Quality Control Tasks
Soil samples will be collected using procedures presented above. Field QC samples to be
collected are presented in WS #12. Sample collection activities will be documented in
