DISCUSSION <br /> At the time of the third quarter 2003 monitoring event, groundwater was encountered in the monitoring <br /> wells at depths ranging from 52 55 to 52 75 feet below ground surface (bgs) Groundwater elevations <br /> decreased between 2 20 and 2 66 feet in wells MW-13, MW-14, and AS-1 since the June 17, 2003 <br /> monitoring event Wells MW-1 and VW were dry Groundwater elevations measured in the wells this <br /> quarter are the lowest since the fourth quarter 2001, when monitoring and sampling was re-instituted <br /> TPHG was reported in wells MW-13, MW-14, and AS-1 The highest concentration of TPHG (4,200 µg/L) <br /> was reported in well MW-13 Benzene (25 µg/L) was reported in well MW-13 MTBE was not reported in <br /> any wells during this sampling event 1,2-DCA was reported in wells MW-14 (31 µg/L) and AS-1 <br /> (8 1 µg/L) Concentrations of hydrocarbons reported in wells are generally consistent with historical data <br /> ATTACHMENTS <br /> • Table 1 Groundwater Elevation and Analytical Summary <br /> • Figure 1 Site Location Map <br /> • Figure 2 Site Map <br /> • Appendix A Field Data Sheets <br /> • Appendix B Sampling and Analysis Procedures <br /> • Appendix C Certified Analytical Reports and Chain-of-Custody Documentation <br /> • <br /> P 1Teichertl.Stockton-1031Quarterly120031Teichert_3Q03 DOC STRATUS <br />
