I ' Quarterly Report - First Quarter 2006 • PLAZA LIQUORS II ' 2420 West Turner Road,Lodi, California ' 1.0. 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 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(EMD) 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 1 • 2 1 WELL MONITORING AND EVACUATION 1 On 08 February 2006, 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 1 meter Ground water elevation in each well was calculated by subtracting the measured depth to ground water from the surveyed casing elevation (Table 1) 1 After recording water level measurements,wells MW-1 through MW-6 and MW-9 through MW-11 were purged by lowering and raising a 5/s-inch outer diameter, length-discrete polyethylene hose equipped with a ball-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 5 to 7 gallons of water (a minimum of three casing-water volumes per well)were removed from wells MW-1 through MW-6 and MW-9, approximately 43 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 • Advanced GeoEnvironmenw,Inc 1
