Appendix B for more details). Laboratory personnel will document the identification number <br />on the Chain of Custody form. <br />All sample bottles will be supplied by the contracted laboratory. Sample bottles will be pre - <br />cleaned to guidelines established by the EPA in Specification and Guidance for Contaminant - <br />Free Sample Containers. To ensure the integrity of the sample, the sampling lead or designee <br />is responsible for the care, packaging, and custody of the samples until they are dispatched to <br />the laboratory. Section B.3, "Standard Practice for Chain of Custody and Physical Security of <br />Samples," in Appendix B will be implemented to provide a secure sample and document sample <br />custody. <br />The sampling lead personnel will be responsible for ensuring that the samples are transferred <br />to the laboratory in sufficient time for the laboratory to complete extraction/analysis prior to <br />the expiration of sample holding times. If a commercial carrier sends the packages, receipts <br />and any other shipping -related documents must be retained as part of the chain of custody <br />documentation. The laboratory services coordinator will retain carrier and shipping receipts as <br />long as they have value associated with the laboratory sample receiving activities. <br />Chain of custody records document all transfers of sample possession and show that the <br />samples were in constant custody between collection and analysis. A chain of custody form will <br />accompany samples sent or transported to an analytical laboratory by individuals other than a <br />member of the field sampling team, with a copy retained on file by the originator. <br />5 Decontamination of Sampling Equipment <br />Decontamination of non -dedicated sampling equipment will be accomplished by rinsing all <br />equipment surfaces with diluted detergent, scrubbing as necessary, followed by deionized <br />water as described in Section B.5, "Standard Practice for Decontamination of Field Equipment" <br />(Appendix B). Decontamination of non -dedicated sampling equipment will be conducted <br />immediately after use at a sampling location. Between sampling events, decontaminated <br />equipment will be stored in protective containers or sealed plastic bags when feasible and <br />appropriate. <br />6 Analytical Program <br />The monitor well name, monitoring frequency and type for each site is specified in Appendix A. <br />A list of analytes, typically requested by the BLM or other agencies, may be found in Table 3 <br />with additional detail contained in the NS Environmental Monitoring Plan and the Code of <br />Federal Regulation (40 CFR, Chapter 1, Subchapter D, Part 136, 2009 edition).
