Kennedy'Jenks Consultants <br /> Appendix B: Standard Operating Guideline - <br /> Typical Hydraulic Push/Drive Sampling <br /> Procedures <br /> B.1 Introduction <br /> This guideline describes the equipment and procedures typically used by Kennedy/Jenks <br /> Consultants personnel for collecting soil and reconnaissance groundwater samples with a hydraulic <br /> push/drive system. <br /> B.2 Equipment <br /> • Portable, hydraulic push/drive sampling system <br /> • 4-foot long or 5-foot long (depending on drive rod length), 1.75-inch O.D. acetate or butyrate <br /> liners (or other appropriate size for the push/drive rods)and liner sealing materials (Teflon <br /> sheets, plastic end caps, Ziploc plastic bags) <br /> • Type II Portland cement <br /> • Equipment cleaning materials <br /> Steam cleaner <br /> Generator <br /> Stiff-bristle brushes <br /> Buckets <br /> High-purity phosphate-free liquid soap <br /> Distilled or Deionized water <br /> Rinsate collection system <br /> • Personal protective equipment <br /> • Appropriate groundwater sample containers <br /> • Chain-of-custody forms <br /> • Insulated sample storage container and ice or ice substitute <br /> B.3 Typical Procedures <br /> 1. Applicable drilling permits will be obtained prior to mobilization. <br /> 2. Sample locations will be cleared for underground utilities. <br /> 3. All re-usable downhole equipment will be cleaned prior to use at each location. <br /> 4. Soil borings will be advanced using a portable, hydraulic push/drive sampling system that drives <br /> steel sampling rods into the ground to collect continuous soil cores. <br /> 5. As the sampling rods are advanced, the soil core will be collected in a 4-foot long or 5-foot long <br /> inner acetate or butyrate liner(the length matches the length of the steel drive rods), which is <br /> attached to lead rod. After being advanced 4 or 5 feet, the inner liner will be removed while <br /> leaving the steel rods in the borehole. A new liner will then be lowered back into steel rods and <br /> Soil Investigation Work Plan, Page 1 <br /> BNSF Mormon Yard, Stockton, California <br /> g:Yagr.W%Wmij.W 311365020.00_b=AOBapMst l4m -work-pl.*pb_mghydrpus�.d. <br />
