Quarterly Report - 'Third Quarter 2002 <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 GeoEnvlronmental,Inc <br /> (AGE) has prepared this quarterly report for the property located 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 gradient on the site The site and the surrounding area are illustrated in Figure 1 On- <br /> site structures and monitoring well locations are illustrated on Figure 2 <br /> ' Background information and ground water monitoring procedures for the site are described in the <br /> AGE-prepared work plan titled Monitoring Well Installation Work Plan, dated 29 December 1999 <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(18 78 Country Club Boulevard) <br /> ' 2 1 WELL MONITORING AND EVACUATION <br /> ' On 12 August 2002,ground water monitoring and sampling were performed on wells MW 1 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 gauged, each monitoring well was purged of standing water utilizing new, <br /> disposable bailers Approximately 6 1 to 6 6 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 A Purged water was stored on-site in labeled, 55-gallon DOT-approved <br /> ' drums pending proper disposal <br /> Advanced GeoEnvironmental,Inc <br /> 1 <br />
