the lab under custody chain for analysis . <br /> The rig was then mobilized on the site marked A-5 as shown on <br /> PLATE III, and a core was taken from 101 -111611 as described <br /> above . Recovery was 15" of tan to brown silty clay, slightly <br /> moist but not wet . Soil had a mottled appearance due to color <br /> changes . A very faint fleeting unidentifiable odor was noted, <br /> which quickly dissipated. One of the metal sleeves was promptly <br /> sealed and taken to the onsite lab. The lithologic plot is <br /> included as PLATE Vd. <br /> The hydropunch tool was driven to 15 ' bgl, and opened to allow <br /> fluid entry. Several runs with the bailer produced no water; the <br /> tool was allowed to set for one hour, but there was no fluid <br /> entry. The tools were removed and thoroughly decontaminated <br /> prior to next use . <br /> Due to impending darkness, and after discussion with the County <br /> representative, it was decided to move to location C-2, (see <br /> PLATE III, ) in an attempt to define the limits to the north & <br /> northeast . After mobilizing the rig and cleaning equipment, a <br /> core was taken from 10 ' -11' 6" as described earlier. Recovery <br /> • consisted of 15" of dark gray to black silty clay loam, damp but <br /> not wet . An odor of "old" gasoline was noted in the core <br /> material, but no visable evidence of contamination was noted. <br /> One of the metal sleeves was promptly sealed and taken to the <br /> onsite lab for analysis . Refer to PLATE Ve for the lithologic <br /> plot . <br /> The hydropunch tool was driven to 15 ' bgl, and opened. Fluid <br /> entry was almost immediate, and three VOA' s were filled with dark <br /> colored water which had a definite "old" gasoline odor. Upon <br /> standing a few minutes, the water became clear and considerable <br /> fine gray silt settled to the bottom of the VOA' s . They were <br /> delivered to the onsite lab for analysis . <br /> All of the probe holes were thoroughly grouted with cement by the <br /> use of a small diameter flexible hose which was lowered to the <br /> bottom. After cleaning equipment, operations ceased for the day <br /> On November 28, 1995 , the Strataprobe unit and mobile laboratory <br /> were mobilized on location at 8 : 30 AM under the direction of Wm. <br /> Hunter, RG, from Wm. J. Hunter & Associates, (WJH. ) The results <br /> of the laboratory analyses of the prior days work revealed that <br /> locations A-1 & A-2 had no soil or water contamination, and that <br /> the soil from A-5 was clean; (there was no water entry from that <br /> hole. ) A-4 revealed significant levels of BTEX & TPHg in both <br /> • soil & water samples . C-2 revealed only TPHg in soil & water <br /> 5 <br />
