ANALYTICAL RESULTS OF SOIL SAMPLES <br /> ' A total of twelve soil samples were submitted to a DHS-certified laboratory for analysis of TPH-g, <br /> TPH-d, BTEX, MTBE and fuel oxygenates. Laboratory analysis of twelve soil samples did not <br /> ' detect any total petroleum hydrocarbons, volatile aromatics or fuel oxygenated compounds in any <br /> of the analyzed soil samples. The analytical results of selected soil samples are summarized in Table <br /> 1. The laboratory reports (Castle Analytical Laboratory Reference No. 2188 and McCarnpbell <br /> Analytical Inc. Lab I.D. No. 09144 through 09155) and chain-of-custody forms are included in <br /> Appendix D. <br /> 3.5. ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br /> ' Four ground water monitoring well samples were submitted to a DHS-certified laboratory in April <br /> 1999. Utilizing EPA Method 8015M, TPH-g was not detected in ground water samples collected <br /> lie from wells MW-1 through MW-4; TPH-d was detected in a ground water sample collected from <br /> MW-1 at a concentration of 130 micrograms per liter(yg/1). <br /> ' Utilizing EPA Method 8020,BTEX compounds were not detected in ground water samples collected <br /> from wells MW-1 through MW-4; however, MTBE was detected in ground water samples collected <br /> from wells MW-2 and MW-3 at concentrations of 2.5 ,ug/1 and 0.71 jig/I, respectively.. <br /> Utilizing EPA Method 8260, MTBE was detected in a ground water sample collected from MW-2 <br /> ' at a concentration of 1.9 µg/l; No other fuel-oxygenate analytes were detected above laboratory <br /> reporting limits. <br /> The analytical results of quarterly ground water samples are summarized in Table 3. The Iaboratory <br /> reports (Castle Analytical Laboratory Reference No. 2188 and McCampbell Analytical Inc. Lab I.D. <br /> No. 09156 through 09159) and chain-of-custody forms are included in Appendix E. <br /> ' 4.0. SUMMARY AND CONCLUSIONS <br /> Based on the results of soil sampling, ground water monitoring and ground water sampling activities <br /> performed in April 1999, AGE concludes: <br /> First encountered ground water is approximately 15 feet bsg; first observed saturated soil <br /> ' Advanced GeoEnvironmental,Inc. <br /> 1 <br />
