*ft/ properly licenced auger rig as directed by Mr. Hunter. Margaret Lagorio, Lead Sr. REHS, and Bruce Askanas, REHS, from the San Joaquin County EHD arrived at 0915 hours. After discussing field procedures, Ms. Lagorio directed that the well be placed in the southwest corner of the site where the UST's had been located. Refer to PLATE III & EXHIBIT F for it's location. The rig was equipped with 5' lengths of clean 6" OD augers; Robert Vickery was the driller, assisted by two helpers. Tools included a California Modified Split-spoon sample barrel designed to hold three, 2"x6" metal tubes. The rig was equipped with two barrels so that while one was in use the other one was being decontaminated by cleaning with an Alconox solution and double rinsed. Drilling began at 0930 hours; fill material was penetrated to approximately 12' where native soil was encountered. The first core was taken from 15'-16'6". It was retrieved and placed on a clean surface. The barrel was carefully opened and the metal sleeves laid out for examination and preserving. After describing the material, Mr. Hunter promptly preserved two sleeves by covering the ends with teflon tape& plastic caps and thoroughly sealing both ends with duct tape. The preserved tubes were labeled and placed on ice. A portion of the remaining core was placed in a ziplok bag, labeled, and set aside for 10-15 minutes. The probe of a field calibrated PID meter was then inserted into the bag and the reading recorded. The sample chamber was then thoroughly cleaned and set aside until needed. Cores were taken at 5 foot intervals from 15' bgl to 81'bgl; they were handled in the same manner as described above. Refer to PLATE VI for complete details of blow counts, core recovery, lithology, and PID readings. After taking the last core, 2", flush-screw joint PVC casing was made up and run in the augers. The bottom 20' consisted of 6 rows of.02" machine cut slots sealed with a threaded end cap. The remainder of the pipe was blank. SRI Supreme gravel was poured into the annular space between the casing and augers; the pipe was agitated during this stage to prevent voids in the gravel pack. The height of the gravel pack was continually monitored with a weighted tape. Auger flights were withdrawn as the work progressed. When the gravel had filled to a depth of 58', two feet above the top of the screen, it was sealed by pouring 1 112 sacks of bentonite into the annular space and wetting it with water. The remaining flights were withdrawn and the annulus was filled with a cementlbentonite mixture using a flexible hose and grout pump. A precast box and traffic cover were placed at the surface, and the top of the casing secured with an expandable cap. PLATE VII is a schematic showing well completion details. The preserved samples were transferred under chain of custody to Don Light of Del-Tech for later transfer to the courier for Sherwood Labs. All samples were to be analyzed for BTEX, TPHg, and TPHd. Bulk density, effective porosity, & organic carbon were be run 4
