Li <br /> APPENDIX B <br /> PROTOCOL FOR ADVANCING, SAMPLING, AND BACKFILLING <br /> OF SOIL BORINGS <br /> 1.0 INTRODUCTION <br /> This protocol describes the procedures to be followed during the advancing and logging of soil <br /> borings. The procedures presented herein are intended to`be of a general use.. As the work <br /> progresses and, if warranted, appropriate revisions will be made and approved in writing by the <br /> project manager. <br /> 2.0 ADVANCING <br /> The soil borings will be advanced using the Geoprobe direct-push method. The specific depths <br /> of the soil borings are presented in the workplan. The B&R field geologist or engineer will <br /> specify to the rig operator the maximum penetration rate; the depth of soil sample collection, <br /> method of sample retrieval, and other matters pertaining to the satisfactory completion of the <br /> borings. All unused soil samples and fluids generated during advancement and sampling of soil <br /> borings will be containerized and stored or disposed of in accordance with appropriate legal <br /> requirements. <br /> The tool string, hoses, and other components in which fluids and cuttings circulate, drive <br /> samplers, and probe tips will be thoroughly steam cleaned before and after installing each <br /> boring. Only clean water from a municipal supply will be`used.for decontamination of boring <br /> equipment. <br /> 3.0 SAMPLING AND LOGGING <br /> Discrete or continuous cores of drive samples will be obtained, evaluated, and retained. A <br /> detailed log of these samples will be made. <br /> B — I DA98117TROTOC:OLMM <br /> BOYARAN & ROSS, INC. <br /> Environmental Scientists & Engineers <br />
