LABORATORY RESULTS <br /> A total of four groundwater samples collected from monitoring wells MW-1 through MW-4 were <br /> submitted for the following analysis during the First Quarter 2005 sampling event <br /> • Benzene, Toluene, Ethylbenzene, Total Xylenes by EPA Method 8260 (BTEX), <br /> • Total Extractable Petroleum Hydrocarbons as referenced to Diesel (TPH-D) by EPA <br /> Method 8015B, and <br /> • Total Purgeable Petroleum Hydrocarbons as referenced to Gasoline (TPH-G) by EPA <br /> Method 8015B <br /> For a summary of these findings, and previous groundwater sampling results, refer to Table 2 <br /> included In the Appendix of this report In summary, TPH-D was detected from the groundwater <br /> sample collected from MW-1 at a concentration of 14 mg/l The laboratory noted that the TPH- <br /> D concentration also included lighter-end hydrocarbons TPH-G was also detected in this <br /> groundwater sample at 1 5 mg/l Ethylbenzene and total xylene were detected in groundwater <br /> collected from MW-1 at 1 4 µg/l and 0 57 µg/l Benzene and Toluene were not detected in the <br /> groundwater sample collected from MW-1 None of the requested petroleum analytes were <br /> detected in groundwater samples collected from perimeter monitoring wells MW-2, MW-3 or <br /> MW-4 The laboratory analytical data sheets and chain of custody forms are included in <br /> Appendix C <br /> 28209 T061ST05 8717/LTV lv Page 8 of 1 I <br /> ©2005, Kleinfelder, Inc lune 23,2005 <br />
