3. Terrestrial Technology, Inc. will be on site when the field work <br /> is proceeding. A Staff Geologist will oversee the taking of soil <br /> samples and the establishment of soil profiles of each boring <br /> as they are made. Standard soil identification methods and <br /> nomenclature will be used. Soil profiles will be shown on T.T. I . <br /> soil profiles forms. <br /> 4. Soil samples will be taken from each boring and field screened <br /> by inspection for as to which samples will be analyzed by a <br /> laboratory. <br /> 5. Those samples chosen to be analyzed by a California certified <br /> laboratory for total petroleum hydrocarbon (TPH) , including benzene, <br /> xylene and ethylbenzene (BTX) , will be analyzed using the following <br /> methods: <br /> Contsituent Method <br /> A. T.P.H. GCFID (5030) <br /> B. B.T.X. GCFID (602) <br /> Due to our past work near this site, we feel these extractable <br /> test methods are satisfactory. Samples taken in the saturated <br /> zone will also be tested by the above methods. No water samples <br /> will be taken at this stage. <br /> 6. The soil boring contractor will obtain a permit from the San Joaquin <br /> Local Health District and notify said district when borings are <br /> to be made and when filling of borings with bentonite/concrete <br /> slurry is to occur. Fourty eight (48) hour notice will be given <br /> (minimum). <br /> 7. A report will be prepared by T.T. I . for SEECON Construction Company <br /> who will provide for distribution as appropriate. L.A. Moldenhauer, <br /> a California Registered Civil Engineer, will affix his R.C.E. <br /> stamp and signature to this report. The report will include <br /> 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, <br /> soil identification, and findings , water table elevations , <br /> soil analysis (laboratory) and other pertinent observations. <br /> A general statement as to the overall geologic and soil <br /> conditions at the site will be given. <br /> D. General comments that can be made based on the information <br /> available from the 5 soil borings. <br />
