LOG SHEET or in the DAILY FIELD RECORD as a means of identifying and tracking the <br /> samples. Following review by the project manager, the original field records will be kept in <br /> the project file. <br /> 4.2 CHAIN-OF-CUSTODY PROCEDURES <br /> After samples have been collected and labeled, they will be maintained under chain-of-custody <br /> procedures. These procedures document the transfer of custody of samples from the field to <br /> the laboratory. Each sample sent to the laboratory for analysis will be recorded on a CHAIN- <br /> OF-CUSTODY RECORD, which will include instructions to the laboratory on the analytical <br /> services required. <br /> Information contained on the triplicate CHAIN-OF-CUSTODY RECORD will include: <br /> • Project number <br /> • Signature of sampler <br /> • Date and time sampled <br /> • Sample I.D. <br /> • Number of sample containers <br /> • Sample matrix (soil, water, or other) <br /> • Analyses required <br /> • Remarks, including preservatives, special conditions, or specific quality <br /> control measures <br /> • Turnaround time and person to receive laboratory report <br /> • Method of shipment to the laboratory <br /> • Release signature of sampler and signatures of all people assuming <br /> custody <br /> ° Condition of samples when received by laboratory (to be completed by <br /> the laboratory) <br /> Blank spaces on the CHAIN-OF-CUSTODY RECORD will be crossed out between the last <br /> sample listed and the signatures at the bottom of the sheet. <br /> The field sampler will sign the CHAIN-OF-CUSTODY RECORD and will record the time <br /> and date at the time of transfer to the laboratory or an intermediate person. A set of signatures <br /> is required for each relinquished/received transfer, including transfer within Geomatrix.
