Bold values indicate constituent was <br /> L detected at or above the laboratory reporting limit. BTEX compounds were not detected at or above the <br /> laboratory reporting limit of 0.005 mg/kg for the two subsurface samples (RS 1-1 and RS 4-3). TPH-G <br /> was detected at 3.2 mg/kg for one subsurface sample at three feet bgs (RS 4-3). The laboratory notes for <br /> ►; the analysis were "strongly aged gasoline or diesel range compounds are significant with no recognizable <br /> pattern". TPH-G was not detected at or above laboratory reporting limits of 1.0 mg/kg for the remaining <br /> surface and subsurface soil samples.TPH-D was detected in surface soil samples RS 1-0,2-0, 3-0, and 4- <br /> L, 0 at 11, 11,29, and 8.2 mg/kg,respectively. The laboratory described the results of these analyses as, `oil <br /> range compounds are significant and diesel range compounds are significant". TPH-D was detected in <br /> subsurface samples RS 1-1, 2-1, 3-1.5, and 4-3 at 100, 16, 150, and 26 mg/kg, respectively. The <br /> Llaboratory noted the following: `oil range compounds are significant" for RS 2-1; and `oil range <br /> compounds are significant; diesel range compounds are significant-no recognizable pattern' for the <br /> remaining sample analyses. TPH-MO was detected in surface soil samples RS 1-0, 2-0, 3-0, and 4-0 at <br /> 180, 110, 150, and 64 mg/kg, respectively. TPH-MO was detected in subsurface samples RS 1-1, 2-1, 3- <br /> L1.5, and 4-3 at 370, 150,470, and 37 mg/kg,respectively. <br /> L <br /> L <br /> Lw CONDOS <br /> i� <br />
