AQ a <br /> KLEINFELDER <br /> SAMPLING PROTOCOL <br /> This section describes the sampling, chain-of-custody, and analysis procedures of <br /> Kleinfelder. The type and locations of samples to be collected and the analyses to be <br /> performed are described in the text of this document. The sample collection and handling <br /> protocol that will be followed is detailed in this appendix. Analytical procedures and <br /> protocol are described in Appendix C. <br /> B-1 FIELD PREPARATION <br /> Before sampling in the field, environmental staff review the scope of work, prepare a <br /> health and safety plan, coordinate the work to be done with their supervisor, assemble the <br /> necessary sample containers, and check, calibrate and clean equipment to be used in the <br /> field. When underground utilities may exist at a site where subsurface soil samples are <br /> being collected, USA Underground is contacted with the boring locations and the <br /> scheduled date of drilling, or a utility locating firm is employed to check the boring <br /> locations. <br /> B-2 SUBSURFACE SOIL SAMPLING <br /> B-2.1 DRILLING <br /> Subsurface soil samples are collected from soil borings. Soil borings are advanced using a <br /> truck-mounted drill rig, equipped with 8-inch hollow stem augers. The borings can be <br /> advanced vertically, or at an angle up to 45 degrees from vertical. During drilling, an <br /> experienced environmental geologist classifies the soil, logs the lithology and collects soil <br /> samples for laboratory analysis. A sample boring log form is attached at the end of this <br /> appendix. <br /> C7-90-99 B-1 <br />
