at 0835; V & W Drilling Co_ rig, crew, and support truck were on location. A review of the area revealed that the ground was firm enough to support the rig, but the location of the well had to be moved slightly due to interference from an overhead power line_ The rig was equipped with clean, 5' lengths of 8 1/4" OD hollow- stem augers. After spotting the rig and raising the mast, operations commenced at 0850. From the surface to about 12' , the material consisted of pea gravel, (backfill material, ) which was penetrated easily. Evidence of water was noted at about 10' bgl; native material was encountered at 12' . At that point, an 18" California Modified split-spoon core barrel was assembled; it was filled with clean brass tubes. Both the core barrel and tubes had been thoroughly decontaminated prior to use. The core barrel was lowered into the augers, and driven from 12' to 13' 6" with a drive hammer; blow counts of 3-6-9. The core barrel was retrieved, laid on a clean surface, and carefully opened by the geologist. Recovery consisted of 18" of moist bluish-gray sticky clay, with occasional streaks of reddish colored material, (probably iron oxide. ) There was a 1 1/2" bed of moist brown silty clay in the bottom metal tube. No odors were noted, & there was no rainbow or sheen when a portion of the core was placed in water. Two tubes were preserved by covering the ends with teflon tape & plastic end caps & thoroughly sealing with duct tape. The tubes were properly labeled & placed on ice in a sealed chest pending transport to the laboratory. The augers were advanced to 25' ; drill cuttings consisted of tan to brown clay, with portions of sticky blue-gray clay. There were no odors or other evidence of contamination noted. Upon reaching the programmed depth, 2' , sch. 40, blank & slotted, screw-thread flush Joint PVC was made up and run inside the auger flights to bottom. The casing consisted of the following, from bottom up: Threaded bottom cap 20' (2 Jts. ) of slotted pipe - top at 5' bgl. 5' (1 jt. ) of blank casing - top at the surface. As the augers were slowly pulled up, the annular space between the open hole & the casing was filled with #3 SRI Supreme graded sand. A weighted tape was run in the hole to monitor fill, and the casing was continually vibrated to assure a uniform pack. The top of the sand was tagged at 3' bgl; it was capped with 1/2 bag of bentonite pellets - top at 2' - which was wetted with water. The annular space from the top of the bentonite to the surface was filled with a cement slurry which was mechanically mixed & poured into the hole. A precast traffic cover was firmly • grounted in place, with the casing extending far enough inside the box to allow the installation of an expandable locking cap. 5
