IQuarterly Report - Second Quarter 2002 <br /> • MOORE TRUCK LINES <br />' 3400 Newton Road, Stockton, California <br />' 10. INTRODUCTION <br /> I At the request of Mr Eric Weilburg of Moore Truck Lines, Advanced GeoEnvironmental, Inc <br /> (AGE) has prepared this quarterly report for the property located at 3400 Newton Road (site), <br /> Stockton, California The scope of work included conducting a quarterly ground water monitoring <br />' event and preparation of this report The site and the surrounding area are illustrated in Figure 1 On- <br /> site structures and well locations are illustrated on Figure 2 <br /> I Background information,well installation and ground water monitoring procedures for the site are <br /> summarized in the AGE-prepared documents, Preliminary Investigation and Evaluation Report, <br /> dated 15 September 1999, Monitoring Well Installation Work Plan, dated 23 May 2001 and <br />' Monitoring Well Installation & Quarterly Report- Third Quarter 2001, dated 26 November 2001 <br /> Ground water sample data from November 1999 to the present are summarized in Tables 3 and 4 <br /> of this report <br /> 1 <br /> 2.0. PROCEDURES <br />' Four ground water monitoring wells (MW-1 through MW-4) and domestic well DW-1 were <br /> monitored and sampled on 10 June 2002 Field work was performed in accordance with Central <br />' Valley Regional Water Quality Control Board (RWQCB) guidelines for investigations of <br /> underground storage tank (UST) sites <br /> I <br /> 2 1 WELL MONITORING AND EVACUATION <br />' On 10 June 2002, a Sohnst water level meter was used to measure the depth to ground water in <br /> monitoring wells MW-1 through MW-4 relative to the tops of the well casings (well heads) After <br />' water levels were gauged, disposable plastic bailers were used to evacuate (purge) MW-2, MW-3 <br /> and MW-4 of a minimum of three casing-water volumes(approximately 7 gallons)of water,MW-1 <br /> was bailed dry after approximately 1 66 gallons had been removed Temperature, pH, and <br />' conductivity were measured at regular intervals using an Oakton water analyzer The field data sheets <br /> are included in Appendix A Purged water was stored on site in 55-gallon drums <br />' 2 2 COLLECTION AND ANALYSIS OF GROUND WATER SAMPLES <br />' Water samples were collected from monitoring wells MW-1 through MW-4 using new plastic bailers <br /> after allowing the wells to achieve a minimum 80% recovery of the pre-purge water volume In <br /> addition, a water sample was collected from domestic well DW-1 after the well purge valve was <br />' Advanced GeoEnvoronmental,Inc <br />
