If the sample is pushed <br /> rather than driven, be sure to record the push force. <br /> r t 7. Have the soils classified in the field in approximate accordance with the visual-manual <br /> i procedure of the Unified Soil Classification System (ASTM D-2488-90) and the Munsell Color <br /> Classification. <br /> ? 8. Prior to each sampling event, wash the split-spoon drive sampler and brass liners with high <br /> purity phosphate-free soap, and rinse them with potable water. <br /> 9. At each sampling interval, collect soil in one brass liner for potential laboratory analysis. Cover <br /> this sample in Teflon sheets, seal it with plastic caps, and wrap it with silicon tape. Place a <br /> completed sample label on the brass liner. Then see that the samples are placed in appropriate <br /> containers and stored at approximately 4°C. <br /> 10. Complete chain-of-custody forms in the field and transport the samples in insulated containers, <br /> at an internal temperature of approximately 4 °C, to the selected laboratory. <br /> , I <br /> Equipment Cleaning <br /> 1.
