. Quarterly Report - First Quarter 2000 <br /> MOORE TRUCK LINES <br />' 3400 Newton Road <br /> Stockton, California <br />' 1.0. INTRODUCTION <br />' At the request ofMr Weilburg ofMoore Truck Lines,Advanced GeoEnvironmental,Inc (AGE)has <br /> prepared this Quarterly Report for the site at 3400 Newton Road, Stockton, California The scope <br /> of work included monitoring and sampling one ground water monitoring well(MW-1)and sampling <br />' one domestic well (DW-1) for petroleum hydrocarbons Monitoring well MW-1 was utilized for <br /> monitoring petroleum hydrocarbon-impacted ground water associated with an unauthorized release <br /> of petroleum hydrocarbons from USTs formerly located near the truck maintenance and repair shop <br />' building Domestic well DW-1 is utilized for on-site water and is located down to cross gradient <br /> from the former UST area and is the closest receptor The preparation of this report was required by <br /> the San Joaquin County Public Health Services-Enviromnental Health Division (PHS-EHD) to <br />' document and update site status The site setting is illustrated on Figure 1 Locations of structures, <br /> borings, domestic wells, and the monitoring well on the site are illustrated on Figure 2 Locations <br /> of structures and monitoring wells on adjacent sites are illustrated on Figure 3 <br />' Site history and findings from previous investigations at the site are detailed in the Preliminary <br /> Investigation and Evaluation Report- 15 September 1999 (PIER) prepared by AGE <br /> 2.0. PROCEDURES <br />' The work was performed in accordance with - <br /> p San Joaquin County PHS EHD and Central Valley <br />' Regional Water Quality Control Board guidelines for investigation of underground storage tank <br /> (UST) sites <br /> 21 MONITORING WELL PURGE PROCEDURES <br /> 4 <br />' On 15 February 2000, a Solinst water level meter was used to measure the depth to ground water in <br /> monitoring well MW-1 relative to the top of the well casing After the ground water depth <br /> measurement was collected, monitoring well MW-1 was purged using a polyvinylchloride (PVC) <br /> bailer The well was purged dry prior to sampling Approximately 6 gallons ofwater were evacuated <br /> from the monitoring well, equivalent to more than three well-casing volumes <br /> Temperature,pH and conductivity were measured at 2-gallon intervals,using an ICM model 52200 <br /> water analyzer to monitor stabilization of these ground water parameters The field data are <br /> summarized in a table and, along with the field data logs, are included in Appendix A Purged water <br /> is temporarily being stored on-site in 55-gallon drums <br /> I <br /> Advanced GeoEnvironmental,Inc <br />
