The record sheet was signed, timed, and dated by the <br /> sampler when transferring the samples. Custody transfers were recorded <br /> for each individual sample; for example, if samples were split and sent to <br /> more than one laboratory, a chain-of-custody record sheet accompanied <br /> each sample. The number of custodians in the chain of possession were <br /> minimized. A copy of the Sampling and Analysis Chain-of-Custody Record <br />' was returned to EMCON Associates with the analytical results. <br />' Ground-water Sampling and Analysis Request Form <br /> A Ground-water Sampling and Analysis Request Form (see Figure D-4) or <br /> purchase order, or both, accompanied the samples delivered to each <br /> laboratory. These forms served as official communication to the laboratory <br /> of the particular analysis/analyses required for each sample. <br /> pj010f9010f90o020.1 ag D - g Rev. 0 December 15, 1992 <br /> 1 <br />
