r S E C O R <br /> STANDARD PROCEDURE FOR <br /> SOIL SAMPLING <br /> Undisturbed or disturbed samples may be collected, depending on the requirements of the <br /> project. Undisturbed samples are collected by driving a clean spoon sampler lined with a brass <br /> or stainless steel liner into the undisturbed soil mass. The sample is carefully packaged for <br /> chemical analysis by capping each end of the sample liner with a Teflon sheet followed by a <br /> tight-fitting plastic cap and sealing the cap with non-VOC, self-adhering silicon tape. Disturbed <br /> samples may also be collected from the soil cuttings contained in backhoe bucket, cutter head <br /> or other sampler. Disturbed samples may also be collected in brass sampling tubes as <br /> described previously or in glass jars. Samples collected in glass jars are hand packed (using <br /> disposable Neoprene or latex gloves) into pre-cleaned glass jars to preclude headspace, sealed <br /> with a Teflon-lined screw cap lid and labeled for identification. <br /> A label is affixed to the sample indicating the sample identification number, borehole number, <br /> sampling depth, sample collection date and time, the sampler's name, job number, etc. The <br /> sample is then annotated on a chain-of-custody form and placed in an ice-filled cooler for <br /> transport to the laboratory. <br /> Related Procedures: <br /> • Standard Procedure for Equipment Decontamination <br />
