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 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 Site background information <br /> ' 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) <br /> 2 1 WELL MONITORING AND EVACUATION <br /> ' On 21 November 2002 ground water monitoring and sampling were performed on wells MW1 <br /> �' g <br /> through MW4 Prior to sampling,the depth to ground water was measured from the top of each well <br /> ' casing to the nearest 0 01-foot utilizing a Solinst water level meter The ground water elevation in <br /> each well was calculated by subtracting the measured depth to ground water from the surveyed <br /> casing elevation (Table 1) <br /> After water levels were gauged,each monitoring:well was purged of standing water utilizing a new, <br /> ' disposable bailer Approximately 6 0 to 6 2 gallons of water(a minimum of 3 casing-water volumes) <br /> were removed from each well Ground water temperature, pH and conductivity were measured at <br /> regular intervals during purging using an Oakton water analyzer Field sheets and data are included <br /> ' in Appendix A Purged water was stored on-site in labeled,55-gallon DOT-approved drums pending <br /> proper disposal <br /> ' Advanced CeoEnvironmental,Inc <br />
