laboratory results indicate no contamination exists. If it is found <br /> that contamination does exist', an approved waste hauler will be used <br /> to move this soil to an approved disposal site. <br /> 3. Terrestrial Technology, Inc. will be on site when the field work is <br /> proceeding. A licensed California Civil Engineer will oversee the taking <br /> of continuous soil cores and the establishment of soil profiles of each <br /> boring as they are made. Standard soil identification methods and <br /> nomenclature will be used. Soil profiles will, be shown on T.T. I. soil <br /> profile forms. <br /> 4. Soil samples will be taken from each boring and field screened by <br /> in3 pection for asto which samples will be analyzed by a laboratory. <br /> F ( 04ffrrale-t wr rz ?frO.a . -_ ,bA <br /> 5. Those samples chosen to be analyzed by a California certified laboratory <br /> for total petroleum hydrocarbon (TPH) , including benzene, toleune, xylene <br /> and ethylbenzene (BTX), will be analyzed using the following methods: <br /> Constituent Method <br /> A. T.P.H. ) <br /> B. B.T.X. <br /> Due to our past work on this site, we feel these extractable test methods <br /> are satisfactory. Samples taken in the saturated zone will also be tested <br /> by the above methods. No water samples will be taken at this stage. <br /> 6. The soil boring contractor will obtain a drilling permit from the San <br /> Joaquin Local Health District and notify said district when borings are <br /> to be made and when filling of boring's with bentonite/concrete slurry <br /> is to occur. Twenty four (24) hour notice will be given (minimum) . <br /> 7. A report will be prepared by T.T. I . fol <br /> rAdleson, Hess, Christianson and <br /> Kelly who will provide for distribution as appropriate. L. A. <br /> Moldenhauer, a California Registered Civil Engineer, will affix his R.C.E. <br /> stamp and signature to this report. The eport will include the following: <br /> A. Introduction and work description <br /> B. Summary of the work and analysis of soil samples <br /> C. Location of work (map) and description of soil profiles, soil <br /> identification, and findings, water table elevations, soil analysis <br /> (laboratory) and other pertinent observations. A general statement <br /> as to the overall geologic and soil conditions at the site will be <br /> given. <br /> D. General comments that can be made based on the information available <br /> from the 8 soil borings and possible I3 to 4 backhoe pits. <br /> Page 2 of 3 <br />
