SOP No. 11.0 Sample Management <br />5.3 SAMPLE HANDLING <br />This section discusses proper sample containers, preservatives, and handling and shipping <br />procedures. Tables 1, 2, and 3 summarize the information contained in this section and also <br />include the sample holding times for each analysis. <br />5.3.1 Sample Containers <br />Certified, commercially clean sample containers shall be obtained from the contracted analytical <br />lab. If appropriate, the bottles shall be labeled by the laboratory to indicate the type of sample to <br />be collected. Required preservatives shall be prepared and placed with the bottles for aqueous <br />analyses at the laboratory prior to shipment to the site. <br />5.3.2 Sample Preservation <br />All samples will be stored on ice to obtain a temperature of 4°C in an insulated cooler <br />immediately following sample collection. Soil and sediment samples do not require additional <br />preservation. As noted above, sample containers for aqueous samples will be obtained from the <br />laboratory containing the appropriate preservatives. <br />5.4 SAMPLE SHIPPING <br />Sample containers will be placed in resealable plastic storage bags and wrapped in protective <br />packing material (if appropriate). Samples will then be placed in a cooler with ice (double <br />bagged using plastic trash bags) for shipment to the laboratory. The drain on the cooler shall be <br />taped shut. Samples collected in glass containers will be packed in foam liners and bubble <br />packing or Styrofoam peanuts to ensure that no breakage occurs during shipment. A temperature <br />blank should be included in each cooler. Samples will be sent to the analytical laboratory via <br />Federal Express or equivalent. Sample shipments will be insured if needed. Shipping receipts <br />should be retained for documentation and sample tracking. <br />A completed chain-of-custody (COC) form (see Section 5.4 and Figure 2) for each cooler will be <br />placed in a Ziploc bag and placed inside of the cooler. Coolers will be wrapped with strapping <br />tape at two locations to secure lids. A signed and dated custody seal shall be placed on the <br />outside of each cooler in such a manner as to allow detection of tampering (e.g., the seal must be <br />broken to open the cooler). An example custody seal is included as Figure 3. <br />5.5 HOLDING TIME REQUIREMENTS <br />The holding time is specified as the maximum allowable time between sample collection and <br />analysis and/or extraction, based on the analyte of interest, stability factors, and preservation <br />methods. Allowable holding times for chemical analysis parameters are listed in Table 1. <br />Samples should be sent to the laboratory after collection in sufficient time to allow the laboratory <br />to meet holding time requirements. <br />4/23/07 Page 4 of 19 R Squared Inc.
