sampled together, but must be analyzed and reported separately. When analyzing
samples consisting of more than one component, each sub-component shall be
analyzed and the analytical results reported separately, but listed together as a single
sample consisting of several components. Specify the requirement for collection and
analysis of multi-layered systems.
*******************************************************************************
The Contractor shall assure that the laboratory follows the guidance provided in PWTB 420-70-8,
Chapter 8-4 "Analysis of Bulk Samples for Asbestos" for all bulk sample analyses. Bulk samples
collected by the Contractor during the survey(s) shall be analyzed by polarized light microscopy
(PLM). TEM analysis shall be performed on the samples when PLM analysis is inclusive for
percent (%) asbestos.
The most current version of the methodology shall be used. Use of other methodologies must be
accepted in advance by the COTR. Results shall be reported in units of percent (%). Multi-layered
systems shall be surveyed and assessed in the following manner [insert appropriate text]
2.3.2.1
Laboratory Turnaround Time
The Contractor shall submit the laboratory report analytical results to the COTR within [insert
number of days] days of the sampling.
2.3.3
Quality Assurance and Quality Control (QA/QC)
The Contractor shall establish a QA/QC protocol according to EPA 560/5-85-024, June
1985, Guidance for Controlling Asbestos-Containing Building Materials. QA/QC sample
information must be carefully documented in the Asbestos Survey and Assessment Report,
including the Asbestos Sampling Plan and Sample Location Documentation, analytical
results, and Chain-of-Custody records. The Contractor shall collect a minimum of one QC
sample for every twenty investigative samples collected. [QA/QC samples shall be sent to
a different [NVLAP] [or] [AIHA] accredited laboratory [and not the primary laboratory
subcontracted]]. The Contractor shall specify the most advantageous technique to provide
extra samples to the laboratory, should additional samples be required by the laboratory to
replace sampling or QA/QC data lost due to laboratory mistakes. The Government is not
liable for cost of additional sample collection due to laboratory mistakes, Contractor sample
collection problems, or chain-of-custody errors.
2.3.3.1
Laboratory QA/QC
The Contractor shall verify that sample duplicates and laboratory blanks are used by the laboratory
to measure precision and accuracy of laboratory analytical procedures in accordance with
[NVLAP] [or] [AIHA] requirements.
2.3.4
Laboratory Report
The Contractor shall require that the laboratory provide the information necessary for the
Contractor to comply with the data evaluation/validation procedures outlined in this SOW. This
shall be included in a package containing the following information:
