water, no odor or sheen was noted Two preserved VOA' s were <br /> filled & tightly sealed; they were labeled & placed on ice in the <br /> container holding the preserved soil tubes Refer to PLATE X for <br /> a complete description of blow counts, core recovery, lithology, <br /> & other pertinent information The hole was covered pending <br /> grouting <br /> The rig was then moved to the spot marked for soil boring #2 , <br /> (see PLATE VI, ) and drilling began at 1410 hours using clean <br /> augers Cores were taken from 5 ' -61611 , 10 ' -11 ' 6" , and 151 -16 ' 0" <br /> using the same field procedures described earlier After <br /> retrieving the last core, a clean teflon bailer was run to 16 ' <br /> When it was retrieved, it contained 30" of muddy water Two <br /> preserved VOA' s were filled, tightly sealed and labeled & placed <br /> in the ice chest Upon standing for several minutes, the water <br /> in the VOA became quite clear The hole was covered pending <br /> grouting Refer to PLATE XI for a complete description of blow <br /> counts, core recovery, lithology, an other pertinent details <br /> The rig was then moved to the location marked for soil boring ##1, <br /> as shown on PLATE VI Drilling commenced at 1505 hours using <br /> clean auger flights Cores were taken from 5 ' -616" , 101 -11 ' 6" , & <br /> 151 -16 ' 61T using standard WJH field protocol After the last core <br /> was retrieved, a clean teflon bailer was run in the hole & <br /> allowed to set for 5-10 minutes When it was recovered, it <br /> contained about 30" of muddy water which had a petroleum odor <br /> Two VOA' s were filled, sealed, labeled, and placed on ice Refer <br /> to PLATE XII for details of blow counts, core recovery, <br /> lithology, and other data <br /> While completing the last soil boring, a cement/bentonite slurry <br /> was mixed in a mechanical blender Each soil boring was filled <br /> from the bottom to the surface by use of a tremae pipe & flexible <br /> hose The annular space between the 2" casing and hole in each <br /> monitoring well was also thoroughly grouted Preformed vaults <br /> were then installed on each well, with the casing extending far <br /> enough into the vault to allow the installation of a locking cap <br /> The casings were notched on the north side to facilitate future <br /> measurements The vaults were thoroughly cemented in place with <br /> a sand/cement mixture, and traffic covers installed The <br /> grouting operations were witnessed by Linda Turkatte of the San <br /> Joaquin County EHD <br /> The drums containing drill cuttings were clearly labeled and <br /> stored on site pending results of the laboratory analyses <br /> The preserved soil & water samples were transported under chain <br /> of custody by Wm Hunter to FGL Environmental laboratory in <br /> 8 <br /> I <br />
