. DISCUSSION <br /> MTBE was detected in the samples collected from monitoring wells MW-1 (48 µglL), MW-2 (43 µg/L), and <br /> MW-3 (0 62 gg/L), xylenes (1 4 µg/L) was detected in the sample from well MW-1, and 1,2-DCA was <br /> detected in the samples from wells MW-2 (0 98 gg/L) and MW-3 (0 50 µglL) TPHG, benzene, toluene, <br /> ethylbenzene, ETRE, D1PE, TAME, and TBA were reported below laboratory detection limits for all of the <br /> samples, consistent with the previous sampling event <br /> The groundwater gradient was calculated to be towards the east-northeast at an average gradient of <br /> 0 001 ft/ft Groundwater elevations in the monitoring wells increased 1 35 to 1 45 feet since the previous <br /> sampling event (December 2001) <br /> ATTACHMENTS <br /> • Table 1 Groundwater Monitoring Data <br /> • Table 2 Groundwater Analytical Results for Oxygenates and Additional Compounds <br /> • Figure 1 Site Location Map <br /> • Figure 2 Groundwater Elevation Contour Map (First Quarter 2002) <br /> • Figure 3 Groundwater Analytical Summary(First Quarter 2002) <br /> • Appendix A Field Data Sheets <br /> • Appendix B Sampling and Analysis Procedures <br /> • Appendix C Certified Analytical Reports and Chain-of-Custody Records <br /> P\ARCO\60801Quarterly120021Arco_6080_1 Q02 doc Delta <br />
