Total hydrocarbon and total lead <br /> analyses were also performed. The analytical results of the soil and water <br /> { s samples are presented in the Appendix. <br /> r VI. DISCUSSION <br /> E Gasoline and related constituents were detected in the soil and water samples <br /> taken beneath the site of the removed fuel storage tanks. In addition, the soil <br /> r.: <br /> observed by our geologist in the field possessed a noticeable gasoline odor and a =- <br /> recordable amount of volatile hydrocarbons using the PID. Further investigations would <br /> be necessary in order to assess the extent of the chemicals in the local soil and <br /> ground water. <br /> Vill, LIMITATIONS <br /> This report was prepared in accordance with the generally accepted standard of <br /> practice which exists in Northern California at the time the report was written. It <br /> should be recognized that definition and evaluation of geologic conditions is a difficult <br /> and inexact art. Judgements leading to conclusions and recommendations are generally <br /> made with an incomplete knowledge of the subsurface _onditions present. More <br /> extensive studies, including additional subsurface investigations can tend to reduce the <br /> inherent uncertainties associated with subsurface modeling. If the client wishes to <br /> reduce the uncertainty beyond the level associated with this study, Kleinfelder & <br /> Associates should be notified for additional consultation. <br /> Tw_ <br /> r, <br />
