Sampling and Analysis Chain-of-Custody Record <br /> The chain-of-custody record will be initiated at the time of sampling, and contain at a <br /> minimum the sample designation (including the depth at which the sample was <br /> collected), sample type, analytical request, date of sampling, and the name of the sampler. <br /> The record sheet will be signed, timed, and dated by the sampler when transferring the <br /> samples to the laboratory or courier. The number of custodians in the chain of possession <br /> will be minimized. A copy of the chain-of-custody record will be returned with the <br /> analytical results. <br /> 4. Groundwater Sampling and Analysis Request Form <br /> A groundwater sampling and analysis request form will be used to communicate to the <br /> sampler the requirements of the monitoring event. At a minimum,the groundwater <br /> sampling and analysis request form will include the following information: <br /> • Date scheduled <br /> • Site-specific instructions <br /> • Specific analytical parameters <br /> • Well number <br /> • Well specifications (expected total depth, depth of water, and product thickness) <br /> Project Workplan A-5 SA1433 <br /> July 30,2004 n1sa01433\gw wiwp\workplan.doc <br />
