Sampling and Analysis Plan <br />5.2 Sample Packaging and Shipping <br />After collection, sample containers will be labeled, placed in ice chests (coolers), and kept cool <br />until delivery to the laboratory. Each sample container will be properly labeled in the field and <br />kept in a secure location until shipment to the contract laboratory for analysis. Appropriate <br />packing materials will be used to secure the sample bottles. Completed chain-of-custody forms <br />(Appendix B) will be placed within the cooler and a custody seal will be affixed to the cooler <br />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 field logbook and <br />on a Surface-Water or Groundwater Monitoring Form. Samples identified in the field logbook <br />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 one per each ten samples <br />(minimum of one, if less than ten samples are collected). A trip blank sample will be provided by <br />the analytic laboratory at a frequency of one trip blank per sample event. The purpose of a trip <br />blank is to evaluate sample integrity during storage and shipping of project samples. New <br />peristaltic pump tubing will be used for each sample collected, including duplicate samples. <br />Therefore, if a transfer beaker or carboy is not used to transfer water from a'sample source to the <br />laboratory sample bottles, no rinse samples will be necessary. <br />American Shale Oil, LLC 12
