Labels <br /> Sample labels will contain the following information: <br /> Project number <br /> Sample number (i.e., well designation) <br /> Sampler's initials <br /> Date and time of collection <br /> Type of preservative used (if any) <br /> Sampling and Analysis Chain-of-Custody Record <br /> The Sampling and Analysis Chain-of-Custody Record (see Figure A-3) initiated at the <br /> time of sampling contains (but is not limited to) the well number, sample type, analytical <br /> request, date of sampling, and the name of the sampler. The record sheet will be signed, <br /> timed, and dated by the sampler when transferring the samples. Custody transfers will be <br /> recorded for each individual sample. For example, if samples are split and sent to more <br /> than one laboratory, a chain-of-custody record sheet will accompany each sample. The <br /> number of custodians in the chain-of-custody will be kept to a minimum. A copy of the <br /> Sampling and Analysis Chain-of-Custody Record is returned to EMCON with the <br /> analytical results. <br /> Groundwater Sampling and Analysis Request Form <br /> A Groundwater Sampling and Analysis Request Form (see Figure A-4) and/or purchase <br /> order will accompany the samples delivered to each laboratory. These forms serve as <br /> official communication to the laboratory of the particular analysis/analyses required for <br /> each sample. <br /> At minimum, the Groundwater Sampling and Analysis Request Form includes the <br /> following information: <br /> Date submitted <br /> Specific analytical parameters <br /> Well number <br /> Sample source <br /> SAC/pjM939\09390040.8e1-95 ifc:3 A-7 Rev.0 February 14, 1995 <br />
