I r ' <br />' Quarterly Report - Third and Fourth Quarter 2003 <br /> MOORE TRUCK LINES <br />' 3400 Newton Road, Stockton, California <br />' 1.0. INTRODUCTION <br />' At the request of Mr Eric Weilburg of Moore Truck Lines, Advanced GeoEnvironmental, IIIc <br /> (AGE) has prepared this quarterly report for the property located at 3400 Newton Road (site), <br /> Stockton,Cali forma The scope of work Included conducting two quarterly groundwater monitoring <br />' events and preparation of this report The site and the surrounding area are illustrated in Figure 1 <br /> On-site structures and well locations are illustrated on Figure 2 <br />' 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 2 and 3 <br /> of this report <br /> I <br /> 2.0. PROCEDURES <br /> I • <br /> Four ground water monitoring wells (MW-1 through MW-4) and domestic well DW-1 were <br /> monitored and sampled on 08 July 2003 and 12 December 2003 The field work was performed in <br /> Iaccordance with Central Valley Regional Water Quality Control Board (RWQCB) guidelines for <br /> investigations of underground storage tank (UST) sites <br /> I <br /> 2 1 WELL MONITORING AND EVACUATION <br /> IOn 08 July 2003 and 12 December 2003, a Solinst water level meter was used to measure the depth <br /> to ground water in monitoring wells MW-1 through MW-4 relative to the tops of the well casings <br />' <br /> (wellheads) After water levels were gauged,disposable plastic bailers were used to evacuate(purge) <br /> wells MW-2, MW-3 and MW-4 of a minimum of three casing-water volumes (approximately 5 <br /> gallons)of water,well MW-1 did not contain sufficient free-standing water for purging or sampling <br /> I at either monitoring event Temperature, pH, and conductivity were measured at regular intervals <br /> using an Oakton water analyzer The field data sheets are included in Appendix A Purged water was <br /> stored on site in 55-gallon drums <br /> 22 COLLECTION AND ANALYSIS OF GROUND WATER SAMPLES <br /> Water samples were collected from monitoring wells MW-2 through MW-4 using new plastic bailers <br /> after allowing the wells to achieve a mimmum 80% recovery of the pre-purge water volume In <br /> IAdvanced GeoEnvironmental,Inc <br /> I <br />
