Page 5 <br /> Mr Michael Infuma Jr, Senior REHS <br /> October 1 l, 2002 <br /> Groundwater Level Measurements <br /> As shown in Table 1, groundwater within the monitoring wells were measured at <br /> depths approximately 1 5 feet lower than the previous round of monitoring <br /> performed in June 2002 Groundwater depths ranged from 26 60 feet (below the <br /> top of the well casing) to 27 60 feet The corresponding groundwater elevations, <br /> evaluated during this monitoring period, ranged from minus (-)17 05 feet to <br /> —17 84 feet relative to mean sea level As shown in Figure 3, groundwater flows <br /> easterly at an approximate gradient of 5 17 x 10-3 feet per linear foot, which is <br /> generally consistent with historic trends <br /> Groundwater Sample Analytical Results <br /> Petroleum hydrocarbon concentrations were non detected in the sample from <br /> monitoring wells MW-1, MW-3 and MW-4 Higher petroleum hydrocarbon <br /> concentrations were measured in the groundwater sample collected from <br /> monitoring well MW-2 (see Table 2) Benzene and TPHg concentrations in the <br /> current MW-2 sample were measured at 12 000 micrograms per liter (ug/1) and <br /> 120,000 ug/l, respectively (see Figure 4) <br /> Oxygenate compounds were not detected in the samples collected from wells <br /> MW-1 and MW-3 The groundwater sample collected from well MW-4 contained <br /> an MTBE concentration of 1 ugll Oxygenates were not detected in the MW-2 <br /> groundwater sample, however, laboratory detection limits for these various <br /> compounds were relatively high due to equipment interference from the higher <br /> petroleum hydrocarbon concentrations in that sample <br /> Conclusions <br /> 1 Based on current monitoring data, groundwater was measured in the monitoring <br /> wells at a depth of about 26 to 28 feet below the ground surface Groundwater <br /> was evaluated to flow easterly at an approximate gradient of 5 17 x 10-3 feet per <br /> linear foot <br /> Current groundwater monitoring results indicate that relatively high <br /> concentrations of TPHg and BTEX compounds were detected in the MW-2 <br /> groundwater sample TPHg and BTEX compounds were not detected in the <br /> samples from monitoring wells MW-1, MW-3) and MW-4 <br /> i <br />
