Sampling and Analysis Plan - Operations & Post-Operations <br />0 5.2 Sample Packaging and Shipping <br />After collection, sample containers will be labeled, placed in ice chests (coolers), and iced <br />sufficiently to keep cool (4° to 6° C). until delivered to the laboratory. Each sample container <br />will be properly labeled in the field and kept in a secure location until shipment to the contract <br />laboratory for analysis. Appropriate packing materials will be used to secure the sample bottles. <br />Completed chain-of-custody forms (Appendix B) will be placed within the cooler and a custody <br />seal will be affixed to the cooler prior to transport to the laboratory. <br />6.0 QUALITY CONTROL SAMPLES <br />Quality assurance/quality control (QA/QC) samples will be used to check the precision and <br />accuracy of analyses completed by the analytical laboratory. QA/QC samples will not have any <br />unique identifying codes that will enable the laboratory to bias them. The sampling team will <br />strive to obtain uniformity in the sampling technique and preparation of QA/QC samples to limit <br />potential sampling errors. The QA/QC samples will be identified only in the bound field logbook <br />and on a Surface-Water or Groundwater Monitoring Form. Samples identified in the bound field <br />is logbook will include: <br />• Site sample <br />• Duplicate sample <br />In addition to investigative samples, duplicate samples will be collected and trip blank samples <br />will be provided for QA/QC purposes. Duplicate samples will be collected from the same source <br />and at the same time as the primary sample. Duplicates will be taken at a proportion of one per <br />each ten samples (minimum of one, if less than ten samples are collected). A trip blank sample <br />will be provided by the analytic laboratory at a frequency of one trip blank per sample event. The <br />purpose of a trip blank is to evaluate sample integrity during storage and shipping of project <br />samples. New peristaltic pump tubing will be used for each sample collected, including duplicate <br />samples. Therefore, if a transfer beaker or carboy is not used to transfer water from a sample <br />source to the laboratory sample bottles, no rinse samples will be necessary. If a transfer beaker or <br />carboy is used by at least half of the total number of samples collected in any one sampling event, <br />a rinse sample of the transfer beaker or carboy will be collected. <br />• <br />American Shale Oil, LLC 13
