by the laboratory. The Contractor shall complete and maintain chain-of-custody forms for each set
of samples shipped to the laboratory, and a copy of the forms shall accompany each shipment of
samples. The labeled sample containers (i.e., zipper sealed baggie) shall be packaged and shipped
in sturdy containers. Corresponding chain-of-custody documentation shall accompany each
shipping container to the laboratory. The shipping container shall be securely taped shut and a
custody seal shall be placed across the seams between the lid and the body of the shipping
container. All shipping containers shall be [express] mailed to the laboratory. The samples shall
be mailed, at a minimum, on a [weekly] [insert time period] basis during the project's duration.
2.2.5
Decontamination
Field sampling equipment shall be decontaminated following standard methods. At a minimum,
the field decontamination procedures for non-disposable sampling equipment (e.g., knives and
coring devices) shall consist of either wiping off the equipment twice using a clean wet wipe or
washing in a solution of non-phosphate detergent, and rinsing with distilled water. The equipment
shall be decontaminated prior to each use, between each sample collection, and prior to leaving the
site. The Contractor shall coordinate with the installation environmental officer to determine
requirements for disposal of sampling decontamination waste, and used personal protective
equipment.

TASK 3 SAMPLE DATA ANALYSIS, EVALUATION OF FINDINGS
2.3.1
Sample Preparation and Analysis
*******************************************************************************
NOTE: Army guidance specifies that the laboratory performing the analyses of bulk
samples all be accredited by NVLAP. The AIHA also accredits laboratories for bulk
samples. Normally requirements for the use of NVLAP accredited Laboratories will
be specified. Consult with the customer and the state to determine what accrediting
status is required.
*******************************************************************************
Samples collected during the survey and assessment(s) shall be sent to a laboratory accredited by
[NVLAP] [or] [AIHA] for analysis. The laboratory must be accredited for each type of analysis
required. Bulk samples collected by the Contractor during the survey shall be analyzed for asbestos
using polarized light microscopy (PLM) [and transmission electron microscopy (TEM)].
2.3.2
Analysis of Bulk Samples
*******************************************************************************
NOTE: There is a conflict between the OSHA construction worker protection
asbestos standard and the EPA NESHAP standards regarding the composting or
segregating of multi-layered systems during analysis. For example, OSHA considers
wallboard, joint compound and joint tape as separate products. Therefore, under
OSHA the wallboard, the joint compound and the joint tape must be analyzed
separately. EPA, however, looks at wallboard, joint compound and joint tape as a
single system and requires only a single, composite analysis of the three
components. Another example is floor tile and mastic; these materials may be
