d ct <br /> Quarterly Report -Third Quarter 2003 <br /> MEL BOKIDES PETROLEUM, INC. <br /> 444 Mossdale Road, Lathrop, California <br /> 1.0. INTRODUCTION <br /> At the request of Mr Nick Bokides of Mel Bokides Petroleum Inc ,Advanced GeoEnvironmental, <br /> Inc (AGE)has prepared the enclosed report for the former Mel Bokides Petroleum facility located <br /> at 444 Mossdale Road, Lathrop, California (the site) The scope of work included gauging and <br /> sampling of the ground water monitoring well network on the site and preparation of this report The <br /> site setting is illustrated on Figure 1 Site structures,previous bormgs and monitoring well locations <br /> are depicted on Figure 2 <br /> The field work was performed in accordance with Central Valley Regional Water Quality Control <br /> Board(CV-RWQCB)and San Joaquin County Environmental Health Department(EHD)guidelines <br /> for subsurface investigations of underground storage tank(UST)sites and ground water monitoring <br /> well sampling procedures, respectively The site history and a description of work previously <br /> performed at the site were presented in the AGE-prepared Preliminary Investigation and Evaluation <br /> Report (PIER), dated 01 March 2000 <br /> 2.0. PROCEDURES <br /> On 05 September 2003, ground water momtormg and sampling were performed at the site on wells <br /> MW-1 through MW-5,in addition,a ground water sample was collected from the domestic well on- <br /> site <br /> 2 1 WELL MONITORING AND EVACUATION <br /> A Sollnst water level meter was used to measure the depth to ground water In monitoring wells <br /> MW-I through MW-5 After depth to ground water measurements were obtained, approximately 7 <br /> to 7 75 gallons ofwater were removed from each well(a minimum of 3 casing-water volumes)usmg <br /> dedicated, disposable bailers Temperature, pH and conductivity of purged ground water were <br /> measured at 1-gallon intervals using an Oakton water analyzer The field data sheets are Included <br /> in Appendix A <br /> Purged water was temporarily stored on--site in 55-gallon DOT-approved drums pending proper <br /> disposal Following purging, the depth to ground water was measured to ensure that a minimum of <br /> 80%well-volume recharge had been achieved prior to sampling <br /> Advanced GeoEnvironmental,Inc <br />
