t <br /> i <br /> r <br /> 22 March 2010 <br /> AGE-NC Project No. 98-0440 <br /> Page 2 of 2 <br /> Prior to commencement of well destruction activities each well casing was sounded with a Solinst <br /> 4 water level meter to ensure that no obstructions were present in the 'casings. <br /> Wells MW-2 through MW-12 were drilled-out to their total depth using a CME-75 HT hollow stem <br /> auger drill rig equipped with 8-inch diameter hollow stem augers. All original well construction <br /> materials were removed(including well casing, screen, filter pack, and annular seal)to ensure that <br /> no residual contamination was sealed within the abandoned borehole. The remaining borehole was <br /> + then backfilled to surface grade with a grout mixture(A ratio of six gallons water for every 94-pound <br /> sack of pordand cement will be utilized in preparation of the grout mixture). <br /> Wells MW-1 and MW-13 were fitted with a pressure tight adapter connected to a hose extending <br /> from the grout mixer. The grout mixture was pumped into each well°casing for five minutes under <br /> approximately 5-10 pounds per square inch(psi)of pressure.The well boxes were then removed and <br /> a the wells were over-drilled to three feet bsg using a CME k75 HT hollow stem auger drill rig <br /> equipped with 8-inch diameter hollow stem augers. The top three feet of the well casings were then <br /> I. removed and the borings were grouted to the near surface using the p'ortland cement grout mixture. <br /> The above referenced well construction materials and soil cuttings were hauled off-site for disposal <br /> at Chemical Waste Management,Kettleman City, CA.; a copy iof the non-hazardous waste manifest <br /> is included in Appendix B.
