INTRODUCTION <br /> ' At the request of Mr Phil Elder of Country Club Food and Fuel,Advanced GeoEnvironmental,Inc w <br /> I (AGE)has prepared this quarterly report for the property located at 1856 Country Club Boulevard, <br /> Stockton, Califorma.(site) The objective of the work was to monitor dissolved fuel additive methyl <br /> I tertiary butyl ether (MTBE) concentrations to ground water and to characterize ground water <br /> elevation, flow direction and hydraulic gradient on the site The site and the surrounding area are <br /> illustrated in Figure 1 On-site structures and monitoring well locations are illustrated on Figure 2 <br /> Site background information Is provided in Appendix A <br /> 2.0. PROCEDURES <br /> I <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 groundwater 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 /> I a , <br /> 2 1 WELL MONITORING AND EVACUATION <br /> On 22 May 2003, ground water monitoring and sampling was performed on wells MW1 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 /> I <br /> After water levels were measured, each monitoring well was purged of standing water utilizing a <br /> new, disposable bailer Approximately 7 0 to 7 5 gallons of water (a minimum of 3 casing-water <br /> I 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 m labeled, 55-gallon DOT-approved <br /> drums pending proper disposal <br /> I , <br /> Advanced GeoEnvironmento],Inc <br />
