1 <br /> TABLE 4 continued <br /> RESULTS OF TPH AND PAH ANALYSES <br /> BASELINE AND CONFIRMATION SAMPLES <br /> a See Figure 2 for approximate sample locations. <br /> b Total petroleum hydrocarbons(TPH)as diesel analyzed by EPA Method 8015 Modified. <br /> ' c Samples were submitted to a silica gel cleanup using EPA Method 3630 as modified by Friedman&Bruya, Inc., prior to TPH analysis. <br /> d Waste Extraction Text(WET)performed prior to analysis,using deionized water as the extractant. <br /> e WET polynuclear aromatic hydrocarbons(PAH)analyzed by EPA Method 8310. These results reflect the sum of PAH constituents. <br /> f Raised reporting limit due to high analyte levels. <br /> g Surrogate not detected because of required sample dilution. <br /> ' h Surrogate recovery outside of limits due to sample matrix interference. <br /> i Surrogate recovery is outside of control limits. <br /> J Raised reporting limit due to matrix interference. <br /> k Average concentntions are calculated assuming non-detect occurrences are equal to one-half the repotting limit. <br /> mg/kg Milligrams per kilogram <br /> ng1L Micrograms per liter <br /> NA Not analyzed <br /> ' IYD Not detected <br /> Dup Duplicate sample <br /> c Results were below reporting limit noted, <br /> INote: Shaded rows designate baseline samples. <br /> tracytM3,tb4/01-30-971ulcwil]iltracylreport5lrptUG3 <br /> TerraNext <br /> i <br />
