These borings will exte:td <br /> to 115 feet below grade. Prior work at the site indicated a Clay i <br /> la Yer at approximately 115 feet. Prior work at the site also <br /> imately 115 feet had non-detectable <br /> indicated the units at approx <br /> Levels of hydrocarbon cantaminataon. <br /> As you can tell from this figure, these borings [which will be <br /> I <br /> constructed into wells] are inthe City of Stockton Stockton toY <br /> A special license will be required from the City <br /> oto the Right-of-way. <br /> place the wells <br /> a C-57 licensed driller and e-inch diameter hollow <br /> JPCA will use - <br /> stem augers. Soil samples will be collected at each 5 ft level <br /> interval or at significant changes in l.ithology commencing at a <br /> 1 depth of ten feet, using a split spoon tube sampler loaded with <br /> pre-cleaned brass tubes. <br /> will <br /> be field checked with. a Photoioni.zation <br /> soil samples es <br /> All p organic vapors. All soil samples <br /> Detector [PID) which measures q <br /> in excess of background levels will be analyzed. <br /> The cuttings will be stored on visqueen and covered with <br /> visqueen. <br /> Soil samples collected in the lowest brass liner will be <br /> preserved by covering both ends with Teflon tape and capping with <br /> plastic .caps. soil samples will be labeled and logged under <br /> Chain-of- Custody (COC) control . soil samples will be stored in <br /> a cooler with ice, transported to a state certified laboratory <br /> for analysis with COC documentation. <br /> The borings will be logged by inspection of the samples and <br /> classified Luing the .Unified Soil Classification System by a <br /> California Certified Engineering Geologist . <br /> A maximum of B4 soil samples is anticipated to be collected in <br /> this task. <br /> Each boring will be pressure grouted to a depth of approximately <br /> ! 75 feet . Then a 2 inch diameter monitoring well. will be placed <br /> 4 <br />
