' Quarterly Report - First Quarter 2003 <br /> COUNTRY CLUB FOOD AND FUEL <br /> ' 1856 Country Club Boulevard, Stockton, California <br /> ' 1.0. INTRODUCTION <br /> At the request of Mr Phil Elder of Country Club Food and Fuel,Advanced GeoEnvironmental, Inc <br /> (AGE) has prepared this quarterly report for the property Iocated at 1856 Country Club Boulevard, <br /> Stockton, California (site) The objective of the work was to monitor dissolved petroleum <br /> ' hydrocarbon concentrations in ground water and to characterize ground water elevation, flow <br /> direction and hydraulic gradient on the site The site and the surrounding area are illustrated in <br /> Figure 1 On-site structures and monitoring well locations are illustrated on Figure 2 Site <br /> background information is provided in Appendix A <br /> ' 2 0. PROCEDURES <br /> Field procedures were performed in accordance with Central Valley Regional Water Quality Control <br /> ' Board(CVRWQCB)and San Joaquin County Environmental Health Department(EHD)guidelines <br /> for investigating underground storage tank(UST)sites and sampling ground water monitoring wells <br /> ' . At the request of Mr Mike Infurna of the EHD, Country Club Food and Fuel quarterly ground water <br /> monitoring events are coordinated to occur concurrently with ground water monitoring activities at <br /> ' the adjacent Sanchez property(1878 Country Club Boulevard) However,the concurrent monitoring <br /> of these two properties was not ascertained this quarter due to scheduling constraints <br /> ' 2 1 WELL MONITORING AND EVACUATION <br /> On 07 March 2003, ground water monitoring and sampling was performed on wells MWl through <br /> MW4 Prior to sampling, the depth to ground water was measured from the top of each well casing <br /> to the nearest 0 01-foot utilizing a Solinst water level meter The ground water elevation in each well <br /> ' was calculated by subtracting the measured depth to ground water from the surveyed casing elevation <br /> (Table 1) <br /> ' After water levels were measured, each monitoring well was purged of standing water utilizing a <br /> new, disposable bailer Approximately 6 5 to 7 0 gallons of water (a minimum of 3 casing-water <br /> volumes) were removed from each well Ground water temperature, pH and conductivity were <br /> ' measured at regular intervals during purging using an Oakton water analyzer Field sheets and data <br /> are included in Appendix B Purged water was stored on-site in labeled, 55-gallon DOT-approved <br /> drums pending proper disposal <br /> • <br /> ' Advanced GcoEnvironmental,Inc <br />
