DISCUSSION <br /> TPHG and BTEX compounds were detected in the samples collected from MW-1 through MW-7 and 1n <br /> the newly installed wells (MW-1B, MW-1C, MW-8, MW-813 and MW-8C) MTBE was detected in the <br /> samples collected from MW-1, MW-3 and MW-4 MTBE was not detected in the newly installed <br /> monitoring wells The analytical results of groundwater samples are generally consistent with previous <br /> sampling events <br /> The groundwater flow direction is towards the east-northeast with an average groundwater gradient of <br /> 0 011 ft/ft The groundwater flow direction and gradient are consistent with previous quarters The <br /> groundwater elevations decreased by approximately one foot across the site <br /> ATTACHMENTS <br /> • Table 1 Groundwater Monitoring Data <br /> • Table 2 Groundwater Analytical Results for Oxygenates <br /> • Table 3 Groundwater Flow Direction and Gradient <br /> • Figure 1 Site Location Map <br /> • Figure 2 Groundwater Elevation Contours (Third Quarter 2000) <br /> • Figure 3 Groundwater Analytical Summary(Third Quarter 2000) <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 /> PAVILION1MyDocuments\ARC0121681QTRLY1200012168Q300 Delta <br /> 11/30/00 <br />
