A-2 <br /> Upon recovery, the three soil sample tubes were removed from the sampler. One portion of the soil <br /> sample was placed in a ziplock bag for screening with an photoionization detector (PID), and another <br /> portion of the soil sample was used for classification and description. One of the soil sample tubes was <br /> sealed and stored at approximately VC for transport to the laboratory. The soil samples retained in <br /> ziplock bags were allowed to warm to ambient temperature, inducing volatilization of petroleum <br /> hydrocarbon vapors, and the headspace vapors were analyzed with a PID equipped with a 10.2 eV lamp <br /> calibrated to hexane. The highest observed reading was recorded on the soil boring log. <br /> Each soil sample submitted for analysis had a label affixed to identify the job number, sample date, time <br /> of sample collection, and a sample number unique to that sample. This information, in addition to a <br /> description of the sample, field measurements made, sampling methodology, names of on-site personnel, <br /> and any other pertinent field observations, were recorded on the boring log or in the fold notebook. <br /> Samples were analyzed by a California-certified laboratory. <br /> A chain-of-custody form was used to record possession of the sample from time of collection to its arrival <br /> at the laboratory. When the samples were shipped, the person in custody of them relinquished the <br /> samples by signing the chain-of-custody form and noting the time. The sample control officer at the <br /> laboratory verified sample integrity and confirmed that it was collected in the proper container, preserved <br /> correctly, and that there was an adequate volume for analysis. <br /> LRP l 30.SSH <br />
