INTRODUCTION AND SCOPE OF WORK <br /> i At the request of Mr Paul Sidhu, Advanced GeoEnvironmental, Inc (AGE) has prepared this <br /> quarterly report for the site located at 3032 E Waterloo Road, Stockton, California (site) The <br /> location of the site is illustrated in Figure 1 The locations of structures and monitoring wells on the <br /> i site are depicted in Figure 2 The scope of work reported herein includes a quarterly ground water <br /> monitoring event performed on 10 August 2001 <br /> i Site history and findings from previous investigations and monitoring events at the site are detailed <br /> in AGE's report titled Preliminary Investigation and Evaluation Report, dated 14 December 2000 <br /> Historical ground water monitoring results are included in the tables of this report <br /> 2.0. PROCEDURES <br /> Tasks andwere rocedures for this investigation completed in accordance with the <br /> P g <br />�. PHS-EHD-approved Preliminary Site Assessment Work Plan, dated 12 October 1999 and prepared <br /> by AGE <br /> This report is prepared in accordance with guidelines established by the California Regional Water <br /> Quality Control Board (CRWQCB) - Central Valley Division for subsurface investigation of <br /> underground storage tank (UST) sites <br /> 2 1 QUARTERLY MONITORING AND SAMPLING PROCEDURES <br /> IOn 10 August 2001, depth to ground water was measured in each well from the top of the well <br /> casing to the nearest 0 01-foot utilizing a Solinst water level meter The ground water elevation in <br /> I each well at the site was calculated by subtracting the measured depth to ground water from the <br /> surveyed well-head elevation (Table 1) Ground water elevations were later plotted and contoured <br /> on a scaled site map <br /> After water levels were measured,approximately 4 to 5 gallons of ground water(a mimmurn of three <br /> casing water-volumes per well) were removed from wells MW-1, MW-3 and MW-4 utilizing <br /> Idisposable polyethylene bailers Monitoring well MW-2 was not purged or sampled due to the <br /> presence of free product Temperature, pH and conductivity were measured for stabilization at <br /> regular purge-volume intervals using an Oakton water analyzer Field data and logs are included with <br /> Appendix A Purged ground water was containerized in 55-gallon drums and was stored on-site in <br /> • an area lacking general public access <br /> Advanced GeoEnvironmental,Inc <br />
