Groundwater Sampling ana Analysis Plan <br /> Former Texaco Service Station <br /> Chevron Site ID 309075 <br /> January 14, 2011 <br /> additional control may be necessary. Surrogate spike compounds will be selected utilizing the <br /> guidance provided in the analytical methods. <br /> 5.3 SAMPLE PACKING AND SHIPPING PROCEDURES <br /> A The following sections discuss the proper sample labeling, chain-of-custody (COC), sample <br /> packing and shipping procedures. <br /> 5.3.1 Sample Labeling <br /> A waterproof sample label will be affixed to all sample bottles for proper identification. An <br /> indelible ink pen/marker will be used to write the sample information on the label. The <br /> information on the sample label will be duplicated on the COC form as described in the following <br /> section. <br /> 5.3.2 Sample Custody <br /> Procedures to ensure the custody and integrity of the samples begin at the time of sampling and <br /> continue through transport, sample receipt, preparation, analysis and storage, data generation <br /> and reporting, and sample disposal. Records concerning the custody and condition of the <br /> samples are maintained in field and laboratory records. All samples will be uniquely identified, <br /> labeled, and documented in the field at the time of collection and recorded on the COC form. <br /> 5.3.3 Packing and Shipping <br /> Subsequent to collection, samples will be packed on ice, cooled to approximately 4 degrees <br /> Celsius (°C) and shipped under appropriate COC protocols for analysis. When, in the judgment <br /> of the laboratory, the temperature of the samples upon receipt may have affected the stability of <br /> the analytes of interest, the problem will be documented in laboratory records and discussed <br /> with ARCADIS personnel. The resolution of the problem will also be documented. <br /> 5.4 WASTE DISPOSAL <br /> Site cleanup associated with the sampling event will be performed after monitoring and <br /> sampling activities at each well location has been completed and prior to moving any equipment <br /> to the next well location. Clothing, gloves, boot covers, and rags, which may be used during the <br /> field activities (as warranted), will be disposed of in onsite receptacles (if present) or <br /> containerized in plastic garbage bags and transported offsite for disposal. Purge water and <br /> equipment decontamination water generated during the sampling event will be collected by G-R, <br /> transported by G-R to their temporary storage facility in Dublin, California and staged until it can <br /> be properly disposed of by Integrated Wastestream Management, Inc. (IWM). <br /> \\CA5FP\Data\Hproject\ENV\CHEVRON\309075\6 Deliverables\Work Plan\SAP\309075_SAP_6671110950.doc 9 <br />
