• Quarterly Report - Fourth Quarter 2003 <br /> FLAME MINI-MART <br />' 1301 West Kettleman Lane, Lodi, California <br />' 1.0. INTRODUCTION <br /> Advanced GeoEnvironmental, Inc (AGE) has prepared this quarterly report for 1301 West <br />' Kettleman Lane (the site), Lodi, California The scope of work Included conducting a quarterly <br /> ground water monitoring event and preparation of this report, the objective of the work was to <br />' assess, characterize and monitor dissolved petroleum hydrocarbon concentrations in ground water <br /> and to calculate ground water flow direction and gradient on the site The site setting is Illustrated <br /> in Figure 1 Site structures and monitoring well locations are depicted In Figure 2 <br />' This report has been prepared in accordance with guidelines Issued by the California Regional Water <br /> Quality Control Board(RWQCB)-Central Valley Region for investigation of underground storage <br />' tank(UST) sites Site history and findings from previous investigations at the site are summarized <br /> In the AGE-prepared Preliminary Site Assessment Work Plan, dated 30 June 1999 <br /> I2.0. PROCEDURES <br /> l <br /> Six monitoring wells (MW-1 through MW-4, MW6 and MW-7) were monitored, purged and <br /> ie sampled in November 2003 Field work was performed in accordance with San Joaquin County <br /> Environmental Health Department (EHD) guidelines for sampling ground water monitoring wells <br /> and Central Valley Regional Water Quality Control Board (CVRWQCB) guidelines for <br /> investigations of underground storage tank (UST) sites <br /> 2 1 WELL MONITORING AND PURGE PROCEDURES <br /> The depth to ground water in the six monitoring wells was measured from the top of each well <br /> casing to the nearest 0 01-foot utilizing a Solinst water level meter Ground water elevation in each <br /> I well was calculated by subtracting the measured depth to ground water from the surveyed casing <br /> elevation (Table 1) <br /> After water levels were measured,approximately 5 5 to 6 0 gallons of water(a minimum of 3 casing- <br /> water volumes per well)were purged from monitoring wells MW-1 through MW-4 and MW-6 and <br /> approximately 18 gallons of water were removed from well MW-7 using a Watera hydrolift pump <br /> and dedicated tubing Ground water temperature, pH and conductivity were measured at regular <br /> Intervals during purging using an Oakton water analyzer Field sheets and data are included in <br /> Appendix A Purged water was stored in properly labeled DOT-approved 55-gallon drums and stored <br />' on-site <br /> 0 <br /> IAdvanced GeoEnviron mental,Inc <br />
