CAMBRIA <br /> The door-to-door survey results are included in Table 4, available well information is <br /> summarized on Table 2, and the well locations are plotted on Figure 1 Survey questionnaires <br /> are included as Appendix F <br /> Surface Water Bodies• A seasonal stream is located approximately 1,230 feet northeast of the <br /> subject site and the Mokelumne Aqueduct is located approximately 1,760 feet northwest of the <br /> subject site(Figure 1) <br /> CONCLUSIONS <br /> } TPHg and BTEX have not been detected in soil or groundwater beneath the site (except for a <br /> 0 130 ppm xylene detection in shallow soil beneath the northwestern dispenser) These <br /> constituents are delineated in soil and groundwater and do not appear to be constituents of <br /> concern at this site <br /> Soil results from boring S13-2, well boring MW-2, and well borings MW4 through MW-6 <br /> delineate fuel oxygenates laterally to the north,east, and south in soil beneath the site <br /> MTBE and TAME were detected in groundwater samples collected from wells MW-2 and <br /> MW-3 Wells MW-4 through MW-6 define the lateral extent of MTBE north (cross-gradient), <br /> south(cross-gradient), and northeast(down-gradient)of the site <br /> The receptor survey indicates that there are several domestic and/or irrigation wells located <br /> within 500 feet of the subject site The receptor survey also identified two surface water bodies, <br /> however, because they are over 1,000 feet from the subject, they are unlikely to be impacted by <br /> site activities Groundwater flow direction data from the third quarter 2002, indicates that <br /> groundwater beneath the subject site flows towards the east and northeast This suggests that the <br /> wells on Hammer Lane (including the closest well 160 feet from the site) are up-gradient of the <br /> site Groundwater analytical data from monitoring wells MW-4 and MW-5,located at the site's <br /> northern boundary, delineate fuel oxygenates onsite Therefore it is unlikely that any wells on <br /> Moreland Street, north of Hammer Lane, would be impacted by fuel oxygenates originating on <br /> the subject site <br /> 4 i <br /> 0953 <br />
