I <br /> observation points Three sets of readings were collected at 30 minute intervals from all <br /> of the observation wells During the operation of the blower, a PID was used to screen <br /> emissions from MW-1 The data that was collected is presented in Table 1 below <br /> TABLE 1 <br /> 1 VES Performance Test Data <br /> ' Well Distance Time Vacuum Flow rate PTD reading Ambient air <br /> Number from (inches water) (CFM) (ppm) bleed valve <br /> MW-1 at MW-1 <br /> ' 1540 Offscale 103 40 100%open <br /> MW-1 0' 1546 Offscale 108 10 50%closed <br /> 1548 Offscale 53 41 100% closed <br /> 1558 00 <br /> MW-6 100, 1625 00 <br /> ' 1658 00 <br /> 1554 00 <br /> MW-7 53' 1623 00 <br /> ' 1653 0 0 <br /> 1556 0 0 <br /> MW-8 49' 1624 00 <br /> 1654 00 <br /> Variations in the initial flow rates observed at MW-1 may be <br /> y attributable to several <br /> factors Clearing of pore space within the formation or well screen, errors in data <br /> collection and changes in blower performance may have all contributed to these <br /> fluctuations The variations are not deemed significant as observation well readings were <br /> ' collected after the flow rate had stabilized once the bleed valve had been completely <br /> closed <br /> 6.0 FINDINGS <br /> 6.1 Soil Sampling Results <br /> One soil sample was collected and analyzed from each of the three newly installed <br /> ground water monitoring wells All three of the samples selected for analysis were <br /> collected from a depth of ten feet below the ground surface This depth is believed to lie <br /> within the smear zone produced from the rising and falling of the water table seasonally <br /> American Geological Services,Inc <br /> CA95DE-029 <br /> 10 <br />
