1 <br /> 4-1 <br /> 4. SUMMARY OF RESULTS <br /> A summary of the analytical results from current and past well samplings is presented in Table 1 Based on <br /> the water-level data for June 9, 1997 (Table 1), Smith Technology has interpreted the groundwater <br /> gradient and flow directions for the upper aquifer, as shown on Figure 3 In the local upper aquifer <br /> (Monitoring Wells MW-5, MW-6 and MW-7), the groundwater level dropped an average of 0 88 feet, <br /> ranging from 0 86 feet in Monitoring Well MW-6 to 0 91 feet in Monitoring Well MW-5 The apparent <br /> groundwater flow direction in the local upper aquifer is southeasterly at a gradient of approximately 0 005 <br /> (Figure 3) <br /> Laboratoryanalysis of the water sample collected on June 9, 1997 from Monitoring Well MW-5 indicates <br /> Y P g <br /> that TPH-G and BTEX were not detected in this sample MTBE was detected in the sample collected <br /> from Monitoring Well MW-5 at a concentration of 220 parts per billion (ppb) The next quarterly <br /> groundwater sampling is scheduled for the third quarter of 1997 <br /> 1997 2nd Quarter Groundwater Monitoring Report <br /> PL1w 194.273\REP0RM2N❑QTR597 RPT SPC[June 24 1997] <br /> • <br /> S <br />
