The purpose of this <br /> investigation was to assess the likelihood that soils beneath the site have been <br /> adversely impacted by the former presence of hydrocarbons contained within <br /> Underground Storage Tanks (USTs) <br /> Soil samples collected at the time of this investigation were analyzed for petroleum <br /> hydrocarbons and Volatile Organic Compounds (VOCs). The laboratory reported that <br /> soil samples from one of the borings has high concentrations of Total Petroleum <br /> Hydrocarbons in the form of gasoline (TPHg) and its VOC constituents Benzene, <br /> Toluene, Ethyl benzene, and Xylenes (BTEX). Based on the laboratory report for the <br /> samples collected for analysis from the site, field observations and our professional <br /> judgement, it appears that the soils at the site have been adversely impacted by <br /> TPHg and BTEX which has been released from the former USTs. <br /> Should you have any questions or require supplemental information, please do not <br /> hesitate to contact us. <br /> I _ <br /> Sincerely, <br /> Fes_ <br /> Udc- i <br /> { �r <br /> I _ � J � N° 0QJ56 <br /> Robb Welch iendall W. rice, EAS �ir <br /> Staff Geologist President <br /> OF C <br /> 1220 Crossman Avenuu Suite 21717•Sunnyvale Califumiri 94059•(4178]7471414 •FAX(408]745-1009 <br /> I <br />
