' Quarterly Report - Second Quarter 2005 <br /> FLAME MINI-MART <br />' 1301 West Kettleman Lane,Lodi, California <br />' 1.0, INTRODUCTION- <br /> At the request of Mr Pete Graffigna,Advanced GeoEnvlronmental, Inc (AGE) has prepared this <br />' quarterly report for 1301 West Kettleman Lane (the site), Lodi, California The scope of work <br /> included conducting a quarterly ground water monitoring event and preparation of this report, the <br />' objective of the work was to assess, characterize and monitor dissolved petroleum hydrocarbon <br /> concentrations in ground water and to calculate ground water flow direction and gradient on-site The <br /> site setting is illustrated on Figure 1 Site structures and monitoring well locations are depicted on <br />' Figure 2 <br /> This report has been prepared in accordance with guidelines issued by the Central Valley Regional <br />' Water Quality Control Board (CVRWQCB) for Investigation of underground storage tank (UST) <br /> sites <br />' History and findings from previous Investigations at the site are summarized In Appendix A <br />'• 2.0. PROCEDURES <br /> Seven monitoring wells(MW-1 through MW-7)were monitored,purged and sampled In May 2005 <br />' Field work was performed in accordance with San Joaquin County Environmental Health <br /> Department (EHD) guidelines for sampling ground water monitoring wells and CVRWQCB <br /> guidelines for the Investigation of UST sites <br />' 21 WELL MONITORING AND PURGE PROCEDURES <br /> On 09 May 2005 the depth to-ground water In the seven monitoring wells were measured from the <br />' top of each well casing to the nearest 0 01-foot utilizing a Solinst water level meter, ground water <br /> elevations for each well were calculated by subtracting the measured depth to ground water from the <br /> surveyed casing elevation (Table 1) After water levels were measured, approximately 5 5 to 6 5 <br /> I gallons of water (a minimum of 3 casing-water volumes per well) were purged from monitoring <br /> wells MW-1 through MW-6 and approximately 18 gallons of water were removed from well MW-7 <br /> using a Watera hydrolift pump and dedicated tubing Ground water temperature,pH and conductivity <br /> were'measured at regular intervals during purging using an Oakton water analyzer Field sheets and <br /> data are included in Appendix B Purged water was stored in properly labeled Department of <br /> Transportation (DOT)-approved 55-gallon drums and stored on-site <br /> I <br /> Advanced GeoEnvironmental,Inc <br />
