Refer to the Sample Analysis Plan for a summary of the information contained in <br />this section. <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.
