DGM Environmental Monitoring QAPP <br /> Section 6 SAMPLE PROCESSING <br /> Two aspects of sample processing from field acquisition through laboratory analysis are <br /> addressed in this section: 1) sample handling and 2) sample documentation. Sample <br /> handling implies routine field and lab handling practices. Sample documentation <br /> includes sample record and data management. These aspects are inter-related. <br /> 6.1 Field Practices <br /> In this section field practices refer to those that are conducted by DGM personnel or <br /> their agents. <br /> 6.1.1 Sample Handling in the Field <br /> 6.1.1.1 Sample Acquisition <br /> Sampling equipment will be properly decontaminated according to manufacturer's <br /> manual prior to sample acquisition. <br /> 6.1.1.2 Sample Labeling <br /> The sample collector labels all sample containers with permanent ink at the time of <br /> sample collection. Each container is labeled with the sample date, sample location and <br /> chain of custody identification. Other information such as: project or special sample <br /> name, field preparation status, preservative addition, etc. may also be specified on the <br /> sample container and/or chain of custody document as prescribed by specific task <br /> sampling requirements. The individuals performing the sampling will provide this <br /> information. <br /> 6.1.1.3 Sample Security <br /> Individuals performing the various sampling tasks are responsible for maintaining <br /> sample security from the time of sample collection until the time the sample is received <br /> by the laboratory. Once the sample has been collected and until it is transmitted to the <br /> laboratory for analysis it will be in the sampler's possession under his attention, kept in <br /> a secure location, or within a container which has been secured through the provision of <br /> a security seal. <br /> 6.1.1.4 Sample Shipment <br /> Shipment of all samples to third party laboratories will require that samples under go all <br /> prescribed preparation and preservation practices including maintenance of constant <br /> cold storage temperature and unbroken security seals on the shipping container <br /> throughout the duration of the shipping process up to the official documentation of <br /> sample reception and acceptance by the receiving laboratory. <br /> Page 7 <br />
