I <br /> Mr Donald Kirk Page 4 <br />' September 22, 1997 <br /> • ground water samples were analyzed for TPH, including motor oil, using EPA <br />' Method 8015-full range, and for VOCs using EPA Method 8260 <br /> Boring Destruction <br />' Following completion of the borings and collection of soil and ground water <br /> samples, Gregg Drilling grouted all soil borings to the surface The grout slurry <br />' consisted of bentonite or neat cement nruxed with approximately 8 gallons water <br /> per sack A tremae pipe was not used because less than five feet of standing <br /> water was measured an the boreholes Boreholes were completely filled with <br /> grout seal and capped with cement to grade Mr Harlin Knoll, a County <br /> inspector, witnessed and approved the grouting of one of the borings (FS3) <br />' All aspects of the Phase Il investigation were performed under the direction of a <br /> California Registered Geologist (RG) Geoprobe and HydroPunch sampling <br />' were performed by Gregg Drilling and Testing of Martinez, California, a <br /> California-licensed C-57 drilling contractor Chemical analysis of soil and <br /> ground water samples were performed by Quanterra Environmental Services, a <br />' California-certified analytical laboratory <br /> The results of the Phase II investigation are presented below <br /> FINDINGS <br />' ERM's findings associated with the Phase II investigation, which included <br /> collection of shallow soil and ground water grab samples near two former UST <br />' locations and around the Forklift Shop, are summarized below Site figures and <br /> data tables are presented an Attachment A <br />' Soil Sampling <br />' UST Borings <br /> ERM collected soil samples from two Geoprobe boreholes at each of the two <br /> presumed former UST locations The UST1 location (Figure 2, Attachment A) as <br /> between a loading ramp on the west end of the production building and the crate <br /> loading dock,which as attached to the south end of the tank farm An apparent <br />' UST fall pipe beneath a manhole cover was observed during the geophysical <br /> survey The size and orientation of the tank could not be determined due to <br /> interference with magnetometer readings, presumably caused by nearby metal <br /> objects and reinforced concrete Boring UST1N (labeled USTI on chain of <br /> . custody forms and lab data sheets) was drilled approximately 15 feet north of the <br />
