3.0 Site Investigation Results <br /> 3.1 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,just south of the CPT location 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 <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 A <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 ID Sample Sample Temperature pH Conductivity <br />' Depth(ft) Depth(m) (2C) (PS/cm) <br /> SC-1-65' 65 198 209 705 1191 <br /> SC-1-90' 90 274 168 756 8186 <br /> 1 SC-1-100' 100 305 188 743 1 6681 <br /> Groundwater samples were collected from the each of the targeted water bearing zones Total <br /> Petroleum Hydrocarbons as gas (TPHg) was detected in the groundwater samples collected from <br /> SC-1-65' and SC-1-100' at concentrations of 130 and 84 micrograms per liter (ug/l), <br /> respectively Benzene was detected in all groundwater samples at concentrations ranging <br /> between 1 0 and 7 7 Pg/I Toluene was detected in SC-1-90' and SC-1-100' at concentrations of <br /> I I and 2 2 pg/l, respectively Ethylbenzene was detected in all groundwater samples at <br /> concentrations ranging between 14 and 5 2 µg/1 Total Xylenes were detected in all <br /> groundwater samples at concentrations ranging between 7 6 and 28 6 µg/1 Groundwater <br /> samples were not reported to contain concentrations of Total Petroleum Hydrocarbons as diesel <br /> (TPHd), Ethyl-t-butyl ether(ETBE), Di-isopropyl ether (DIPE), Methyl tertiary butyl ether <br /> aemz <br /> r�,„ar�y i�snca�pncoMMorrvw ,a +s3szr�z�ao� 3-1 <br />
