performed 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 <br /> the samples are being submitted, if any. Each person who handles the samples, <br /> including all Kleinfelder employees and the receiving employee of the analytical <br /> laboratory when the samples are delivered signs the chain-of-custody form. <br /> E-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 <br /> the organic vapor detector and/or XRF gun, and 3) field observations such as lithology, <br /> odor, discoloration, or high moisture content. Generally, samples are submitted from <br /> the bottom of the boring and from soil horizons with significant potential for <br /> contamination as indicated by the organic vapor detector, observations, and site history. <br /> Samples may be collected from regular intervals when information on concentrations <br /> versus depth is desired. Samples that are not selected for laboratory analysis are held <br /> in sample control for possible future reference. When these samples are no longer <br /> needed, they are returned to the site and are combined with the soil cuttings generated <br /> during their collection. <br /> E-2.7 Soil Boring Closure and Soil Cutting Disposal <br /> d immediate) after the collection and logging of soil samples. <br /> Soil borings are close y gg g p <br /> Closure will be accomplished by placing drill cuttings back into boring and filling with soil <br /> as needed. <br /> 125819.E01/ST013RO732 Page E-3 December 11, 2013 <br /> Copyright 2013 Kleinfelder <br />
