The preserved samples were transported under chain of custody to <br /> FGL Environmental laboratory with instructions to test for BTEX & <br /> TPH--G. <br /> The results of those analyzes are summarized on TABLES VI & II; <br /> all samples were below detection limits. Copies of the labora- <br /> tory reports & chain of custody are included as EXHIBITS I & J, <br /> PLAT$ IX is the lithologic plot of that soil boring. <br /> Drill cuttings & unused core material were placed in metal drums, <br /> securely sealed, and moved to the Normac site for storage. The <br /> auger rig was also moved to the Normac property and stored in a <br /> locked building for the weekend. <br /> Work resumed on January 17, 1994, under the direction of Wm, <br /> Hunter, RG, assisted by Don Light of Del-Tech. The same crew was <br /> used as on the previous borehole. The rig was mobilized on the <br /> spot previously marked by WJH; it is identified as TB-1 on PLATE <br /> VII . The auger flights, hydropunch, and associated equip ment <br /> had been thoroughly decontaminated prior to bringing on location. <br /> The PID meter was calibrated as before by Don Light, and wit- <br /> nessed by Mr. Hunter. <br /> • Operations commenced at 1030 hours; from surface to 20' the drill <br /> ]. <br /> cuttings consisted of tan to light brown clay, slightly moist, <br /> sticky & somewhat plastic. At 20' , the blanking plug was pulled, <br /> and a clean core barrel was inserted. A core was taken from 20' <br /> to 22' 6" ; recovery was 24" of brown to buff to gray clay, slighly <br /> Plastic, with a mottled appearance. No odors or evidence of <br /> discoloration were noted. A portion of core from 22' was placed <br /> in a sealed tube, allowed to stand for 10-15 minutes, and tested <br /> for contamination by inserting the probe of the PID meter into <br /> the plastic end cap. No reading was noted. The middle tube was <br /> promptly sealed, labeled, and preserved according to WHJ standard <br /> field procedures described earlier. <br /> Drilling continued as before, and a core was taken from 25' to <br /> 27,¢.. ; recovery consisted of 27" of brown to dark brown clay as <br /> above, with small inclusions of dark gray clay_ The PID meter <br /> reading was zero from a sample at 27' . no evidence of contamina- <br /> tion was noted, and the middle tube at 26' was sealed and pre- <br /> served as before. <br /> The next core was taken from 101 to 32' 6" ; recovery was 30" of <br /> dark gray, silty organic clay, grading to fine to medium grained <br /> sand. There was no response from the PID meter from a sample at <br /> 32' , and no odor or discoloration was noted_ The middle tube was <br /> sealed and preserved per WJH protocol . <br /> 7 <br />
