' Quarterly Report - First Quarter 2004 <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, 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 is illustrated In Figure 1 On- <br /> site structures and well locations are illustrated in 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 /> 1 <br /> 2 0. PROCEDURES <br /> 1 • y� <br /> Four groundwater monitoring wells (MW-1 through MW-4) and domestic well DW-1 were <br /> monitored and sampled on 12 March 2004 The field work was performed in accordance with <br /> 1 Central Valley Regional Water Quality Control Board (RWQCB) guidelines for investigations of <br /> underground storage tank (UST) sites <br />' <br /> 2 1 WELL MONITORING AND EVACUATION <br />' On 12 March 2004, a Solinst 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) wells MW-2, <br /> MW-3 and MW-4 of 6 50 to 7 25 gallons of water(a minimum of three casing-water volumes),well <br /> MW-1 did not contain sufficient free-standing water for purging or sampling 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 /> t Water samples were collected from monitoring wells MW-2 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 such that the well purge valve was <br /> 1 Advanced GeoEnvEronmental,Inc <br /> 1 <br />
