Sampling and Analysis Plan <br />sampled. New peristaltic pump tubing and new filters will be used for each sample collected, <br />including duplicate samples. This procedure reduces the frequency of decontamination of <br />sampling equipment. <br />5.0 SAMPLE CUSTODY <br />The data collected during the sampling require that the possession of samples be traceable from <br />the time they were collected, through the laboratory analytical process. This section describes <br />procedures to effectively track sample custody. <br />5.1 Sample Documentation <br />In order to provide adequate information of the sampling event, the field sampling crew will <br />maintain a field logbook and Surface Water and Groundwater Monitoring Forms (see Appendix <br />B). These field documents will contain sufficient details that describe daily site conditions, <br />sample site identifications and descriptions, recorded field parameters, and site personnel. Entries <br />will be made in indelible ink, with all corrections consisting of initialed line-out deletions. A <br />sample label will be completed and adhered to each sample bottle or container. <br />The documents to be completed for each sample generated during the sampling program are: <br />• Bound field logbook <br />• Surface Water or Groundwater Monitoring Form (includes site description, sample <br />location, recorded field parameters) <br />• Sample tag and/or label <br />• Chain-of-custody transmittal form <br />Upon completion of sampling, a chain-of-custody transmittal form (see Appendix B) will be <br />filled out, and samples will be shipped by way of overnight carrier to the analytical laboratory. <br />5.1.1 Field Log Book <br />All pertinent field survey and sampling information will be recorded in a bound field logbook, <br />during each day of the field sampling and at each sample site. All entries will be made in <br />American Shale Oil, LLC 9
