FM before sending any samples originally scheduled to be analyzed at its facility to
another laboratory. Analyses will not be performed on samples whose integrity has been
compromised or is suspect, without prior approval from the FM.
5.6 SAMPLE HANDLING
Laboratory sample custody will be maintained by the procedures detailed in the
laboratory QAP.
• If the chain-of-custody and samples correlate, and there has been no tampering
with the custody seals, the "received by laboratory" box on the chain-of-custody
form will be signed and dated.
• The samples will be logged into the laboratory information management system in
such a manner that tracking the status of the samples (extraction, analysis dates)
can be readily accomplished.
• Water samples will be stored in a secured area at a temperature of approximately 4
± 2 degrees Celsius (°C) for all analytical fractions except for metals. Soil samples
may be stored at lower temperature (as applicable) until analyses commence.
Samples must be stored in coolers separate from those used to store analytical
standards, reagents, and/or QC samples.
• Volatile samples will be stored separately from other samples. A storage blank
must be present in the cooler storing volatile samples and analyzed weekly at a
minimum. Results of storage blank analyses must be maintained by the QA
department. Corrective action is required if analyses provide evidence of cross
contamination.
• The original chain-of-custody form will accompany the laboratory report submittal
and will become a permanent part of the project records.
• Data generated from the analysis of samples also must be kept under proper
custody by the laboratory.
Disposal of sample containers and remaining sample material will be the responsibility of
the laboratory. Samples should be disposed of appropriately when all analyses and
related QA/QC work are completed (Section 15).
5.7 LOGGING SOIL BORINGS
Boring logs will be prepared in conformance with ASTM Method D2488. Boring logs
will record the following sampling information: boring number and location; sample
identification numbers; date and time; sample depth; lithologic description in accordance
with the Unified Soils Classification System (USCS); description of any visible evidence
of soil impacts (i.e., odor, staining); and organic vapor readings. Soils will be described
as follows:
• Soil moisture: Soils will be described as wet, moist, or dry per ASTM Method
D2488.
