A-6 <br /> • Analyses requested. <br /> • Sample condition and temperature. <br /> 4.1.5 Sample Transfer and Shipment <br /> Samples were always accompanied by a chain-of-custody record. When transferring samples, <br /> the individuals relinquishing and receiving the samples signed, dated, and noted the time on the <br /> chain-of-custody record. Samples were packaged properly for shipment and dispatched to the <br /> appropriate laboratory for analysis. The chain-of-custody record accompanied each shipment. <br /> The method of shipment, courier name(s), and other pertinent information was entered in the <br /> chain-of-custody record. <br /> 4.2 Laboratory Custody Procedures <br /> A designated sample custodian accepted custody of the shipped samples and verified that the <br /> information on the sample label matched that on the chain-of-custody record. Information <br /> regarding method of delivery and sample conditions was also checked on the chain-of-custody <br /> record. The custodian then entered the appropriate data into the laboratory sample tracking <br /> system. The laboratory custodian may have used the sample number on the sample label or may <br /> have assigned a unique laboratory number to each sample. The custodian then transferred the <br /> sample(s) to the proper analyst(s) or stored the sample(s) in the appropriate secure area. <br /> Laboratory personnel are responsible for the care and custody of samples from the time they are <br /> received until the sample is exhausted. Once at the laboratory, the samples are handled in <br /> accordance with U.S. Environmental Protection Agency SW-846,-Test Methods for Evaluating <br /> Solid Waste Physical/Chemical Methods, Third Edition, for the intended analyses. All data <br /> sheets, chromatographs, and laboratory records were filed as part of the permanent <br /> documentation. <br /> i <br /> 4.3 Corrections to Documentation <br /> Original data recorded in field notebooks, chain-of-custody records, and other forms were <br /> written in ink. These documents were not altered, destroyed, or discarded, even if they were <br /> illegible or contained inaccuracies that required a replacement document. <br /> If an error was made or found on a document, the individual making the corrections did so by <br /> crossing a single line through the error, entering the correct information, and initialing and <br /> dating the change. The erroneous information was obliterated. Any subsequent error(s) <br /> discovered on a document were corrected. All corrections were initialed and dated. <br /> LRPT026-MAF <br />
