be sealed. Pressure will be applied to the vessel with:a hand pump and the filtrate directed <br /> into the appropriate containers. Each filter will be used once and discarded. <br /> Sample Preservation and Handling <br /> The following section specifies sample containers, preservation methods, and sample <br /> handling procedures. <br /> Sample Containers and Preservation <br /> Sample containers vary with each type of analytical parameter. Container types and <br /> materials will be selected to be nonreactive with the particular analytical.parameter tested. <br /> Sample Handling <br /> Sample containers will be labeled prior to.sample collection. Samples will be kept cool <br /> with cold packs until received by the laboratory. Afihe time"of sampling, each sample ' <br /> will be logged on a chain-of-custody recordthat will accompany the sample to the <br /> laboratory. <br /> Samples that require overnight storage prior to shipping to the laboratory will be kept <br /> cool (4°C) in a refrigerator. The refrigerator is kept iii;a warehouse, which will be locked <br /> when not occupied by an IT employee. A sample/refrigerator log will be kept to record <br /> the date and time that samples are placed into and removed from the refrigerator. <br /> Samples will be transferred from .IT to a state-certified laboratory by courier or taken <br /> directly to th'e laboratory by the environmental sampler. Sample shipments from IT to <br /> laboratories performing the selected analyses routinely occurred within 24'hours of <br /> sample collection. <br /> I. <br /> Sample Documentation <br /> The following procedures will be used during sampling and analysis to provide <br /> chain-of-custody control during sample handling from'€collection through storage. Sample <br /> documentation included the use of the following: <br /> • Water sample field data sheets to document Chain-of-custody record sheets for <br /> sampling activities in the field documenting possession and transfer of <br /> samples <br /> • Labels to identify individual samples <br /> • Laboratory analysis request sheets for <br /> documenting analyses to be performed <br /> Sac1N:ICamPk\Data\ rcliive\Arco\54691Reportsl5469p103.doc-95Usg:1 ITCorporatioai <br /> B-4 02/28/00 <br /> i <br />
