• The hole was advanced to 50' , and _Was_cored from 50' to 52' . Recovery was 18" of tan to buff clay as above No odor noted, but the PID meter read 3 ppm. Preserved bottom sample as above After augering to 60' ,a core was taken from 64 ' to 62' ; recovery was 24" of tan to buff silty clay as described above. Again, no odor was noted, but the PID meter gave a reading of 8 ppm. The sample at 61' was sealed and preserved. The auger flights were advanced to 70' , where a drilling break indicated a lithology change A core was tak on-fx9m7Q'_ which consisted of 24" of tan to buff to gray, soft, friable water sand. No odor could be detected, but a sample recorded a reading of 26 ppm on the PTD meter. The middle metal tube was sealed and preserved per standard procedure, The hole was advanced to 82' ; when the flights were removed, the bottom 10--12' of the fins were covered with soft, loose water sand. Refer to EXHIBIT VIII for more details of the lithology. • The hole was opened to 10 1/4" and 4" blank and slotted PVC casing was run, sand packed, & sealed with bentonite as detailed on EXHIBIT XII . While casing was being run, MW #1 was grouted to within 2 feet of the surface by the method described previously The top of the casing was covered , and the rig was moved to MO ITO ING WE #3; it was agreed that grouting the annulus would be delayed until MW-3 was finished. The augers had been steamcleaned while MW-2 was being enlarged for running casing. Flights were advanced to 10' ; drill cuttings were black loam grading to tan to buff clay, similar to that encountered in the other wells A clean, properly prepared sample barrel was placed in the well, and a core was taken from 10' to 12' . Recovery wa 24" of tan to buff soft silty clay. A possible sweet odor was detected when the barrel was opened, but no reading was recorded when a portion of the core was tested with the PID meter. The middle sample was sealed and preserved per standard field procedures described earlier. The well was advanced to 20 ' ; cuttings consisted of tan to buff silty clay; no odor was noted. A clean sample chamber was introduced into the auger flights, and was cored from 20' to 22' . Recovery was 24" of tan to brown sandy, silty clay, grading to sandier clay & clayey sand. A faint odor was noticed, but no reading was measured with the PID meter. The sample at. 21 ' was preserved. 12
