The well was advanced to 30 ' , (drill cuttings as above, ) and a <br /> co_.. r.�_w.Mra_taken, from 30' to 32' . Recovery was 24" of tan to buff, <br /> silty micaceous clay; moist, friable, with occassional white <br /> streaks of what appeared to be gypsum No odors were noted, and <br /> the PID meter read zero. The middle sample was preserved. <br /> After drilling to 40' , the well 11as cg_f rq <br /> recovery was 24" of moist, pliable tan to buff clay_ No odor or <br /> PID reading was observed The middle sample at 41 ' was <br /> preserved. <br /> Drilling continued to 50' ; cuttings were tan to buff clay as <br /> above A core was taken from 50 ' to 52' , recovery was 24" of tan <br /> to buff clay as in previous core, but not as moist No odor was <br /> detected, but a PID reading of 2 ppm was measured from the top <br /> portion of the core. The middle sample was sealed and preserved <br /> as described earlier. <br /> The auger flights were advanced to 60' ; cuttings were same as <br /> above. Tie hole was cored from 60 ' to 62' ; recovery was 24" of <br /> tan to buff silty clay as above. No odor was noted, but the PID <br /> • meter gave a reading of 9 ppm. Again, the middle sample was <br /> presevered for later analysis <br /> The well was advanced to 70' , when the penetration rate indicated <br /> a change in lithology. A clean sample chamber was lowered into <br /> the augers, ands corp was taken from 70 ' to 72' . Recovery was <br /> 24" of tan to buff silty clay, laminated with fine gray sand with <br /> a mottled appearance. There was no noticeable odor or discolor- <br /> ation, but the PID meter registered 1.64 ppm_ The middle core <br /> sample was preserved. Because solid sand had not been encount- <br /> ered, the geologist decided to auger 5 feet, and take another <br /> core <br /> The hole was advanced to 77' , and was cored-from 77 ' to 79'_� <br /> Recovery was 24" of tan to buff medium grained loose water sand. <br /> A definite petroleum odor was detected when the barrel was <br /> opened, and a sample measured 164 ppm on the PID meter. The well <br /> was advanced to 85' preparatory to completing. Refer to EXHIBIT <br /> IX for the lithologic log of the well <br /> After removing the 8 1/4" flights, the hole was enlarged to 10 <br /> 1/4" , and 4" PVC was run, to 85, with 20 ' of screen on the bottom <br /> and the rest blank. EXHIBIT XIII gives details of the well <br /> completion. Both MW--2 & MW-3 were then grouted to the surface as <br /> described previously. <br /> The preserved soil samples were transported to Sherwood labora- <br /> 13 <br />
