r <br /> r <br /> M <br /> were noted. The bottom tube was sealed & preserved in the same <br /> ' manner as the previous ones. <br /> The well was advanced to 101 ; drill cuttings consisted of brown <br /> clay & sandy clay - no odors noted. <br /> ' The interval 10' to 11'6" was cored using blow counts of 8-12-14; <br /> recovery was 12" of brown sandy clay, moist, very slightly <br /> plastic, with a mottled appearance. No odor or evidence of con- <br /> tamination was noted. The bottom tube was sealed and preserved <br /> as above. <br /> ' The augers were advanced to 15' ; cutting consisted primarily of <br /> brown, slightly plastic clay, with a slight petroleum odor. <br /> ' The interval 15' to 16' 6" was cored using blow counts of 8-11-11. <br /> When the core barrel was opened, a definite petroleum odor was <br /> detected. Recovery was 15" of brown mottled clay grading to <br /> r sandy clay & clayey sand. Some apparent discoloration was noted, <br /> possibly due to contamination. The bottom tube was sealed and <br /> preserved per standard procedures <br /> The well was advanced to 20' ; drill cuttings consisted of brown <br /> to gray sandy clay, with no detectable odor. <br /> ' The core barrel was driven from 20' to 21' 6" with blow counts of <br /> 5--8-13; recovery was 13" of brown to gray sandy clay, slightly <br /> sticky, with a mottled appearance. No odors were noted, but <br /> visual examination indicated some discoloration which may be due <br /> ' to contamination. A soil sample was sealed and preserved using <br /> standard procedures described earlier. <br /> ' The well was advanced to 22' , when a change in drilling rate <br /> indicated softer sediments had been penetrated. WJH decided to <br /> take a core at this point, since the water table had most likely <br /> been reached. <br /> A properly prepared core barrel was inserted into the flights, <br /> and was advanced from 22' 6" to 24' with blow counts of 22-29-38. <br /> Recovery consisted of 12" of soft, loose, fine to coarse-grained <br /> sand; a slight petroleum odor was detected, but no visible <br /> evidence of free product was noted. The bottom tube was sealed <br /> ' and preserved as above. <br /> The well was advanced to 33' ; drill cutting consisted of very <br /> ' wet, loose "water sand" ; when the auger flights were pulled, the <br /> bottom two sections were covered with very wet, coarse sand. <br /> 8 <br /> 1 <br />
