Field Sample Management Standard Operating Procedure <br /> SWE-FSOP-002;Revision 1 Ahtna Southwest Environmental Operations <br /> 4.4 Sample Integrity <br /> To reduce the possibility of invalidating the results, all <br /> collected samples must be placed in laboratory-suppliedSite: Titan 1A <br /> AMAX Loc Code: MIAL11 <br /> containers and labeled (Figure 1). Samp ID: MW-11-NS1-2108 <br /> Lab:TASEA Cont.:glass vatfeflon lined septa 40 ML <br /> Sample preservation before laboratory analysis is Fil: N Prsv.: HCL <br /> accomplished by adding the sample into pre-preserved Analysis: VOCs SW8264D LL <br /> sample containers or adding the preservative afterfilling <br /> the container. Preservation requirements are described Sampler: Date,Time: <br /> in Worksheet# 19/30 of the project Quality Assurance Figure 1. Example Container Label <br /> Project Plan (QAPP). <br /> With few exceptions (i.e., metal analyses), samples must be cooled as soon as possible after sample <br /> collection, and after that, maintained between 0°C-6°C. Samples must be kept in the custodians' <br /> possession or stored safely at all times. <br /> Sample containers should be pre-labeled as much as practical before sample collection. Labels should be <br /> affixed to the sample container before or at sampling and must adhere firmly to the container. Labels can <br /> be further secured by placing clear packaging tape over the label, but not for volatile organic compounds <br /> (VOC) or gasoline range organics (GRO) analyses. <br /> Sample containers that are weighed by the laboratory before use should not have any additional labels <br /> placed on the container, affecting the weight. For those containers, use the label already provided on the <br /> jar. Only one label should be placed on each sample container. <br /> Use the specifications defined in the project work plans. Unless the QAPP specifies otherwise, sample <br /> labels should be written in indelible ink and contain, at a minimum,the following information: <br /> • Project number/Site <br /> • Field sample ID <br /> • Container type and preservative <br /> • Filtered (Y/N) <br /> • Laboratory name <br /> • Analysis requested (abbreviated) <br /> • Sampler's organization and initials <br /> • Collection date and time (24-hour <br /> clock) <br /> Page 8 of 12 <br />
