Type II Work Plan - Addendum <br />UXO Construction Activities and Soil Removal Action <br />Preliminary Assessment/Site Investigation Update <br />California Anny National Guard Facility <br />Stockton, California <br />Contract No. GS-00E-007L/Task Order W91238-05-F-0084 <br />Version 2.0 <br />7.0 SAMPLE HANDLING PROCEDURES <br />All sampling activities will be recorded in the Field Notebook. The following <br />information will be recorded each time a sample is collected: (1) sample location, (2) <br />sample depth, (3) visual characteristics of the sample, and (4) any other relevant field <br />information. <br />Soil samples will be placed in laboratory-provided glass containers with Teflon® lined <br />lids, or contained in two-inch diameter brass or acrylic tubes with Teflon tape and plastic <br />end caps. Samples will be collected using clean stainless steel sampling tools. If soil <br />from several locations must be composited to provide sufficient sample volume for a <br />particular analysis, the sample may be composited and homogenized in a stainless steel <br />bowl using a stainless steel trowel or scoop. The sample will then be transferred into the <br />appropriate sample container, sealed, labeled, and place in an iced cooler held at a <br />temperature below 4° C. Sample compositing may be requested of the analytical <br />laboratory. <br />Sample Containers <br />Sample containers will be provided by the laboratory, pre-cleaned to EPA specifications <br />for the constituents of concern, and stored in clean areas prior to use. <br />Sample Volumes, Container Types, and Preservation Requirements <br />Sample container types, preservation requirements, and holding times for the analytical <br />methods to be performed on the soil samples are listed in Table 3. Samples not <br />preserved or analyzed in accordance with these requirements will be re-sampled and <br />analyzed. <br />Table 3 <br />Requirements for Soil Samples <br />Containers. Preservation.
