When coring had reached approximately 3-feet, observed a slight sheen, odor and small black globules coming back with the wash water. The sheen, odor and globules were not observed below 3-feet during core attempt C When the core barrel was inserted for an additional core attempt, the barrel stopped at about 3-feet. The driller pulled back the core barrel to approximately 29.-feet and when the barrel was set back down it stopped at about 29.-feet. The core barrel was advanced with water and spinning to about 3.-feet. At about 3-feet a sheen, odor and black blebs were observed coming up with the wash water. When pressure was applied to the core barrel at approximately 3.-feet the water line appeared to jam up and the driller indicated he could not safely continue coring as it would cause the water line to burst. The driller indicated the borehole was not staying open enough below the casing to core. 12. The borehole was completed by backfilling with bentonite chips before the casing was removed. GZ-3
