8 <br /> 3.0 Site Investigation Results <br /> 3.9 Underground Utility Survey <br /> The geophysical underground utility survey revealed subsurface utilities to the south and east of <br /> the CPT locations It appeared from both geophysical survey results as well as asphalt patching <br /> that there were electric lines that ran east,lust south of the CPT Iocation and made a turn to the <br /> north These were considered to be too close to the CPT location and it was recommended that <br /> the CPT location be moved at least 2 feet to the northwest Appendix D contains the GPR field <br /> records <br /> 3.2 Cone Penetrometer Testing <br /> The CPT log indicated that potential water bearing zones were located at 19 8 meters (65 feet), <br /> 27 4 meters (90 feet), and 30 5 meters (100 feet) The cone penetration test data is included in <br /> Appendix B <br /> 3.3 Groundwater Conditions <br /> Temperature, pH, and conductivity of each groundwater sample were recorded on field report <br /> forms These measurements are presented below <br /> Sample Sample Sample Temperature Conductivity <br /> ID Depth(ft) Depth(m) ('C) pH (NS/cm) <br /> SC-1-65' 65 198 209 705 1191 <br /> SC-1-90' 90 274 168 756 8186 <br /> SC-1-100' 100 305 188 743 6681 <br /> Groundwater samples were collected from the each of the targeted water bearing zones TPHg <br /> was detected in the groundwater samples collected from SC-1-65' and SC-1-100' at <br /> concentrations of 130 and 84 micrograms per liter (µg/l), respectively Benzene was detected in <br /> all groundwater samples at concentrations ranging between 10 and 7 7 µg11 Toluene was <br /> detected in SC-1-90' and SC-1-100' at concentrations of 1 1 and 2 2 µg/l, respectively <br /> Ethylbenzene was detected in all groundwater samples at concentrations ranging between 14 <br /> and 5 2 pg/1 Total Xylenes were detected in all groundwater samples at concentrations ranging <br /> between 7 6 and 28 6 µg/1 Groundwater samples were not reported to contain concentrations of <br /> Total Petroleum Hydrocarbons as diesel (TPHd), Ethyl-t-butyl ether(ETBE), Di-isopropyl ether <br /> Mtseeoo2wrs+s��aa�n�an ex 3-1 <br /> 87UJ2 <br />
