08 August 2012 AGE-NC Project No. 96-0254 Page 2 of 3 MW-7 and OW-1 through OW-10 were drilled-outto one foot deeperthan total depth using a CME-75 hollow stem auger drill rig equipped with 8.25-inch diameter hollow stem augers. Well MW-2A/B was drilled out using 10.25-inch diameter augers. All original well construction materials were removed(including well casing,screen,filter pack,and annular seal)to ensure that no residual contamination was sealed within the abandoned borehole; the majority of the shallow well casings were removed intact before advancing the augers beyond three feet below surface grade(bsg). Following over-drilling,each well was grouted to near surface using a Portland cement grout mixture, well boxes were removed and the surfaces at each location were completed with a rapid setting concrete mixture. Well MW-6 was drilled out to a depth of approximately three feet bsg; the well casing for MW-6 was removed intact. A 1-inch diameter PVC private water line was encountered at three feet bsg extending directly adjacent to the borehole of MW-6. The water line was damaged by drilling activities and was repaired on 15 May 2012. However, due to the location of the water line the well could not be over-drilled to total depth. At the direction of the EHD the top three feet of the borehole was grouted to the near surface and the surface was completed with concrete. Well construction materials and soil cuttings were placed in a soil bin for subsequent disposal. Two soil samples were collected from the soil bin on 16 May 2012 and sent to Cal Tech Environmental Laboratory (CTEL), a state-certified laboratory, for soil profiling analysis. The samples were composited and analyzed for total petroleum hydrocarbons as gasoline (TPH-g) in accordance with EPA method 8015-modified, benzene, toluene, ethylbenzene, and total xylenes (BTEX), five fuel oxygenates, ethylene dibromide (EDB) and 1,2-dichloroethane (DCA) in accordance with EPA method 82608 and total lead in accordance with EPA method 6010B.The analytical results indicated that all analytes were below detectable limits. On 06 June 2012,the soil was transported to Potrero Hills Landfill in Suisun,California,under non-hazardous waste manifest.The laboratory analytical report (CTEL Project Number CT214-1205119), quality assurance/quality control report, and chain-of-custody form are included in Appendix B. A copy of the non-hazardous waste manifest is included in Appendix C. Advanced GeoEm9ronmental,Inc.
