r <br /> r <br /> APPENDIX E <br /> TYPICAL KLEINFELDER FIELD PROTOCOL <br /> 1 <br /> E-1 FIELD PREPARATION <br /> Before performing work in the field, environmental staff review the scope of work, <br /> r prepare a health and safety plan, coordinate the work to be done with their supervisor, <br /> assemble the necessary sample containers, and check, calibrate and clean equipment <br /> to be used in the field. When underground utilities may exist at a site where subsurface <br /> soil samples are being collected, USA Underground is contacted with the boring <br /> locations and the scheduled date of drilling, or a utility locating firm is employed to <br /> check the boring locations. <br /> rE-2 SURFACE AND SUBSURFACE SOIL SAMPLING <br /> rE-2.1 Sample Collection <br /> Surface soil samples are collected using a hand trowel, auger, or hardened metal <br /> sampler that is cleaned before and between samples. Subsurface soil samples are <br /> collected from soil borings using a hand auger and slidebar sampler. While advancing <br /> the borings, an experienced environmental geologist classifies the soil, logs the lithology <br /> and collects soil samples for laboratory analysis. <br /> E-2.2 Decontamination of Equipment <br /> To reduce the potential for cross-contamination, augers and associated equipment are <br /> cleaned prior to advancing each boring. In addition, sampling equipment is cleaned <br /> with a detergent wash and rinsed with distilled water prior to collecting each soil sample. <br /> 1 <br /> -2.3 Collection of Soil Samples <br /> Soil samples are collected at depths up to 5 feet for field screening, lithologic logging, <br /> and potential chemical analysis. Samples are collected by advancing the boring to a <br /> r <br /> 125819.E01/ST013R0732 Page E-1 December 11, 2013 <br /> Copyright 2013 Kleinfelder <br />
