(GTI) is presenting this letter in <br /> response to your request for clarification of several points <br /> noted during your review of the assessment report for the above <br /> referenced site. The report is entitled "Assessment Report, Sub-- . <br /> surface Hydrocarbon Investigation, the Beverage Source,. Inc . , ISC <br /> Winery, 1 West Turner Road, Lodi. , California" and is dated' May <br /> 25, 1988 . In the following paragraphs, GTI will address all the <br /> points noted in your letter to Mr. Scott Stoner of The Beverage <br /> Source, dated August 2 , 1988. <br /> A question was raised -regarding the<, field screening procedures <br /> used during the drillifig operations at the site. GTI used a ' <br /> Photovac TIP photo-ionization detector (PID) utilizing a 10. 2 <br /> electron volt ionization source to field screen all soil samples. <br /> GTI neglected to include the results of the field screening <br /> process within the assessment report . This oversight may be <br /> explained by the fact that all soil samples yielded non-de- <br /> tectable readings. Revised drill logs have been enclosed with <br /> this letter which include the PID readings (Attachment ' 2) . <br /> A question was raised regarding diesel odor noted in MW-1 . The <br /> odor was not noted in Sample F as stated in your. , letter, but in <br /> the cuttings between Samples F and G. Subsequently, Sample G was <br /> submitted. for laboratory analysis and was found to yield non- <br /> Offices throughout the U.S..Canada and Overseas <br />
