split-spoon samplers designed to hold 2" diameter metal sample <br /> tubes. While one core barrel was in use, the other was <br /> ' thoroughly cleaned with TSP & water, filled with new metal tubes <br /> & set aside pending use. <br /> ' <br /> Operations began at 0835; surface material consisted of road base <br /> & gravel, grading to brown clay loam. At a depth of 5' , the <br /> drill plug was retrieved, a clean core barrel was inserted into <br /> ' the flights, and driven from 5' to 616" . The core barrel was <br /> removed and laid on a clean surface for examination by the <br /> geologist. The barrel was carefully opened; recovery' was <br /> recorded, and the contents described in detail. A full tube of <br /> ' cored material was quickly examined & promptly covered with <br /> teflon tape & plastic caps; the ends were sealed with duct tape, <br /> the tube identified & placed on ice in a sealed chest for <br /> ' preservation. <br /> Drilling continued to 30' , at which depth another core was taken; <br /> it was handled in the same manner as above. Additional cores <br /> ' were taken at 15-16' 6" , 20' -21' 6", & 21' 6"-23..0" . The augers <br /> were advanced. to 32' , appronimatelp 10' below the mater table. <br /> Refer to PLAM V111 for details of blowy counts, core recovery, <br /> description of litholLogy, and other details. `Where was no <br /> evidence of contamination in drill cuttings, cored material, or <br /> groundwater. <br /> ' Drill cuttings and unused core material were Placed in metal <br /> drums, tightly sealed, labeled, & stored on site pending results <br /> of laboratory analysis. <br /> ' At the completion of auger.ing operations, 2" SCD. 40, flush <br /> screw-joint blank & shop perforated PVC was run in the hole to <br /> ' 32' and gravel packed & sealed as shown on PLATF 1X. <br /> Cementing of the annular space above the bentonite sear was <br /> deferred pending completion of the other well. The casing top <br /> ' & annulus were thoroughly covered. <br /> I <br /> A smaller auger rig capable of advancing flights with the mast <br /> laid down was mobilized over the location for well #4. It was <br /> equipped with clean 8 1/4" flights, which used the same core <br /> barrel assembly uhilised fox wall 45. However, instead of being <br /> pounded into the soil with a drive hammer, the coring assembly is <br /> ' pushed into the ground with a hydraulic piston. Blow counts <br /> cannot be obtained with this type of equipment- <br /> Operations began at 1035 as directed by the RG. Cores were taken <br /> from 51 -61,611 , 1011-1116", 151 -1616" , & 20121' 6" ; they were <br /> described, handled & preserved by the same WJH field procedures <br /> used for well 05. The well was advanced to 33' , preparatory to <br /> completing. Drill cuttings & unused core material was placed in <br /> 1 5 <br />
