E <br /> LEVINE•FRICKE <br /> The boring samples were submitted to Quanteq Laboratories of <br /> Pleasant Hill, California, a state-certified laboratory, for <br /> analysis by EPA Method 8240 for acetone. The surface soil <br /> samples were submitted to Asbestos TEM Laboratory of Berkeley, <br /> California, for Polarized Light Microscopy (PLM) analysis. <br /> Acetone was not identified above method detection limits in <br /> the soil boring samples. Asbestos fibers were not identified <br /> above method detection limits in the two surface soil samples. <br /> Laboratory reports and chain-of-custody forms are included in <br /> Attachment 2. <br /> UST REMOVAL AND PREVIOUS SOIL INVESTIGATION <br /> An 8, 000-gallon-capacity UST used to store waste acetone was <br /> removed by a contractor on December 20, 1989 (Figure 2) . The <br /> bottom of the UST excavation was at approximately 13 feet bgs. <br /> The UST removal was monitored by an inspector from the SJCEHD. <br /> One soil sample was reportedly collected by a previous <br /> consultant from each of four borings, drilled to approximately <br /> 15 feet bgs after the UST excavation was backfilled. Two of <br /> the borings were drilled outside the UST excavation (SB-3 and <br /> SB-4) and two were drilled in the backfilled excavation (SB-1 <br /> and SB-2) . The borings were drilled using a hollow-stem <br /> auger. Samples were collected in 2x6-inch brass tubes using a <br /> split-spoon sampler. <br /> The four soil samples (SB-1. 15, SB-2 . 16, SB-3. 15, and SB-4. 16) <br /> were submitted to Superior Analytical Laboratory, Inc. , of San <br /> Francisco, California, for analysis by EPA Method SW-816 <br /> Method 8240 for volatile organic compounds (VOCs) , including <br /> acetone. No VOCs were reported above detection limits in any <br /> of the four samples.
