Weber Ave., Third Floor <br /> Stockton, CA 95201-0388 <br /> Subject: Quarterly Monitoring Report—Del Monte Disco Site <br /> Dear Mr. Rowe: <br /> Enclosed is the Quarterly Monitoring Well results for the sampling that occurred on August 12, <br /> 1997. You will note that I have not had the data tabulated with the past data by CH2M Hill as I <br /> do not think there was a reason to do so this quarter. However, I will have this data entered at <br /> the same time as the results of the next sampling event so all the data will be together. <br /> These results differ from previous results in that groundwater has dropped slightly since the last <br /> sampling event and SVE-south shows high concentrations ofBTEX. SVE-south is not a <br /> monitoring well we have sampled regularly in the past but we will include it again in our next <br /> sampling. Lastly, all monitoring wells tested ND for the four ether oxygenates. <br /> If you have any questions, you can reach me at 510-944-7276. <br /> Sincerely, <br /> I <br /> Richard Fish <br /> Environmental Manager, Western Region <br /> cc: Nancy Bice - Geomatrix <br /> Bern Baumgartner - CH2M Hill <br /> Grant Stewart - CH2M Hill <br /> Steve Balling - Del Monte <br /> i <br /> i <br /> I <br /> I ( <br />
