Date July 30,2003 <br /> Quarter 2°¢Quarter,2003 <br /> DISCUSSION: <br /> Total petroleum hydrocarbons as gasoline (TPHg), benzene, and MtBE were reported in groundwater samples <br /> collected from site monitoring wells this quarter Analyte concentrations were generally consistent with historic data <br /> with the following exceptions TPHg and MtBE concentrations increased in VW-3B relative to historic data,MtBE <br /> concentrations increased in MW-1 but are within historic ranges,benzene concentrations continue a decreasing trend <br /> in MW-1 All other analytes were reported as below Iaboratory detection limits Groundwater elevations in wells <br /> across the site generally increased relative to the previous quarter The inferred groundwater flow direction was toa <br /> the east/northeast at an average gradient of 0 01 feet/foot iS � s <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 I Groundwater Elevation and Analytical Data <br /> Table 2 Fuel Oxygenates Analytical Data <br /> FIGURES <br /> Figure I Groundwater Elevation Contours <br /> Figure 2 Groundwater Analytical Summary <br /> APPENDICES <br /> • Appendix A Field and Laboratory Procedures <br /> Appendix B Laboratory Analytical Reports,Cham-of-Custody Documentation, and Field Data Sheets <br /> K XWProcess\15 BP ARC01021861Quvner1yV QTR 03\2186 GWMR 2Q03 do Page 2 <br />
