The remainiig physicochemistry parameters remained relatively the same, less then 10% change over the period of the study (see Exhibit 1), as would be expected since the uptake of nitrate is the easiest process for the microbes which will later utilize the other parameters when nitrate levels become limiting Over the course of the study nitrate levels dropped 29% from baseline, while the general population increased 20% at T=14 and the selective counts increased 76 fold, resulting in an increase of 76 fold in overall degrader kinetics for the study Conclusions and Recommendations Based on the correlation and evaluation of all of the bench scale laboratory results collected, the data certainly indicates that a stimulatory bioremedial approach would be a viable option for site mitigation based on the parameters evaluated in this investigation Both the nutrient and oxygen augmentation provided similar results, however the nutrient augmentation study provided a larger increase in selective microbial counts Should a bioremedial approach be desired for this site, it would be BioJet's opinion to initially implement nutrient augmentation field treatability in a designated area(s) to establish injection and monitoring parameters to ensure otological and regulatory site specific objectives are achieved and mamtained prior to full scale implementation Physical site conditions should also be evaluated and taken into consideration Upon AES's review of this report BioJet personnel would be happy to discuss in detail a design and implementation for field activities Biologic would like to thank AES for the opportunity to perforin this investigation, and look forward to discussing this report and providing any assistance necessary in facilitating your remediation needs Should you have any questions, please feel free to call anytime at (209) 245-6044 Respectfully Ken Farrar BioJet, Inc
