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 site and the surrounding area are illustrated in Figure 1 On-site <br /> structures and monitoring well locations are illustrated on Figure 2 Background information and <br /> ' ground water monitoring procedures for the site are described in the AGE-prepared work plan titled <br /> Monitoring Well Installation Work Plan, dated 29 December 1999 <br /> ' The objective of the work was to monitor dissolved petroleum hydrocarbon concentrations in ground <br /> water and to characterize ground water elevation, flow direction and gradient on the site <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 /> ' 2 1 WELL MONITORING AND EVACUATION <br /> On 15 January 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 Ground water elevations in each well <br /> were calculated by subtracting the measured depth to ground water from surveyed casing elevations <br /> (Table 1) <br /> After water levels were gauged, each monitoring well was purged of standing water utilizing new, <br /> ' disposable bailers Approximately 7 to 7 5 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 /> 1 <br /> 2 2 COLLECTION OF GROUND WATER SAMPLES <br /> Water samples were collected from each purged well using new disposable plastic bailers Each <br /> water sample was transferred into one 1-liter amber bottle with no sample preservative and into three <br /> Advanced GeoEnvironmental,Inc <br />
