If the sample is pushed <br /> rather than driven, be sure to record the push force. <br /> 7. Have the soils classified in the field in approximate accordance with the visual-manual <br /> 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 double-rinse them with deionized 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 /> 11. If applicable, as described in the site safety plan, use an OVA to analyze in situ air samples <br /> from the breathing zone, the inside of the augers or casing, and other locations as necessary. <br /> AA Equipment Cleaning <br /> 1. Prior to drilling each boring, steamclean downhole equipment (augers, well casing, sampler). <br /> 2. Before collection of each drilling sample, steamclean or wash sampling equipment (sampler and <br /> brass liners) with a brush, in a solution of high purity phosphate-free soap and potable water. <br /> Rinse the equipment with potable water and methanol and/or 0.1 N nitric acid, as appropriate. <br /> Follow this with double-rinsing using distilled water. <br /> 3. Before leaving the site at completion of drilling, steamclean downhole equipment and vehicles <br /> that require cleaning. <br /> A.5 Investigation-Derived Residuals <br /> Place soil cuttings and other residuals on the ground at Barrel Ten for disposition by the client. <br /> Place residuals in a manner that does not affect work site safety. <br /> Monitoring Well Installation Work Plan, A-2 <br /> Barrel Ten Quarter Circle Land Company, Escalon, California <br /> \\sfo\groupslis-group\adminyob\03\030118.27 btgctcl09-repottslmw-install-wpinlappendixlapp_a.doc <br />
