Sample Handling <br /> ' Sample containers were labeled immediately following collection. Samples <br /> were kept cool with cold packs until received by the laboratory. Cold packs <br /> ' were replaced each day to maintain refrigeration. At the time of sampling, <br /> each sample was logged on a Chain-of-Custody Record that accompanied <br /> the sample to the laboratory. <br /> Samples were transferred from the site to a state-certified laboratory by the <br /> sampling team. Sample shipment from EMCON Associates to laboratories <br /> 1 performing the selected analyses routinely occurred within 24 hours of <br /> sample receipt. The laboratory manager checked the holding times for <br /> requested analyses so that they were not exceeded. <br /> Sample Documentation <br /> The following procedures were used during sampling and analysis to <br /> provide chain-of-custody control during sample handling from collection <br /> through storage. Sample documentation included the use of the following: <br /> C field logbook to document sampling activities in the field <br /> C labels to identify individual samples <br /> C chain-of-custody record sheets for documenting possession <br /> and transfer of samples <br />' o laboratory analysis request sheets for documenting <br /> analyses to be performed <br /> Field Logbook <br /> In the field, the sampler recorded the following information on the Water <br /> Sample Field Data Sheet (see Figure D-2) for each sample collected: <br /> C project number <br />' C client's name <br /> 4 location <br />' C name of sampler <br /> U date and time <br />' C well accessibility and integrity. <br /> G pertinent well data (e.g., casing diameter, depth to water, <br /> well depth) <br /> pjOV9010000020.1 ag D - 5 Rev. 0 December 15, 1992 <br />
