ANALYTICAL RESULTS OF SOIL SAMPLES <br /> TPH-g was detected in soil sample MW-4-20' at concentrations as high as 160 milligrams per <br /> kilogram(mg/kg). <br /> TPH-mo was detected in soil samples MW-4-20',MW71-25',and MW-5-20'at concentrations of4.7 <br /> mg/kg, 5.7 mg/kg, and 7.5 mg/kg, respectively. <br /> MTBE and BTEX compounds were not detected above laboratory reporting limits in any of the soil <br /> ' samples collected and analyzed. <br /> Analytical results of soil samples are summarized on Table 2.The laboratory report(laboratory order <br />,.' # A99121401) and chain-of-custody forms are included in Appendix C. <br /> ' 4.4. ANALYTICAL RESULTS OF WATER SAMPLES <br /> TPH-g was detected in water samples from MW-1, MW-2, MW-3, MW-4, and MW-5 at <br /> lie concentrations of 3,500 micrograms per liter (ug/1), 5,100 ug/l, 3,300 ug/1, 3,600 ug/l, and 31,000 <br /> ug/l, respectively. <br /> ' TPH-mo was not detected above laboratory reporting limits in any of the ground water samples <br /> collected and analyzed. <br /> ' BTEX compounds, ethylbenzene and xylenes were detected in samples from MW-5 at <br /> concentrations as high as 2,400 ug/1 and 2,500 ug/l, respectively. <br /> ' Fuel oxygenate tert-butanol was detected by EPA Method 8260B in the ground water samples <br /> collected from MW-2,MW-3,MW-4 and MW-5 at concentrations of 42 ug/l, 130 ug/l,28 ug/l, and <br /> ' 98 ug/l, respectively. <br /> 1,2-DCA was detected in the ground water sample from MW-5 at a concentration of 0.68 ug/l. <br /> Analytical results of ground water samples are summarized on Table 3.
