Kennedy/Jenks Consultants <br /> Appendix A: Standard Operating Guideline - <br /> Boring and Subsurface Soil Sampling <br /> A.1 Introduction <br /> This guideline describes the equipment and procedures that are used by Kennedy/Jenks <br /> Consultants personnel for drilling and collecting soil samples. <br /> A.2 Equipment <br /> • Drill rigs and associated drilling and sampling equipment as specified in work plan: <br /> Hollow stem auger <br /> Mud rotary <br /> Reverse rotary <br /> • CME, 5 ft x 94 mm continuous-core barrels (hollow-stem auger) <br /> • 2.5-inch or 2.0-inch I.D. split-spoon drive sampler <br /> • 2.5-inch or 2.0-inch brass liners and sealing materials (plastic end caps, Teflon seals, silicon <br /> tape, zip-lock plastic bags) <br /> • Large capacity stainless steel borehole bailer <br /> • Sampler cleaning equipment <br /> Steamcleaner <br /> Generator <br /> Stiff-bristle brushes <br /> Buckets <br /> High purity phosphate-free liquid soap, such as Liquinox <br /> Deionized water <br /> Potable water <br /> • Insulated sample storage and shipping containers <br /> • Personal protective equipment (refer to project site safety plan) <br /> A.3 Typical Procedure <br /> 1. Obtain applicable drilling and well construction permits prior to mobilization. <br /> 2. Clear drilling locations for underground utilities and structures by Underground Service Alert <br /> (USA) and subcontractors. <br /> 3. Have all downhole equipment steamcleaned prior to drilling each boring. <br /> 4. Ensure that borings made to construct shallow monitoring wells are drilled with an auger drill rig <br /> that uses hollow stem augers of appropriate size to provide an annular space of a minimum of <br /> 2 inches between borehole wall and well casing. <br /> 5. Collect soil samples for lithologic logging purposes with a CME continuous coring system in <br /> 5-foot increments. <br /> 6. Collect soil samples for lithologic logging and chemical and physical analyses by driving a <br /> split-spoon drive sampler, in 2.5-to 5-foot increments, below the depth of the auger bit with a <br /> Monitoring Well Installation Work Plan, A-1 <br /> Barrel Ten Quarter Circle Land Company, Escalon, California <br /> f ;m(I sfIS-gFCuIDadmi p:03:C 07 ^7_h f;-109 cP .51m -ins,a �In'r,pP W�.i,'N adoc <br />
