Using a medium for <br /> f <br /> hydrocarbonoclastic bacteria NO ,( ) , the range was 1.4 % 102 - 2..i x <br /> X 106 CFU/gm dry weight of soil . In June, 1487 all wells <br /> i <br /> containing water were analyzed microbiologically. <br /> - The microbial <br /> populations in the wells ranged'•on NA from 6.5 X <br /> 105 - 1.4 X 107 CFU/mL, and for the HC medium the range was 1.9 X <br /> IO 1.0 X 106 CFU/mL, It should be. noted that:' at MW-13, where <br /> free <br /> product wasvisible, the CFU were .2.:+1 X 106 CFU/mL and 6,' X <br /> 106 <br /> CFU/mL for Wand HC, respectively. '.This shows that the <br /> Presence of free proiuct, is.

The amounts and rate are determined from s <br /> the 0ptimiiation Study and will _ be-adjus <br /> ted.:as neededat the <br /> There are two sets of monitoring wells: interior wells <br /> within the area of. contamination, and . exter.ior wells which. are <br /> Outside the contamination zone and used to..demon <br /> strete .that <br /> , <br /> nutrient flow is under_:_control.--These--two--sets wells will be <br /> € Ti sampled under different regimes. <br /> -36- <br /> 1 <br /> 3 <br /> '• Vii.
