' A-2 <br /> } This number provides a relative comparison of the petroleum hydrocarbon concentration with the soil <br /> samples but is not quantitative <br />' 2.0 QUALITY ASSURANCE PLAN <br /> This section describes the field and analytical procedures to be followed <br /> 2.1 General Sam le-Collection and. Handling Procedures <br />' Proper collection and handling are essential to ensure the quality of a sample Each sample will be <br /> collected in a suitable container, preserved correctly for the intended analyses, and stored prior to analysis <br /> for no longer than the maximum allowable holding time Details on the procedure for collecting and <br /> handling of soil and ground water samples to be used on this project can be found in Section 1 0 <br /> 2.2 Sample Identification and Chain-0f-CustodyProcedures <br />' Sample identification and chain-of-custody procedures ensure sample integrity and document sample <br /> possession from the time of collection until analysis When the samples are shipped, the person in <br /> custody of them will relinquish the samples by signing the chain-of-custody form and noting the time <br /> The sample-control officer at the laboratory will verify sample integrity and confirm that it is in the <br />' property container, preserved correctly, and that there is adequate volume for analysis When these <br /> conditions are met, the sample will be assigned a unique log number for identification throughout analysis <br /> and reporting The log number is recorded on the chain-of-custody form and in the legally-required log <br /> book maintained in the laboratory The sample description, date received, cIient's name, and any other <br />' relevant information will also be recorded Each sample container submitted for analysis will have a label <br /> affixed to identify the job number, sampler, date and time of sample collection, and a sample number <br />' unique to that sample This information, in addition to a description of the sample, field measurements <br /> made, sampling methodology, names of on-site personnel, and any other pertinent field observations will <br /> be recorded on the borehole log or in the field records Samples will be analyzed by a <br /> California-certified Iaboratory. <br /> A chain-of-custody form will be used to record possession of the sample from time of collection to its <br /> arrival at the laboratory When the samples were shipped, the person in custody of them will relinquish <br /> 1 <br />' RPr066 TA <br />
