Historic UST Investigation Report 630 N.California Street June 1,2011 Page 3 quantified as motor oil (TEPH-MO) and diesel (TEPH-D) by EPA Method 8015M. Three soil samples were also analyzed for CAM 5 metals (cadmium, chromium, lead, nickel, and zinc) by EPA Method 601 OB. LABORATORY ANALYTICAL RESULT Laboratory reports and chain of custody sheets are included in Attachment C. Laboratory analytical results are summarized below, on the follow.ng pages, and in Figure 3, Attachment A. None of the fuel oxygenates listed on the previous page and no TEPH-MO or TEPH-D were detected at or above the laboratory reporting limits. Benzene was also not detected at or above the laboratory reporting limits. Toluene, ethylbenzene, total xylenes, and T H-G were detected in several soil samples as indicated in Table 1, below. No constituents were detected at or above the laboratory reporting limits in boring GP3. Sample depths (bottom of sampled interval) correspond to the last digits on the sample identifier and are in feet bgs.
