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 2010 were analyzed by Lancaster <br /> 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 toxicity equivalency factors, adjusting the toxicity of the carcinogenic PAH: <br /> 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 /> BaP TEQ = benzo(a) pyrene toxicity equivalent <br /> bgs = feet below ground surface <br /> J = target analyte was positively identified ; the associated numerical value is the approximate concentration of analyte in the sample <br /> ND = not detected; reporting limits vary <br /> PAHs = polycyclic aromatic hydrocarbons <br /> SVOCs = semi-volatile organic compounds <br /> AMEC Geomatrix, Inc. <br /> XA16000s\161140\4000 REGULATORY\South_WP_071211\4 Apnd A\Tbl A-1 S0_TPHBTEX_PAHs.xlsx Page 2 of 2 <br />
