I <br /> QUARTERLY REPORT <br /> August 1996 <br />' Marlowe Properties <br /> 4648 East Waterloo Road <br />' Stockton, California <br />' 1.0. INTRODUCTION AND SCOPE OF WORK <br /> In accordance with the request of Mr Jonathan Marlowe of Marlowe Properties, Advanced <br />' GeoEnvironmental, Inc (AGE) has performed quarterly ground water monitoring activities at 4648 <br /> Waterloo Road, Stockton, California (the site) <br /> This report details the monitoring and sampling procedures performed on 08 August 1996 and <br /> presents the results of the laboratory analysis The objective of the sampling is to monitor <br /> concentrations of petroleum hydrocarbons in ground water at the site A description of previous <br /> investigations at the site was included in the Quarterly Report -April 1996, dated 12 June 1996, <br /> prepared by AGE The location of the site and the immediately suirounding area are illustrated on <br /> Figure 1 -Location Map A strictures and monitoring well locations on the site are shown on Figure <br /> 2 - Site Plan <br /> The monitoring and sampling was performed in accordance with San Joaquin County Public Health <br /> Services - Environmental Health Division (PHS-EHD) and Regional Water Quality Control Board <br /> (RWQCB) guidelines for the investigation of underground storage tank (UST) sites <br /> 2.0. PROCEDURES <br /> I21 MONITORING WELL PURGE PROCEDURES <br /> On 08 August 1996, the depth to ground water in each monitoring well was measured to the nearest <br /> 0 01 foot from the tops of the well casings utilizing a Solinst water level meter Relative ground water <br /> elevations were calculated by subtracting the depth to ground water from the relative casing <br /> elevations surveyed from a temporary benchmark (Table 1-Relative Ground Wates Elevations) <br /> Relative ground water elevations were plotted and contoured on a scaled site map, from which the <br /> ground water gradient was calculated (Figure 3- Relative Ground Water Elevation Map) <br /> After water levels were measured, a minimum of three well volumes of ground water was purged <br /> from each well using a Grundfos Redi-Flo II submersible pump Approximately five gallons of water <br /> was removed from MW-1, between sixty and seventy-five gallons of ground water were removed <br /> from wells MW-2 through MW-4 <br /> Temperature, pH and conductivity were measured at regular intervals from each well using an ICM <br /> model 52200 water analyzer Stabilization data and field logs are contained in Appendix A Purged <br /> ground water was stored in 55-gallon drums on-site in an area inaccessible to the general public <br />
