INTRODUCTION <br /> In accordance with a request from Mr Ed Endlch of Top Filling Station, Advanced <br /> GeoEnvironmental,Inc (AGE)has prepared this Quarterly Report for 101 South Wilson Way(site), <br /> Stockton, California The location of the site and the immediately surrounding area are Illustrated <br /> on Figure 1 Site structures and monitoring well locations are shown on Figure 2 <br /> rThe objective of the work was to momtor dissolved petroleum hydrocarbon concentrations in ground <br /> water and to characterize ground water flow direction and gradient on the site This report is <br /> prepared in accordance with guidelines established by the San Joaquin County Public Health <br /> Services - Environmental Health Division (PHS-EHD) and by the Central Valley Regional Water <br /> Quality Control Board(CVRWQCB)for the investigation of underground storage tank (UST) sites <br /> A summary of previous investigations at the site was included in the Quarterly Report - October <br /> 1996, dated 22 November 1996, prepared by AGE <br /> 2.0. QUARTERLY MONITORING PROCEDURES <br /> 21 MONITORING WELL PURGE PROCEDURES <br /> On 11 June 1998,the depth to ground water was measured to the nearest 0 01 foot from the tops of <br /> the well casings in monitoring wells MW-I through MW-5,VW-IC, VW-2A and VW-3A utilizing <br /> a Sollnst water level meter Ground water elevations from MW-I through MW-5 were calculated <br /> I by subtracting the measured depth to ground water from the surveyed casing elevations (Table 1) <br /> Ground water elevations with respect to mean sea level were plotted and contoured on a scaled site <br /> map (Figure 3) <br /> IAfter water levels were measured, approximately 10 to 18 gallons of ground water(a minimum of <br /> three well volumes per well)were removed from wells MW-1 through MW-5,VW-1 C,VW-2A and <br /> I <br /> VW-3A utilizing a Grundfos Redi-Flo II submersible pump Temperature,pH and conductivity were <br /> measured at regular purge volume intervals from each well using an ICM Model 52200 water <br /> analyzer. Dissolved oxygen in purged water was measured at each well using a YSI Model 55 <br /> Dissolved Oxygen Meter at the conclusion of the purge process Field data and logs are presented <br /> in Appendix A Purged ground water was contamenzed in 55-gallon drums and was stored on-site <br /> in an area lacking general public access <br /> Advanced GeoEnvmron mental,Inc <br />
