• <br /> Portion of the core at 66' was screened with the PID meter; no <br /> response was noted_ The tube at 66' was sealed and preserved per <br /> standard field procedures described earlier. <br /> The hole was advanced to 70' , and the final core was taken from <br /> ' " Full recovery, (30" , ) consisted of blue clay and <br /> sandy brown clay, grading to dense, sticky plastic blue clay. <br /> The outside of the core barrel was wet, and water was noted when <br /> the brass tubes were removed. The was no evidence of contamina- <br /> tion either in the core material or the water; the PID meter read <br /> only background from a sample at 72' . The middle tube was sealed <br /> and preserved per WJH protocol. <br /> The decontaminated hydropunch tool was made up and lowered into <br /> the auger flights to bottom. It was driven from 72' 6" to 75' <br /> with a drive hammer; blow counts were 60--50-75. The tool was <br /> opened at 1330 hours and allowed to set for 30 minutes_ When the <br /> tool was retrxved, it contained approximately 1 liter of clear <br /> water grading to slightly muddy water. Four (4) clean glass <br /> VOA' s, preserved with HCL by Del-Tech, were filled from the <br /> sample chamber of the hydropunch tool. They were checked closely <br /> • to make sure there were no bubbles; after securely sealing and <br /> labeling the VOA' s, they were placed on ice pending transport to <br /> FGL laboratory. The bore hole was pressure grouted from bottom <br /> to the surface by pumping a cement slurry down the hole with a <br /> flexible hose. Drill cuttings and unused core material was <br /> Placed in steel drums, securely sealed, and stored on site <br /> pending laboratory results. <br /> The preserved soil & water samples were transported under chain <br /> of custody by Wm. Hunter to FGL Environmental laboratory with <br /> instructions to test for BTEX. & TPH-G. The results of those <br /> analyzes are summarized on copies of the labor- <br /> atory sheets & chain of custody are included as EXHIBIT I & J <br /> The lithologic log of the soil boring is included as ELATE Vi <br /> IARY OF SE5 NT WQRK DONE 10 DATE: <br /> 1. A 1 ,000 gallon UST which had contained gasoline was removed <br /> from the Normac property in July, 1989. Soil contamination was <br /> noted; spoil was returned to the hole. <br /> 2. In January, 1990, the site of the removed DST was re-entered, <br /> additional spoil was removed; it was successfully remediated on <br /> site & returned to the hole. <br /> 3. In October, 1990, five (5) soil borings were taken to 40' for <br />. the purpose of defining the plume which appeared to be present. <br /> 9 <br />
