I <br /> I <br /> . Ground Water Monitoring Report - First Quarter 2001 <br />' PLAZA LIQUORS 1Q <br /> 2420 West Turner Road, Lodi, California <br />' 1 0 INTRODUCTION <br />' At the request of Mr Robert McCarty,Advanced Geo Environmental, Inc (AGE) has prepared this <br /> quarterly report for the property located at 2420 West Turner Road, Lodi, California The site and <br /> the surrounding area are Illustrated in Figure I On-site structures and monitoring well locations are <br />' illustrated on Figure 2 Background information and ground water monitoring procedures for the site <br /> are summarized In AGE's work plan titled Prehmmary Sate Assessment Work Plan, dated 19 <br /> November 1999 The objective of the work was to monitor dissolved petroleum hydrocarbon <br /> rconcentrations In ground water and to characterize ground water flow direction and gradient on the <br /> site <br /> 2.0. PROCEDURES <br /> rField work and report preparation are In accordance with guidelines established by the San Joaquin <br /> County Public Health Services - Environmental Health Division (PHS-EHD) and by the Central <br />�. Valley Regional Water Quality Control Board (CVRWQCB) for sampling ground water monitoring <br /> wells and investigation of underground storage tank (UST) sites <br /> I2 1 MONITORING WELL PURGE PROCEDURES <br /> On 03 April 2001, ground water monitoring and sampling was performed on wells MWI 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 Soilnst water level meter Ground water elevations in each well <br /> r were calculated by subtracting the measured depth to ground water from surveyed casing elevations <br /> (Table 1) <br /> After water levels were gauged, a two-stage submersible pump was used to purge each monitoring <br /> well of standing water Approximately 9 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 /> rregular 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 <br /> r <br /> 22 COLLECTION OF GROUND WATER SAMPLES <br /> rWater samples were collected from each purged well using new disposable plastic bailers Each <br /> water sample was transferred Into one 1-liter amber bottle without sample preservative and three <br /> r40-m1 VOA vials containing 0 5 ml 18% hydrochloric acid as a sample preservative After <br /> Advanced GeoEnvironmental,Inc <br /> r <br />
