1 <br /> Ground Water Monitoring Report - Fourth Quarter 2000 <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 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 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 Public Health Services - Environmental Health <br /> Division (PHS-EHD) guidelines for subsurface investigations of underground storage tank (UST) <br /> sites <br /> 2 1 MONITORING WELL PURGE PROCEDURES <br /> tOn 18 October 2000, ground water monitoring and sampling was 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, a submersible pump was used to purge each monitoring well of <br /> standing water Approximately 6 gallons of water (minimum of 3 casing-water volumes) were <br /> ' removed from each well Ground water temperature, pH and conductivity were measured at regular <br /> intervals during purging using a Hydac water analyzer Field sheets and data are included in <br /> Appendix A Purged water was stored on-site in labeled, 55-gallon DOT-approved drums <br /> 22 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 and three 40-m1 VOA vials containing 0 5 <br /> Advanced GeoEnvironmental,Inc <br />
