(Aegis), requested the monitoring and sampling interval <br /> be reduced to annually. The San Joaquin County Public Health Services, Environmental <br /> Health Division (SJCPHS/EHD) responded in a letter dated June 30, 1993, stating the site <br /> should be sampled in October 1993. After reviewing the results, the SJCPHS/EHD would <br /> then consider reducing the monitoring and sampling interval to annually. The results <br /> were submitted to your office in a report dated January 12, 1994. <br /> Petroleum hydrocarbons have not been indicated in laboratory analyses of groundwater <br /> samples collected in 10 of the 13 groundwater monitoring and sampling events conducted <br /> at this site. Historical groundwater analytical results have indicated infrequent, randomly <br /> distributed, low concentrations of total petroleum hydrocarbons, as gasoline and benzene <br /> which appear anomalous with respect to typical monitoring and sampling events. It <br /> remains the opinion of Aegis and Shell Oil Company (Shell) that shallow groundwater <br /> does not contain petroleum hydrocarbons. Attachment 1 is a table of historical <br /> groundwater analytical data. <br /> Aegis, on behalf of Shell, request the SJCPHS/EHD consider no further action necessary <br /> at the subject site. In the event you do not grant this request, we propose the monitoring <br /> and sampling frequency of the site be reduced to annually. Unless Aegis receives <br /> notification from the SJCPHS/EHD, the next monitoring and sampling event would be <br /> scheduled for November 1994. <br /> 69-013H L7R �, <br />
