Sampling and Analysis Chain-of-Custody Record <br /> The chain-of-custody record initiated at the time of sampling contained, at a minimum, <br /> the sample designation (including the depth at which the sample was collected), sample <br /> type, analytical request, date of sampling, and the name of the sampler. The record sheet <br /> was signed, timed, and dated by the sampler when transferring the samples. The number <br /> of custodians in the chain of possession was minimized. A copy of the chain-of-custody <br /> record was returned to Pinnacle with the analytical results. <br /> Groundwater Sampling and Analysis Request Form <br /> A groundwater sampling and analysis request form (see Figure A-3) was used to <br /> communicate to the environmental sampler the requirements of the monitoring event. At <br /> a minimum, the groundwater sampling and analysis request form included the following <br /> information: <br /> Date scheduled G Well number <br /> Site-specific instructions 0 Well specifications (expected total depth, <br /> � Specific analytical parameters depth of water, and product thickness) <br /> . <br /> CP1E:1TEICHERT STOCKTON\QTRLYISTKNQ199.DOC-95 Isg:1 A-6 � � <br />
