Kennedy/Jenks Consultants <br /> the rods will be driven another 4 feet or 5 feet. This process will be repeated until the desired <br /> depth is reached. <br /> 6. The soil samples will be retained for lithologic logging and chemical analyses, if appropriate. <br /> 7. The soils will be classified in the field in approximate accordance with the visual-manual <br /> procedure of the Unified Soil Classification System (ASTM D-2488-93), and the Munsell Color <br /> Classification. <br /> 8. If required, soil samples will be collected at selected intervals for laboratory analysis. At these <br /> intervals, the ends of one or more of the soil sample liners will be covered with Teflon end <br /> sheets and plastic end caps, and labeled. Labels will document the sample designation, type, <br /> date and time of collection, collector(s), location, and any additional information. <br /> 9. After sample collection, the boring will be grouted to ground surface with a neat cement grout <br /> (Type II Portland cement) using the tremie method. <br /> B.4 Equipment Cleaning <br /> 1. Downhole equipment(rods, sampler)will be cleaned prior to each borehole. <br /> 2. Sampling equipment(sampler)will be cleaned with a brush in a solution of high-purity <br /> phosphate-free soap and potable water, then rinsed with potable water followed by double <br /> rinsing with deionized water prior to each sampling run. <br /> 3. Downhole equipment and vehicles which warrant it, will be steam cleaned prior to leaving site at <br /> completion of sampling. <br /> 0.5 Investigation-Derived Residuals <br /> Soil cuttings will be placed in labeled 55-gallon DOT-approved drums with bolt-on covers. <br /> Decontamination water and groundwater residuals will be contained in labeled 55-gallon <br /> DOT-approved drums with bolt-on covers. All residuals generated during sampling activities will be <br /> removed from the site and disposed of according to appropriate regulations. <br /> Page 2 Soil Investigation Work Plan, <br /> BNSF Mormon Yard, Stockton, California <br /> A IisprouPlatlminyob11J1f]65020.�bnM09+epartslmiHnwsi-xvMplenbpp!_�YaP�+���� <br />
