Quarterly Report - Fourth Quarter 2002 <br /> FORMER FISCO WAREHOUSE (Howard Lenz Property) <br /> 1.648 Shaw Road, Stockton, California <br /> 1.0. INTRODUCTION <br /> I At the request of Mr Peter Lenz of Innovative Beverage Brokers,Advanced GeoEnvironmental,Inc <br /> (AGE) has prepared this quarterly report for the property located at 1648 Shaw Road, Stockton, <br /> California The site and the surrounding area are illustrated in Figure 1 Structures,boring and well <br /> E locations are illustrated on Figure 2 Background information is summarized in the AGE-prepared <br /> Preliminary Site Investigation Report, dated 30 December 1997 <br /> 2.0. PROCEDURES <br /> Field work was performed in accordance with guidelines issued by San Joaquin County <br /> Environmental Health Department (EHD) for the sampling of ground water monitoring wells and <br /> Central Valley Regional Water Quality Control Board (CVRWQCB) guidelines for investigation <br /> of underground storage tank (UST) sites <br /> 2 1 WELL MONITORING, EVACUATION AND SAMPLING <br /> On 07 November 2002, AGE attempted to measure the depth to ground water in monitoring wells <br />' MWl through MW7 relative to the tops of the well casings utilizing a Solinst water level meter, <br /> however,depth measurements were not possible as all seven wells had no measurable water in them <br /> (Appendix A) Consequently, these wells cannot be purged or sampled Field sheets and data are <br /> included in Appendix A <br /> 3.0. FINDINGS <br />' Ground water elevation,flow direction,and gradient cannot be determined from field data collected <br /> on 07 November 2002 because there was no measurable water in any of the seven ground water <br /> monitoring wells In addition, the contaminant impact to ground water could not be quantified <br />' because ground water samples cannot be collected <br /> 4.0. SUMMARY AND CONCLUSIONS <br /> Based on the data collected from the site, AGE finds <br />' Groundwater elevations at the site decreased in wells MW 1 through MW7 an average of at <br /> least 2 8 feet(to below the screened depth of monitoring wells MW-4 through MW-7)since <br /> the third quarter 2002 monitoring event <br /> Advanced GeoEnvironmental,Inc <br />
