' PROTOCOL GEOMATRIX <br /> DRILLING AND DESTRUCTION OF SOIL BORINGS <br /> 1.0 INTRODUCTION <br /> This protocol describes the procedures to be followed during drilling and destruction of soil <br /> borings. The soil borings will provide information about geologic conditions, soil engineering <br /> ' properties, and/or soil quality. If the soil boring is utilized for well installation, the well will <br /> be installed in accordance with the protocol INSTALLATION OF WELLS. <br /> The procedures presented herein are intended to be of general use and may be supplemented <br /> ' by a work plan and/or health and safety plan. As the work progresses and if warranted, <br /> ' appropriate revisions may be made by the project manager. Detailed procedures in this <br /> protocol may be superseded by applicable regulatory requirements. <br /> ' If required, permits for drilling of soil borings will be acquired from the appropriate agency(s) <br /> ' before drilling is initiated, and an underground utility check will be conducted before drilling <br /> begins. An underground utility check will, at a minimum, consist of contacting a local utility <br /> talert service, if available. <br /> ' 2.0 DRILLING <br /> ' A DAILY FIELD RECORD will be completed for each day of fieldwork, and the original will <br /> ' be kept in the project files. <br /> ' The soil borings will be drilled using rotary, hollow stem auger. direct-push. or other <br /> appropriate method. In all rotary borings. compressed air will be filtered to remove oils <br /> before being circulated into the borehole. In mud rotary borings, appropriate drilling fluid <br /> additives, such as bentonite, will be used to maintain an open hole and to carni cuttings to-the <br /> ' DRILLING ;,ND DESTRUCTION OF SOIL 30RINGS ?see ; or 5 <br /> ' '.11c=a0r0-00 7%7, RE,TSNON DA7E: '.i.ARC.i ;Ow, DD-_ <br />
