Fremont St., Stockton <br /> WORKPLAN FOR PLACING SOIL/WATER PROBES: <br /> 1. Mobilize properly licensed push-type equipment at approximate locations shown on <br /> PLATE A. Actual locations will depend upon locations of underground utilities and <br /> pipelines, and buildings. <br /> 2. Soil samples in each probe hole will be taken at 4', 8', and 12' below grade as directed by <br /> the geologist in charge. The samples will be described, sealed, and preserved for <br /> analysis by a State Certified laboratory using prescribed WJH field procedures. <br /> 3. Water samples will be taken in each hole by use of a hydropunch or similar tool. They <br /> will be preserved and stored under prescribed WJH field protocol. <br /> 4. Samples will be analysed for benzene, ethylbenzene, toluene, xylene & TPH as gasoline <br /> using Tri-Regional & San Joaquin Co. detection limits. Oxygenates have riot been <br /> analyzed from soil samples taken during earlier work, but none have detected in water <br /> samples. We do not believe that it is necessary to perform that analysis. <br /> • 5. All probe holes will be thoroughly grouted from bottom to the surface as directed by the <br /> San Joaquin Co. EHD. <br /> Additional work { soil borings and/or monitoring wells,) will be discussed after completion <br /> of this phase. <br /> When approval has been received, we will solicit bids from qualified vendors and prepare a <br /> pre-approval package for our client to submit to the Cleanup Fund. When that approval is <br /> received, we will submit a drilling permit application, and schedule the work. <br /> Wm. J.
