Site-Specific Health and Safety Plan (HASP) - Laschools.org

• Use of appropriate sampling procedures, including proper equipment and
equipment decontamination;
• Use of appropriate analytical methods for the required parameters and adequate
practical quantitation limits (PQLs); and
• Analysis of samples within the required holding times.
Sample representativeness is also affected by the portion of each sample chosen for
analysis. The laboratory will adequately homogenize all samples prior to taking aliquots
for analysis to ensure that the reported results are representative of the sample received.
Because many homogenization techniques may cause loss of contaminants through
volatilization, homogenization will not be performed for any volatile organic compound
(VOC) method analyses.
2.2.6 Sensitivity
The concentration of any one target compound that can be detected and/or quantified is a
measure of sensitivity for that compound. Sensitivity is instrument-, compound-,
method-, and matrix-specific. The definitions of terms relating to sensitivity and DQOs
are presented in Section 6.2.
2.3 LABORATORY QA OBJECTIVES
The selected laboratory will provide a copy of the laboratory quality assurance plan
(QAP). The QAP shall define internal laboratory procedures for QA/QC and shall
include descriptions of the following:
• QA policies and objectives;
• Organization and personnel;
• Document control;
• Analytical methodology standard operating procedures (SOPs);
• Data generation;
• Sample custody, preservation and tracking;
• Data recording, reduction, review, reporting, and validation for both hard copy and
electronic formats;
• Security;
• Documentation of client-specific requirements;
• QA audits;
• QC; and
• Non-conformance/corrective action report (NC/CAR) procedures.
The laboratory QAP must be approved by the Parsons PM prior to the initiation of
analyses on this project.
