samples, indicating it was near the edge of the plume . See TABLE <br /> III for a summary of those analyses . <br /> The probe unit was mobilized on location B-4 as shown on PLATE <br /> III . A soil sample was taken from 10 ' -1116" as described <br /> earlier; recovery was 1511 of gray-green to black, silty clay <br /> loam; no odor was detected. One of the metal sleeves was sealed, <br /> labeled, and taken to the onsite lab . <br /> The hydropunch tool was pushed to 15 ' bgl and opened. After <br /> setting for 30 minutes, a bailer was run - it came up dry. The <br /> hole was then deepened to 18 ' bgl, and a section of blank and <br /> slotted screen was lowered in the hole and allowed to set . <br /> See PLATE Vf for more complete details . <br /> The probe truck was moved to location B-2 (PLATE III, ) and the <br /> core barrel was driven from 101 -1116" . Recovery was 15" of tan <br /> to light brown sandy clay . It was fairly soft, but not wet ; no <br /> odor was noted. One sleeve was promptly sealed and taken to the <br /> onsite lab for analysis . <br /> The hydropunch tool was driven to 151 bgl, and opened. There was <br /> good water entry, and three VOA' s were quickly filled with muddy <br /> water containing considerable silt . No odor was noted; the VOA' s <br /> were taken directly to the laboratory for analysis . More details <br /> are given on PLATE Vg. <br /> After standing for one (1) hour, a bailer was run inside the <br /> screen placed in B-4 , but there was still no water entry. The <br /> screen was removed and the hole covered with a metal plate . <br /> The probe unit was then mobilized on the spot marked for B-3, <br /> (see PLATE III . ) In order to make sure that a water sample could <br /> be obtained, the hydropunch tool was pushed to 17 ' bgl & opened. <br /> Water entered very slowly - it took 15 minutes to fill two (2) <br /> VOA' s of muddy water; a very faint odor was noted. The VOA' s <br /> were sealed and taken to the onsite lab. <br /> The probe unit then moved about one foot (11 ) to the northwest <br /> and the split-spoon sample barrel was pushed & driven to 10 ' bgl . <br /> The tool was opened and driven to 1116" . When retrieved and <br /> opened, it contained 1211 of dark gray-green silty, clayey sand <br /> and silty clay. A faint petroleum odor was noted. One sleeve <br /> was promptly sealed and taken to the onsite lab for analysis . <br /> Refer to PLATE Vh for the lithologic plot . <br /> After completion of the above work, all probe holes were <br /> thoroughly grouted with cement as directed by Mr. Sasson of the <br /> 6 <br />
