w� <br /> ' name, address and telephone number, the employee number of the individual who <br /> performcd the sampling, the sample numbers, the date and time the samples were <br /> collected, the number of containers each sample occupies, and the analyses for which the <br /> samples are being submitted, if any. The chain-of-custody form is signed by each person <br /> who handles the samples, including all Kleinfeider employees and the receiving employee <br /> rW of the analytical laboratory when the samples are delivered. An example of the chain-of- <br /> custody form is attached to this appendix. <br /> B-2,6 Soil Sample Selection for Laboratory Analysis <br /> The selection of soil samples for laboratory analysis is based upon: 1) the project <br /> objectives and requirements, 2) qualitative field screening performed in the field using the <br /> organic vapor detector, and 3) field observations such as lithology, odor, discoloration, or <br /> high moisture content. Generally, samples are submitted from the bottom of the boring <br /> and from soil horizons with significant potential for contamination as indicated by the <br /> organic vapor detector, observations, and site history. Samples may be collected from <br /> regular intervals when information on concentrations versus depth is desired. Samples that <br /> - are not selected for laboratory analysis are held in sample control for pussibie future <br /> reference. When these samples are no Ionger needed,they are returned to the site and are <br /> combined with the soil cuttings generated during their collecdon. <br /> B-2.7 Soil Boring Closure and Soil Cutting Disposal <br /> Soil borings are closed immediately after the collection and logging of soil samples. <br /> Closure is accomplished by grouting the boring with a cement/bentonite slurry or as <br /> otherwise required. <br /> Drill cuttings will be placed in 55-gallon drums or wrapped in plastic and left onsite for <br /> disposal by the site owner. If requested, Kleinfelder can coordinate disposal of soil and <br /> water with contractors after chemical analysis results are available. <br /> B-3 GROUNDWATER MONITORING <br /> B-3.1 Monitoring Well Construction <br /> Construction details for shallow ground water monitoring wells are as follows: <br /> F6-FIELDPRO <br />
