Mr.,Bob. Marty (AGE) <br /> GLDM/Geweke <br /> August 3,. 2000 <br />�. -Page 2 <br /> COMMENT <br /> There appears;to be little substantive change with regard to physicochemical values associated,. <br /> with the samples tested since the previous sampling event. In.general,:physicochernical values <br /> remain lower than optimal for microbial growth and biodegradative activity, however; both. <br /> general and selective microbial subpopulations were .recovered, suggesting at least a modest ' <br /> Level of ongoing biodegradative activity. In fact, both.samples ,yielded -relatively. high <br /> proportion of selective„ biodegraders for ..this sampling. event, suggesting improved <br /> bioavailability of contaminant (possibly via recharge and/or leaching activity).. This finding may <br /> also indicate .tlie lowering of competing carbon substrates, facilitating the development-of a , <br /> higher proportion of target contaminant biodegraders. As suggested in -previous reports, <br /> supplementation. of the water with appropriate bionutrients .will likely improve microbial <br /> populationdynamics and enhance biodegradative activity: <br /> Should you h.ave•any questions concerning these results, please do.not hesitate to contact me. <br /> AKK;em <br />
