Geweke Pilot Study <br /> 3 1 March 1994 <br /> Program B <br /> Monitoring under Program A has detected impacts to ground water by inoculated bacteria in <br /> MW4 and/or MW14. Using the data collected in Program A, a correlation has been established <br /> between increasing CO2 and decreasing 02 levels and the presence of bacteria. Because of the <br /> necessary to analyze for bacterial count and composition. <br /> correlation, CO2 and 02 levels indicate the presence of introduced bacteria, it is no longer, it is necessary to expand the <br /> However <br /> ground water monitoring to include additional wells farther from the inoculation sites. EWl and <br /> MW5 are the ground water monitoring wells which are the next closest to <br /> Additional monitoring wells will be monitoredthe area of inoculation. <br /> , if necessary, to detect the edge of bacterial <br /> movement. <br /> Monitoring Points: MW4, MW14, EWI, and MW5 <br /> Constituents: DO and CO2 <br /> Sample Frequency: Mondays and Thursdays <br /> Program C <br /> Monitoring under Program A has detected impacts to ground water by inoculated bacteria in <br /> MW4 and/or MW14. However, using the data collected in Program A, no correlation may be <br /> made between increases in CO2 and decreases in 02 levels and the presence of bacteria. <br /> Therefore, we need to monitor both CO2 and 02 levels and bacterial numbers and composition. <br /> In addition, hydrocarbons will be monitored because bacteria may have been operating long <br /> enough to be able to detect a difference in hydrocarbon concentrations. <br /> M�uifadnfl Points Cmtituents <br /> Sample FreWiency <br /> MW4 and MW14 <br /> DO, CO2, bacterial Mondays and Thursdays <br /> counts and composition <br /> BTEX, TPHg, EPA601 Twice Monthly <br /> EWl and MW5 DO, CO2, bacterial Mondays and Thursdays <br /> counts and composition <br /> SOIL GAS/VAPOR MONITORING FOR THE PILOT STUDY <br /> In order to monitor a variety of airlbacteria permutations, we decided to turn off the air blower <br /> line to some of the wells. The air blower system is set up so that there are two main supply <br /> lines. One line supplies VW4, VWS, VW6, MW4, MW5, and MW14. The other line supplies <br /> VWI, VW2, VW3. VW7, and MW3, the air supply to this line was turned off. Bacteria were <br /> inoculated into VW 1, VW4, VWS, VW6, and MW4. MW is not connected to the blower but it <br /> is close to the inoculation/blower system. <br />
