Soil samples collected by Geomatrix Consultants, Inc., and analyzed by Sevem Trent Laboratories (STL San Francisco), Inc. , of Pleasanton , California, <br /> for total petroleum hydrocarbons (TPH) using EPA Method 8015M and polynuclear aromatic hydrocarbons (PAH) using EPA Method 8270 SIM, <br /> I 2. fl bgs = feet below ground surface <br /> 3. B(a)P TEFs = Benz(a)pyrene Toxic Equivalency Factors are used to assess the relative toxicity of PAHs and PAH derivatives as a group (OEHHA , 1993). <br /> If a PAH was not detected, one-half the detection limit was multiplied by the corresponding potency equivalency factor (PEF). <br /> B(a)P TEFs were only calculated if one or more of the carcinogenic PAHs were detected . The PEFs used to calculate <br /> B(a)P TEFs were 1 .0 for benzo(a)pyrene ; 0. 1 for benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, and <br /> indeno( 1 ,2,3-cd)pyrene; 0.01 for chrysene; and 0. 35 for dibenz(a,h)anthracene. <br /> I 4. < = Analyte was not detected at or above the laboratory reporting limit indicated. <br /> 5 . NA = Not Analyzed <br /> I 6. ND = Not detected <br /> 7. Bolded values indicate that the analyte was detected at the concentration indicated . <br /> 8. J = target analyte was positively identified ; the associated numerical value is the approximate concentration of analyte in the sample <br /> Results flagged due to low percent recoveries in the matrix spike/matrix spike duplicate results for the sample batch with elevated TPH detections. <br /> I:\Doc_Safe\7000s\7066.001\Reporls\2005 Soil lnvesligalion and Well Survey\2 Tables\Snmmary Tables Gravel Pits-Tables 1 -7 Page I of I <br />
