} Approximate Depth to Groundwater 36 00 to 38 14 feet bgs (3116101) Direction of Groundwater Flow East-Northeast (each monitoring event) Groundwater Gradient 0 0019 fVft(3116101) DISCUSSION TPHG and BTEX were detected in the sample collected from monitoring well MW-1 TPHG and BTEX were not detected in any of the other samples MTBE was detected in the samples collected from wells MW-1, MW-4, VW-1B, VW-26, and VW-3B at concentrations ranging from 2,910 ug/L (MW-1) to 9 12 pg/L (VW-3B) TAME was detected in the samples collected from monitoring wells MW-1 (24 6 µg/L) and MW-4 (3 78 �Lg/L) Groundwater samples were not collected from wells VW-1A, VW-2A, and VW-3A due to insufficient quantities of water in the wells Groundwater elevations increased approximately one foot since the previous quarter Groundwater contour maps generated from each monitoring event illustrate that groundwater flow direction at the site was towards the east-northeast at a generally consistent gradient (0 0019 ft/ft to 0 0026 ft/ft) ATTACHMENTS • Table 1 Groundwater Monitoring Data • Table 2 Groundwater Analytical Results for Oxygenates • Table 3 Groundwater Elevation Data • Figure 1 Site Location Map • Figure 2 Groundwater Elevation Contours (1/16/01) • Figure 3 Groundwater Elevation Contours (2112/01) • Figure 4 Groundwater Elevation Contours (3116/01) • Figure 5 Groundwater Analytical Summary(1st Quarter 2001) • Appendix A Field Data Sheets • Appendix B Sampling and Analysis Procedures • Appendix C Certified Analytical Reports and Chain-of-Custody Records • C 1ARC0\21861QTRLY1200112186Q101 doc Delta 514/01
