Date. October 29,2003 <br /> Quarter: 3T'Quarter,2003 <br /> DISCUSSION: <br /> Total petroleum hydrocarbons as gasoline (TPHg),benzene, ethylbenzene, and methyl tert-butyl ether(MtBE) were <br /> reported above method detection limits in groundwater samples collected from site wells this quarter Analyte <br /> concentrations were generally consistent with historic data Groundwater elevation in site wells decreased relative to <br /> the previous monitoring event The inferred direction of groundwater flow across the site was northeast at an <br /> average hydraulic gradient of 0 0015 feettfoot <br /> The soil vapor extraction (SVE) system did not run during the reporting period The air sparge (AS) system <br /> operated from January 22 through the end of the third quarter Appendix A contains historical SVEIAS system <br /> operational data <br /> This report is based on data, site conditions, and other information that are generally applicable as of the date of the <br /> report,and the conclusions and recommendations herein are therefore applicable only to that time frame <br /> TABLES <br /> Table 1 Groundwater Elevation and Analytical Data <br /> Table 2 Fuel Oxygenates Analytical Data <br /> Table 3 Groundwater Gradient Data <br /> FIGURES <br /> • Figure I Groundwater Elevation Contours <br /> Figure 2 Groundwater Analytical Summary <br /> APPENDICES <br /> Appendix A Remedial System Performance Evaluation <br /> Appendix B Field and Laboratory Procedures <br /> Appendix C Laboratory Analytical Reports,Chain-of-Custody Documentation,and Field Data Sheets <br /> Appendix D GeoTracker Upload Confirmation <br /> K 1Wprucm0 BP ARC01020931Quarter1y\3 QTR 0312043 GWMR 3Q03 dm Page 2 <br />
