Sampling and Analysis Plan for <br /> Phase II Environmental Site Assessment <br /> South Pointe Property: 701, 705, 833, 855 West Weber Avenue <br /> Stockton, California <br /> Sample Containers, Preservation, Packaging and Shipping <br /> May 17, 2021 <br /> 7.0 SAMPLE CONTAINERS, PRESERVATION, PACKAGING <br /> AND SHIPPING <br /> The number and type of sample containers, volumes, and preservatives are listed in Table 5-2. The <br /> containers arrive pre-cleaned from the laboratory and will not be rinsed prior to sample collection. <br /> Chemical preservatives are not required for the selected analytical methods. <br /> 7.1 SOIL SAMPLES <br /> Soil samples for OCP analysis will be transferred from the backhoe bucket or soil pile into 8-ounce wide- <br /> mouth glass jars using a trowel. The samples will be chilled to 4°C immediately upon collection. <br /> 7.2 SOIL VAPOR SAMPLES <br /> Passive soil gas sample modules supplied by Beacon consist of sorbent material inside a glass vial with a <br /> perforated cap. The vials are suspended inside the subsurface borehole at a depth of approximately 12 to <br /> 36 inches via a length of wire. Upon retrieval, the perforated cap on each vial is replaced with a solid cap, <br /> the vial is placed back into laboratory-supplied shipping materials, and sample vials shipped to Beacon <br /> for analysis. Active soil vapor samples will be collected into laboratory-supplied Summa canisters and <br /> returned to the laboratory in their original shipping container. No cooling, preservative, or special handling <br /> is required for passive or active soil vapor samples. <br /> 7.3 PACKAGING AND SHIPPING <br /> Sample containers will be placed in a rigid-walled shipping container. Packaging procedures are <br /> described below. <br /> 1. If used, wet ice will be packed in zip-lock, double plastic bags. The drain plug of the cooler will be <br /> sealed with fiberglass tape to prevent melting ice from leaking out of the cooler. <br /> 2. The bottom of the cooler shall be lined with bubble wrap to prevent breakage during shipment. <br /> 3. Screw caps will be checked for tightness. <br /> 4. Bottle/container tops will be sealed with clear tape and custody seals. <br /> 5. Sample labels will be fixed to the containers with clear tape. <br /> 6. Glass sample containers will be wrapped in bubble wrap to prevent breakage. <br /> M <br /> Project No.: 185704833.5.3&5.4 7.1 <br />
