ter <br /> amec <br /> TABLE A-2 <br /> SUMMARY OF SVOC AND PAH SOIL SAMPLE ANALYTICAL RESULTS <br /> TRACY RAIL YARD = AOI =4 AND AOI -5 <br /> Tracy Rail Yard Off Site East Area <br /> Tracy , California <br /> Notes <br /> 1 . Analytical results for the 2005 and 2006 samples were compiled from tables presented in previous consultants ' reports . AMEC Geomatrix, Inc. did not independently review laboratory data sheets . Samples collected by AMEC Geomatrix, Inc. in 2009 and <br /> 2010 were analyzed by Lancaster Laboratories , Inc. , of Lancaster, Pennsylvania , for PAHs using U . S . EPA Method 8270 with selective ion monitoring (SIM) . Detected anylytes are shown in bold face-type . <br /> 2 . BaP TEQs were calculated for each sample that had at least one carcinogenic PAH detection above the laboratory reporting limit. All results for non-detected carcinogenic PAHs were set at half of the detection limit. The equivalent is calculated using <br /> toxicity equivalency factors , adjusting the toxicity of the carcinogenic PAHs to the TEQ of benzo (a ) pyrene . <br /> Abbreviations <br /> -- = not analyzed <br /> < = analyte was not detected at or above the laboratory reporting limit indicated <br /> AOI = area of interest <br /> BaP TEQ = benzo (a ) pyrene toxicity equivalent <br /> bgs = below ground surface <br /> J = target analyte was positively identified ; the associated numerical value is the approximate concentration of analyte in the sample <br /> NDC = no carcinogenic PAHs were detected , therefore a BaP TEQ was not calculated <br /> ND = not detected , reporting limits vary <br /> PAHs = polynuclear aromatic hydrocarbons <br /> SVOCs = semi -volatile organic compounds <br /> AMEC Geomatrix , Inc . <br /> X:\16000s\161130\4000\OffSiteEastWP_061511 \3 App A\Tbl A-2_Soi1_SV0Cs_PAHs.x1s Page 2 of 2 <br />
