subsequently be validated by the USACE, or select currently validated USACE
laboratories. The Contractor shall identify all proposed project
laboratories [no later than the coordination meeting] [in the sampling and
analysis plan (SAP)]. If a proposed analytical laboratory cannot meet
specified analytical requirements or achieve the required validation, the
Contractor shall select another laboratory. If not currently validated,
the USACE laboratory validation process requires a nominal 120 day process.
1.6.2
QA Sample Collection and Analysis
**************************************************************************
NOTE: The designer should ensure that the number or
frequency of QA samples is clearly specified. In
addition, the designer should identify the address
and point of contact for the QA laboratory.
It is the responsibility of the Contracting Officer
(CO) to report any significant discrepancies between
the primary and QA laboratory results to the
Contractor. In the event of such an occurrence, the
Contractor must initiate an investigation into
possible reasons for the discrepancies and submit a
plan to resolve any problems that are identified.
**************************************************************************
The Contractor shall be responsible for collection and transportation of QA
samples to the QA laboratory. Samples for all analyses (except volatiles)
shall be taken as splits of homogenized samples. Samples for volatiles
shall be collected as discrete duplicates/triplicates. Samples shall be
collected at a rate of [_____] percent per matrix per analysis per sampling
event.
a.
The Contractor shall submit the QA Laboratory Advance Notification
(QALAN) to the QA laboratory. The QALAN shall include a list of
laboratory-related DQO. The DQO shall include, but shall not be
limited to, identification of extraction and analysis method
numbers, a list of analytes with required limits, estimated number
of tests, approximate sampling dates, and requested completion
date for QA testing. The Contractor shall notify the Contracting
Officer (CO) and the QA laboratory immediately of any changes.
b.
The Contractor shall provide all labor and field supplies,
including sample containers and shipping coolers, for collecting
and shipping samples for QA testing. The Contractor shall, in the
presence of the CO, properly collect, label, and package the QA
samples, fill out all chain-of-custody forms, and ship the samples
by one-day delivery service to the designated QA laboratory for
analysis. The Contractor shall notify the laboratory when all
sampling is completed and shall clearly mark the chain-of-custody
form accompanying the final shipment "FINAL" in 25 mm 1 inch high
c.
The Contractor shall allow [60 calendar] [_____] days for
laboratory analysis of QA samples, data review, and submission of
the Government chemical quality assurance report. The elapsed
time shall begin when the Contractor's last sample arrives at the
QA laboratory, provided that the Contractor's completed chemistry
data package is received within 30 calendar days thereafter.
Otherwise, the Contractor shall allow 30 calendar days from the
