• <br /> flights, and a core was en om 60 ' to 620 ; recovery <br /> consisted of 24" of tan to buff silty clay, dense, firm, with a <br /> mottled gray appearance. There was no odor noted, but a PID <br /> reading recorded 14 ppm. A sample was sealed and preserved as <br /> described earlier. <br /> The well was advanced to 70' ; drill cuttings were tan to buff <br /> clay as above. -Tb&_hole was cored from 70' to 72',; recovery <br /> consisted of 18" of very fine micaceous silty water sand, <br /> buff to tan, with a slight petroleum odor. A reading of 97 ppm <br /> was recorded with the PID meter. The bottom tube was sealed and <br /> Preserved using standard field procedures <br /> The hole was taken to 81' ; sediments consisted of soft, loose, <br /> water sand. EXHIBIT VII is a lithologic plot of the hole. <br /> The auger flights were pulled, and the hole enlarged to 10 1/4" <br /> for placing the casing. Blank & perforated threaded flush-joint <br /> 4" OD, sch. 40 casing was run, sand packed and sealed as shown <br /> on schematic diagram FjXHIBIT XI . The top of the casing was <br /> covered, and operations ceased for the day The preserved <br /> • samples were stored under refrigeration for future transfer to <br /> the laboratory. <br /> Ma-26. Xa93 - The rig was moved and spotted on the location <br /> marked for MONITORI G WELL #2; clean 8 1/4" augers were advanced <br /> to 10' ; cutting consisted of black peaty loam and tan to brown <br /> clay. A core was taken from 10„'_,. to 12' using the same method as <br /> described earlier. Recovery was 24" of tan to buff, silty, <br /> plastic clay. No odors or staining were noted, and no PID <br /> reading was taken The sample at 11' was sealed and preserved. <br /> The augers were advanced to 20' ; drill cuttings were tan to buff, <br /> slightly sticky clay. A core was taken from 20' to 2?' ; recovery <br /> was 24" of tan to buff, silty clay; moist, soft. There was no <br /> odor, and the PID meter did not give a positive reading. The <br /> sample at 21 ' was sealed and preserved per standard protocol. <br /> After angering to 30' , a core was taken from 30' to 32' ; <br /> recovery was 24" of buff to tan, silty, crumbly clay; slightly <br /> moist with a mottled appearance. There were no odors detected, <br /> but a reading of 11 ppm was measured with the PID meter. The <br /> sample at 31' was sealed and preserved as above. <br /> Augers were advanced to 40 ' , and a core w ' to <br /> A-2-!; recovery was 24" of tan to buff, silty micaceous clay as <br /> last above. There was no odor, but the PID meter gave a reading <br />. of 12 ppm. The middle tube was sealed and preserved <br /> 11 <br />
