INTRODUCTION At the request of Mr Robert McCarty of Plaza Liquors II,Advanced GeoEnvironmental,Inc (AGE) ' has prepared this quarterly report for the property located at 2420 West Turner Road, Lodi, California (site) The scope of work included the performance of a quarterly ground water monitoring event, submission of analytical data to the State Water Resources Control Board's ' GeoTracker information management system, and preparation of this report The site and the surrounding area are illustrated on Figure 1 On-site structures, soil borings, and monitoring well ' locations are illustrated on Figure 2 Site background information is summarized in Appendix A ' 2.0. PROCEDURES Field work was performed in accordance with guidelines established by the Central Valley Regional ' Water Quality Control Board(CVRWQCB)for the investigation of underground storage tank(UST) sites, and by the San Joaquin Environmental Health Department(EHD) for the sampling of ground water monitoring wells Monitoring wells MW-7 and MW-8 are sampled annually during the fourth ' . quarter at the request of the EHD ' 2 1 WELL MONITORING AND EVACUATION On 08 November 2005,the depth to ground water in monitoring wells MW-1 through MW-11 was ' measured from the top of each well casing to the nearest 0 01-foot utilizing a Solinst water level meter Ground water elevation in each well was calculated by subtracting the measured depth to ground water from the surveyed casing elevation (Table 1) ' After recordingwater level measurements, wells MW- through MW- 1 were purged b lowering g P g Y g ' and raising a%-inch outer diameter, length-discrete polyethylene hose equipped with a bail-valve water tip through the top chambers into the specific water-charged screened section A Waterra Hydro-Lift II pump equipped with a mechanical arm was utilized to surge each well with a ' polyethylene hose Approximately 3 75 to 6 gallons of water (a minimum of three casing-water volumes per well) were removed from wells MW-1 through MW-7 and MW-9, well MW-8 drew down after 2 5 gallons of water had been purged Approximately 44 and 45 gallons of water were ' removed from wells MW-10 and MW-11, respectively Ground water temperature, pH, and conductivity were measured at regular intervals for stabilization during purging using an Oakton water analyzer Field sheets and data are included in Appendix B Purged water was stored on-site ' in properly labeled Department of Transportation (DOT)-approved model 17H 55-gallon drums IAdvanced GeoEnvironmental,Inc I
