' Quarterly Report - Third Quarter 2005 <br /> PLAZA LIQUORS II <br />' 2420 West Turner Road,Lodi, California <br /> 1.0. INTRODUCTION <br /> I <br /> At the request of Mr Robert McCarty of Plaza Liquors II,Advanced GeoEnvironmental,Inc (AGE) <br />' has prepared this quarterly report for the property located at 2420 West Turner Road, Lodi, <br /> California (site) The scope of work included the performance of a quarterly ground water <br /> monitoring event and preparation of this report The site and the surrounding area are illustrated on <br />' Figure 1 On-site structures, soil borings, and monitoring well locations are illustrated on Figure 2 <br /> Site background information is summarized in Appendix A <br /> I <br /> 2.0. PROCEDURES <br />' Field work was performed in accordance with guidelines established by the Central Valley Regional <br /> Water Quality Control Board(CVRWQCB)for the investigation of underground storage tank(UST) <br />' sites, and by the San Joaquin Environmental Health Department(EHD)for the sampling of ground <br /> water monitoring wells Monitoring wells MW-7 and MW-8 are sampled annually during the fourth <br /> quarter at the request of the EHD <br /> 2 1 WELL MONITORING AND EVACUATION <br /> On 08 August 2005, the depth to ground water in monitoring wells MW-1 through MW-11 was <br /> measured from the top of each well casing to the nearest 0 01-foot utilizing a Solmst water level <br />' meter Ground water elevation in each well was calculated by subtracting the measured depth to <br /> ground water from the surveyed casing elevation (Table 1) <br />' After recording water level measurements,wells MW-1 through MW-6 and MW-9 through MW-11 <br /> were purged by lowering and raising a $/e-inch outer diameter, length-discrete polyethylene hose <br /> equipped with a ball-valve water tip through the top chambers into the specific water-charged <br /> screened section A Waterra Hydro-Lift II pump equipped with a mechanical arm was utilized to <br /> surge each well with a polyethylene hose Approximately 4 to 6 gallons of water (a minimum of <br />' three casing-water volumes per well)were removed from wells MW-1 through MW-6 and MW-9, <br /> approximately 45 gallons of water were removed from wells MW-10 and MW-11 Ground water <br /> temperature,pH,and conductivity were measured at regular intervals for stabilization during purging <br />' using an Oakton water analyzer Field sheets and data are included in Appendix B Purged water was <br /> stored on-site in properly labeled Department of Transportation (DOT)-approved model 17H <br /> 55-gallon drums <br /> 1 <br /> Advanced GeoEnvironmental,Inc <br />
