i <br /> 8. Pull the split-barrel sampler out of the more hole and detach the sampler from [lie center rock. <br /> 9. Disassemble the sampler and separate the 3 liners from one ,another. <br /> 10. Take the bottom-most sample and place aluminum foil over each end and seal the end:: by <br /> placing end-caps on them. Use electrical tape to securely seal the end-caps to the liner, and <br /> lapel the sample using o permanent marker. <br /> '.1. Place a sample label on the sample liner and place the srunple in a cooler. <br /> illl If organic vapor analysis is to be perforated, the middle soil sample is used. Steps 12.a through <br /> 12.d discuss haw to prepare the soil sample for organic vapor analysis. <br /> 12.a. Remove the middle 6-inch sample liner from the split-barrel sampler and remove <br /> approximatelv:,ne inch of'soil material from one end. <br /> 12.1). Take a piece of alurttinum foil and seal the end of the lube that the soil was removed <br /> from as tightly as possible. Minimize the time that is spent between slops 11a and 12.1). <br /> 12.c, Allow the sample to sit in a warm place for two to five minutes to allow for volatilization <br /> of organic chemicals that may be present. <br /> 12.d. Insert the OVM (PID)sniffer tip through the aluminum foil and take a measurement <br /> (See SOP 9002 for OVM(PID)operating procedures). Record the reading on the field <br /> log. <br /> B. Place the upper sample liner and the middle sample liner tubes off to the side to be cleaned and <br /> decontaminated for future use. See SOP 7001 for procedures concerning equipment <br /> decontamination. <br /> 14. See SOP 8001 for post-sampling procedures concerning packaging and shipment of soil samples. <br /> QA/QC: <br /> Rubber nitrile gloves should be worn at all times to prevent contamination of and from the soil samples. <br /> Both the gloves and the brass liners should be decontaminated before initial use and between <br /> subsequent sampling(see SOP 7001 for proper decontamination procedures). The sample liners should <br /> be sealed tightly to prevent any loss of volatile constituents. <br /> REFERENCES: <br /> Driscoll, F. G., 1936.
