. Approximate Depth to Groundwater 28 83 to 3117 <br /> Direction of Groundwater Flow Southeast <br /> Groundwater Gradient o 002 to 0 007 <br /> DISCUSSION <br /> Results of this monitoring event indicate that the levels of dissolved hydrocarbons in wells MWA through <br /> MW-6 are generally consistent with levels detected in previous sampling events The groundwater flow <br /> direction (southeast) and gradient were generally consistent with previous sampling events Groundwater <br /> elevation increased 3 42 feet in the wells from the previous sampling event (November 1997) <br /> ATTACHMENTS <br /> • Table 1 Groundwater Monitoring Data <br /> • Table 2 Groundwater Analytical Results for Oxygenates (USEPA Method 8260) <br /> • Table 3 Historical Groundwater Flow Direction <br /> • Figure 1 Site Vicinity Map <br /> • Figure 2 Generalized Site Plan <br /> • Figure 3 Groundwater Contour Map (February 16, 1998) <br /> • Appendix A Sampling and Analysis Procedures <br /> • Appendix B Laboratory Analysis Reports and Chain-of-Custody Records <br /> • Appendix C Field Data Sheets <br /> . cc Elizabeth Thayer, California Regional Water Quality Control Board <br /> Will Smdh, Lincoln Properties <br /> SAC1N 1PJ010805108051400 8AS-98\7?? 1 <br />
