1 ' <br /> • Quarterly Report - Third Quarter 2001 <br />' FLAME MINI-MART <br /> 1301 West Kettleman Lane <br /> Lodi, California <br /> I.O. INTRODUCTION <br />' At the request of Mr Graffigna of Flame Mini-Mart,Advanced GeoEnvironmental, Inc (AGE)has <br /> prepared this quarterly report for the site at 1301 West Kettleman Lane,Lodz, California The scope <br />' of work Included monitoring and sampling three of four ground water monitoring wells for <br /> petroleum hydrocarbons At the direction of Mr Harlin Knoll of the San Joaquin County Public <br /> Health Services-Environmental Health Division (PHS-EHD), only depth to ground water was <br />' recorded for the fourth well (MW-4), which will be sampled every other quarter <br /> All four wells have been utilized for monitoring the petroleum hydrocarbon-impact to ground water <br />' associated with an unauthorized release of petroleum hydrocarbons from a UST system formerly <br /> located at the site Quarterly monitoring and reporting was required by the PHS-EHD by letter dated <br /> 01 November 1999 The site setting is illustrated on Figure 1 Locations of structures, bonngs, and <br />' monitoring wells are Illustrated on Figure 2 <br /> Site history and findings from previous investigations at the site are summarized in the AGE- <br /> tprepared Preliminary Site Assessment Work Plan, dated 30 June 1999 <br />' 2.0. PROCEDURES <br />' The work was performed in accordance with PHS-EHD and California Regional Water Quality <br /> Control Board- Central Valley Region guidelines for sampling ground water monitoring wells and <br /> investigating underground storage tank (UST) sites <br /> 2 1 WELL MONITORING AND EVACUATION <br /> On 28 September 2001, a Solinst water level meter was used to measure the depth to ground water <br /> in all four monitoring wells relative to the tops of the well casings After the depth-to-ground water <br /> measurements were collected,three of the monitoring wells(MW-1 to MW-3)were evacuated using <br /> disposable polyvinyl chloride(PVC)bailers Between 5 to b gallons ofwater were purged from each <br /> of the monitoring wells, equivalent to three casing-water volumes per well <br /> I Temperature, H and conductive were measured at 1--gallon intervals, using an Oakton water <br /> p conductivity g g <br /> analyzer to monitor pH, temperature and conductivity of the purged water, the field data logs are <br /> Iprovided in Appendix A Purge water was temporarily stored on-site in 55-gallon drums <br /> ' C <br /> Advanced GeoEnvironmentaI,Inc <br /> I <br />
