APPENDIX B <br /> KLEINFELDER FIELD PROTOCOL <br /> B-1 FIELD PREPARAI10N <br /> Before performing work in the field, environmental start review the scope of work,prepare <br /> a health and safety plan, coordinate the work to be done with their supervisor, assemble <br /> the necessary sample containers, and check, calibrate and clean equipment to be used in <br /> the field. When underground utilities may exist at a site where subsurface soil samples are <br /> the <br /> being collected, USA Underground is locating <br /> drIn is employed�oloheck the boring <br /> scheduled date of drillincations and the <br /> g, or a utility g <br /> )ocatlons. <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 /> B-2.2 Decontamination of Equipment <br /> To reduce the potential for cross-contamination, augers and associated equipment are <br /> steam cleaned prior to drilling each boring. In addition, sampling equipment is cleaned <br /> with a trisodium phosphate wash and rinsed with distilled water prior to collecting each soil <br /> sample. <br /> B-2.3 Collection of Soil Samples <br /> Soil samples are collected approximately every s feet for field screening,ltthologic logging, <br /> les are collected by advancing the boring to a point <br /> and potential chemical analysis.
