l <br /> DISCUSSION <br /> At the time of the second quarter 2004 monitoring event, groundwater was encountered in the monitoring <br /> wells at depths ranging from 5140 to 51 54 feet below ground surface (bgs) Groundwater elevations <br /> decreased between 0 45 and 1 51 feet in wells MW-13, MW-14, and AS-1 since the previous monitoring <br /> event (March 16, 2004) Groundwater in wells MW-13, MW-14, and AS-1 are fluctuating within historical <br /> ranges Wells MW-1 and VW were dry, consistent with historical data <br /> TPHG (6,000 µg/L), benzene (32 gg/L), MTBE (4 6 µg/L), and TBA (43 µg/L) were reported in well <br /> MW-13 TPHG was also reported in wells MW-14 (370 µg/L) and AS-1 (170 µg/L) 1,2-DCA was reported <br /> in wells MW-14 (22 Ag/L) and AS-1 (11 pg/L) DIPE, ETBE, TAME, or EDB were not reported in any of <br /> the wells 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 /> P1TeicherMtockton-I031Quarterly120041Teichert 2Q04 DOC STRATUS <br />
