Historic UST Investigation Report <br /> 630 N. California Street <br /> June 1 , 2011 <br /> Page 3 <br /> quantified as motor oil (TEPH-MO) and diesel (TEPH-D) by EPA Method 8015M. Three soil samples <br /> were also analyzed for CAM 5 metals (cadmium, chromium, lead, nickel, and zinc) by EPA Method <br /> 6010B . <br /> LABORATORY ANALYTICAL RESULTS <br /> Laboratory reports and chain of custody sheets are included in Attachment C. Laboratory analytical <br /> results are summarized below, on the following pages, and in Figure 3, Attachment A. None of the fuel <br /> oxygenates listed on the previous page and no TEPH-MO or TEPH-D were detected at or above the <br /> laboratory reporting limits. Benzene was also not detected at or above the laboratory reporting limits. <br /> Toluene, ethylbenzene, total xylenes, and TPH-G were detected in several soil samples as indicated in <br /> Table 1 , below. No constituents were detected at or above the laboratory reporting limits in boring GP3 . <br /> Sample depths (bottom of sampled interval) correspond to the last digits on the sample identifier and are <br /> in feet bgs. <br /> Table 1 - Laboratory Analytical Results - Detected VOCs and Petroleum Hydrocarbons <br /> Constituent <br /> Units : mg/kg <br /> Sample ID Date <br /> p Sampled - - TEPH- - TEPH- <br /> B --Tj E X TPH-G MO D <br /> Detection Limits* 0.005 0.005 0.005 0.010 1 .0 20 5 .0 <br /> GPl -12 5/5/2011 <0.005 <0.005 <0.005 <0.010 < 1 .0 <60 <15 <br /> GPI -16 5/5/2011 <2.0 909 73 330 41100 <20 <5.0 <br /> GPl -24 5/5/2011 <0. 50 6°1 13 59 690 <60 <15 <br /> GPl -30 5/5/2011 <0.005 <0.005 <0.005 0.023 <1 .0 <20 <5 .0 <br /> GP2-15 5/5/2011 <4.0 15 190 780 87100 <60 <15 <br /> GP2- 18 5/5/2011 <2.0 48 88 370 3,900 <60 <15 <br /> GP2-24 5/5/2011 <2 .0 33 51 230 2,800 <60 <15 <br /> GP2-30 5/5/2011 P<O005 <br /> <0.20 0.25 1 .3 200 <60 <15 <br /> GP3-11 5/5/2011 <0.005 <0.005 <0.010 <1 .0 <20 <5 .0 <br /> GP3-24 5/5/2011 <0.005 <0.005 <0.010 <1.0 <20 <5 .0 <br /> GP3-27 5/5/2011 <0.005 <0.005 <0. 010 <1 .0 <20 <5 .0 <br /> GP3-30 5/5/2011 <0.005 <0.005 <0 010 <1 .0 <20 <5 .0 , <br /> GP4-12 5/5/2011 <0.005 <0.005 0.025 < .0 <20 <5 .0 <br /> GP4-21 5/5/2011 <0.005 <0.005 <0.010 <1 .0 <20 <5 .0 <br /> GP4-305/5/2011 <0.4 <0A 5°2 26 480 <60 <15 <br /> Units: mg/kg = milligrams per kilogram = parts per million. <br /> *At dilution factor = 1 <br /> Bolded values indicate detected constituents. <br /> B, T, E = benzene, toluene, ethyl benzene.
