DISCUSSION <br /> At the time of the third quarter 2004 monitoring event, groundwater elevations had decreased between <br /> 2 85 and 2 88 feet in wells MW-13, MW-14, and AS-1 since the previous monitoring event (June 22, <br /> 2004) Groundwater in wells MW-13, MW-14, and AS-1 are fluctuating within historical ranges Wells <br /> MW-1 and VW were dry, consistent with historical data <br /> TPHG (6,000 gg/L), benzene (20 µg/L), MTBE (1 1 µg/L), and TBA (35 gg/L) were reported in well <br /> MW-13 TPHG (410 µg/L) was also reported in well MW-14 1,2-DCA was reported in wells MW-14 (16 <br /> µg/L) and AS-1 (10 µg/L) DIPE, ETBE, TAME, or EDB were not reported in any of the wells <br /> Concentrations of hydrocarbons reported in wells are generally consistent with historical data The <br /> laboratory report indicated that the pH of the sample for well MW-13 was above the method detection limit <br /> of 2 As the results reported for this well are consistent with historical data, it appears the increase in pH <br /> has not affected data quality <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 /> i <br /> P 1Teichert\Stockton-1031Quarterly120041Teichert_3Q04 DOC STRATUS <br />
